Automated file scanning has reduced malware risk and protects our cloud document workflows
What is our primary use case?
My main use case for Antivirus for Amazon S3 is to protect the S3 storage buckets used for file uploads, document exchange, and backups, as well as web application content. I mainly use it for scanning user-uploaded files to S3, detecting malware in stored objects, protecting web application uploads, preventing infected files from reaching users, alerting SOC teams to suspicious uploads, and supporting cloud security compliance controls.
A quick specific example of how I use Antivirus for Amazon S3 day-to-day involves a customer portal where end users can upload documents for verification. Files are stored in Amazon S3, and there was concern that someone could upload a malicious document disguised as a normal file. After enabling Antivirus for Amazon S3 scanning, suspicious uploads are automatically flagged before being consumed by downstream systems. In one case, a file exhibiting malicious macro behavior indicators was quarantined for review, which significantly reduces the risk for internal users and the application's workflow.
For monitoring, I use Antivirus for Amazon S3 to review malware detections, manage the quarantine workflow, validate bucket coverages, integrate alerts with SOC tools, and support a secure file upload process. I utilize all of these features on a day-to-day basis.
What is most valuable?
The best features Antivirus for Amazon S3 offers include quarantining, which is very useful for a SOC team, alerting features, and a user-friendly AWS workflow. It even integrates with S3 events and automation flows to allow for automated scanning, eliminating the need for manual checks. It is crucial for checking the automated processes and protecting cloud storage uploads, especially when users upload files, thereby enhancing compliance posture.
Automation and integration with S3 events make my workflow easier and more efficient because it stops suspicious files immediately and notifies the security team. In one case, when a malicious or suspicious file was uploaded to an S3 bucket, instead of allowing the file to stay in a production bucket or letting a user download it, it automatically moved to the quarantine bucket and notified the security team. It blocks public access, tags infected files accordingly, and prevents downstream systems from using flagged files. For example, one of the end-users uploaded an Excel file to the portal that contained malicious macro code. Without quarantine, a finance or admin user could have downloaded and opened the file, infecting their endpoint. However, with quarantine enabled, the file is scanned post-upload, and if it is malicious, it is detected and moved to the quarantine bucket, preventing any dangerous files from reaching users. This process stops threats at an earlier stage.
Automatically malware scanning for uploaded files is the best feature given the nature of S3 storage. Even with such scanning, uploaded content can still become an infection path, making automatic file malware scanning the most valuable feature.
Antivirus for Amazon S3 has positively impacted my organization by reducing malware risk from uploads, decreasing manual review efforts, speeding up responses to suspicious files, enhancing trust in customer-facing portals, and improving our cloud storage security posture.
What needs improvement?
Improvements can be made to Antivirus for Amazon S3 since it sometimes generates false positives on rare file types, which requires tuning based on workloads. Additionally, reporting on executive dashboards should be enhanced, and there may be a need for cost adjustments. Multi-cloud support would strengthen the offering, and these aspects, along with user interface enhancements, should be considered.
For how long have I used the solution?
I have been using Antivirus for Amazon S3 for more than 1.6 years, mainly in the AWS environment where files uploaded to S3 buckets require malware scanning before customer access.
What do I think about the stability of the solution?
Antivirus for Amazon S3 is stable with no major issues, and the integration overall works well.
What do I think about the scalability of the solution?
Scalability is good with AWS native architectures in place.
How are customer service and support?
The quality of customer support is dependent on the vendor, but in my opinion, it is all good.
Which solution did I use previously and why did I switch?
I previously used Trend Micro Cloud file scanning solutions, but I switched to Antivirus for Amazon S3 because it is very easy to use and is trusted by many by default.
What was our ROI?
I have indeed seen a return on investment since Antivirus for Amazon S3 prevents malware incidents, reduces the need for manual file checking, improves consumer trust, and strengthens compliance controls. These metrics represent significant returns on investment.
What's my experience with pricing, setup cost, and licensing?
I was not part of the pricing, setup cost, or licensing discussions, but based on my knowledge, it generally depends on business criticality and external exposure, which justifies the expenses when files are uploaded.
Which other solutions did I evaluate?
Before choosing Antivirus for Amazon S3, I evaluated custom antivirus pipelines, native AWS security workflows plus Lambda, and Trend Micro Cloud file scanning solutions, and I switched to Antivirus for Amazon S3 due to its trusted reputation.
What other advice do I have?
My advice for others looking into using Antivirus for Amazon S3 is that if any organization or application deals with file uploads to S3, they should not assume the storage is secure on its own. Scanning content before internal use or download access is vital, and organizations need to consider all these aspects before making a choice.
Antivirus for Amazon S3 is a very practical security control for an AWS environment that handles uploads or shared files, effectively closing a common blind spot in cloud storage security. I would rate this product an 8 out of 10.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)
Automated file scanning has strengthened compliance and streamlined secure document workflows
What is our primary use case?
Our primary use case for Antivirus for Amazon S3 is scanning files uploaded by external partners and end-users before those files flow into our downstream processing system. We have S3 buckets that act as our ingestion points, documents, Lambda deployment packages, and third-party data files, all of which need to be validated for malware before they touch any internal system. Antivirus for Amazon S3 sits right at the entry point, automatically scanning every object as it lands. It essentially acts as our first line of defense at the cloud storage layer.
One concrete example of how I am using Antivirus for Amazon S3 day-to-day is that we exposed an S3 endpoint to a network of around 40 external vendors who regularly uploaded compliance documents and reports. Before Antivirus for Amazon S3, we had a basic Lambda and ClamAV setup that constantly broke down with files over 400 MB and needed constant maintenance. After switching, we deployed the solution in under 15 minutes using the CloudFormation template, and within the first month, we caught three infected uploads from different vendors that could have otherwise made it into our document processing queue. That incident alone justified the switch for our security team.
What is most valuable?
The best features Antivirus for Amazon S3 offers are event-driven scanning and automated object tagging. Event-driven scanning means the moment a file hits S3, it is already being scanned. No polling, no delay, and no manual triggers are required. Object tagging is where the real downstream power comes in. Files get tagged as clean or infected, and our processing jobs only pick up objects tagged as safe. The decoupling means we do not have to tightly wire our application logic to the security layer. Multi-engine support from Sophos, CSS Premium, and ClamAV is also a significant benefit for detection coverage.
These features have genuinely reduced the operational burden on our security and DevOps teams. Before, someone had to manually investigate an alert, trace where a file came from, and then decide what to do. That easily took 45 minutes to an hour per incident. Now, the infected file is automatically quarantined or deleted, tagged with metadata, and the relevant team gets a Slack notification within seconds. We estimated it saved our team around 8 to 10 hours a month in manual work alone. The development team does not need any specialized security knowledge to work with it. It is just part of the S3 workflow.
The positive impact of Antivirus for Amazon S3 on my organization has been most visible in three areas: security posture, compliance confidence, and developer velocity. From a security standpoint, we have eliminated the risk of malicious files entering our core systems from external sources, which was a major audit finding we were trying to resolve. From a compliance angle, we can now demonstrate continuous, automated scanning of all ingested objects, which directly supports our SOC 2 or ISO 27001 obligations. From a developer standpoint, the team does not have to think about security at the application layer for every new upload workflow. It is already handled at the infrastructure level.
What needs improvement?
If I had to point to one main area where Antivirus for Amazon S3 can be improved, it would be the reporting and analytics side of things. The current dashboard gives you what you need for operations, but if you want rich, forensic-level reporting, such as tracking infection patterns over time, which upload sources are riskier, or trending data by bucket, you have to build that system yourself on top of the logs. I would love to see more out-of-the-box reporting capabilities without needing to pipe everything into a SIEM first. It is not a deal-breaker, but it would make the product much stronger from a security analytics perspective.
Regarding needed improvements, I think about documentation, debugging, and monitoring. Documentation is generally good, but there are some edge cases, particularly across cross-account deployment configuration, where the documentation feels thin. I had to piece together information from a Stack Overflow post and a support ticket to get it right. For debugging, clearer error messaging from the scanning engine when something fails silently would be helpful. Sometimes a scan just does not trigger, and there is no obvious signal in the logs as to why. Better diagnostic tooling there would save a lot of troubleshooting.
For how long have I used the solution?
I have been using Antivirus for Amazon S3 for about one and a half to two years now, primarily across our cloud-native ingestion pipelines.
What do I think about the stability of the solution?
Stability for Antivirus for Amazon S3 has been excellent in two years of use. We have had zero unplanned outages attributed to the solution. The Fargate-based architecture means there is no underlying compute to babysit, and we have never seen it fall under high load. We have had spikes where thousands of files were uploaded in a short window, such as during a large batch data transfer, and the scanning kept pace without any noticeable delay or backlog. That kind of reliability is what you need when it is sitting in a production security pipeline.
How are customer service and support?
My experience with customer support for Antivirus for Amazon S3 has been very positive. The one significant support request we raised around cross-account deployment configuration was resolved within two business days with clear, technically accurate guidance. The support team clearly knows the product deeply and does not escalate everything to a generic FAQ. I have also seen them release a bug fix within 48 hours after a community-reported issue, which shows that they are actively engaged. For a cloud marketplace product at this point, that level of responsiveness is genuinely impressive.
Which solution did I use previously and why did I switch?
Previously, we were running a homegrown solution built on ClamAV with an AWS Lambda function. It worked initially, but it had a hard file size cap around 400 MB, required constant maintenance whenever ClamAV definitions updated, and had no real management interface. Everything was manual. As our S3 footprint grew, the external upload volume increased. It just did not keep up. The tipping point was when we needed multi-region support, and the DIY solution could have required significant rework. That is when we started evaluating purpose-built solutions.
How was the initial setup?
The setup experience was genuinely impressive. We were up and scanning in under 15 minutes using the CloudFormation template. The 30-day free trial with up to 500 GB of scanning was also very generous and gave us enough time to validate it properly before committing.
What was our ROI?
I have seen a return on investment from Antivirus for Amazon S3, and it has been strongly felt and quick to materialize. We eliminated the maintenance overhead of our old Lambda-ClamAV setup, which was consuming roughly 5 to 6 engineering hours per month in patches, fixes, and size limitation workarounds. We have reduced our security incident response time related to S3 uploads by about 40%, and the automated quarantine workflow alone has prevented at least two incidents that would have caused downstream data corruption. When you factor in the cost of a potential breach versus the subscription cost, the math is very clearly in favor of this product.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, setup cost, and licensing for Antivirus for Amazon S3 started with pricing at $49 per month for the first 100 GB scanned on the pay-as-you-go model and then scales on a per-GB basis after that. For the volume we are operating at, it has been very predictable and reasonable. It is far cheaper than staffing someone to manage a homegrown solution.
Which other solutions did I evaluate?
Before choosing Antivirus for Amazon S3, we looked at a few options seriously, such as Amazon GuardDuty Malware Protection for S3, which was the obvious first choice given its native AWS integration, but it did not give us the level of control and configurability we needed, particularly around custom tagging and quarantine workflow. We also evaluated BucketAV and MetaDefender Cloud. BucketAV was appealing for its simplicity and open-source nature, but it lacked enterprise-grade multi-engine support. MetaDefender had great detection, but required data to leave our AWS environment, which was a non-starter. Antivirus for Amazon S3 hit the right balance of control, deployment simplicity, and detection quality.
What other advice do I have?
Something I do not think gets enough attention about the features is the Terraform support. We follow infrastructure-as-code practices, and being able to define and enforce antivirus policies on S3 buckets at creation time through Terraform templates has been transformative. Now, every new bucket across all our environments is automatically protected the moment it is provisioned. There is no room for human error or someone forgetting to enable scanning. The multi-region deployment support is also worth noting for teams that operate across multiple AWS regions, which we do.
If you are running any kind of external-facing upload workflow on S3, do not wait to put a proper scanning layer in place. The AWS shared responsibility model is clear. AWS does not scan your S3 data for threats. That is on you. Antivirus for Amazon S3 is one of the fastest ways to close that gap without building something yourself. Take the 30-day free trial seriously. Test it with your actual workloads and spend time understanding the tagging and quarantine configuration. That is where you will unlock the most value in your downstream automation. I would rate this product an 8 out of 10.

Automated tagging has transformed our cloud file protection and now improves security compliance
What is our primary use case?
I mainly use Antivirus for Amazon S3 for native AWS and Amazon GuardDuty Malware Protection on the S3. I also use it as a third-party marketplace app and as an open-source and DIY solution. These are the main ways I have been using it.
How has it helped my organization?
Antivirus for Amazon S3 has had a positive impact on my organization, and I notice improvements in security.
Since using Antivirus for Amazon S3, I have seen that it is a very key feature for me as it improves compliance and also reduces risk. When you have files with an automated object target on them, the solution will put them in quarantine or delete them immediately. This flags anomalies effectively.
I have noticed measurable outcomes since implementing Antivirus for Amazon S3, as it saves time. Since we are using automated tagging, we do not rely on detections, such as getting an alert and then having a human go and remediate the issue. We try to make these actions as simple as possible and have them performed automatically. The actions immediately put the anomaly in quarantine, and any engineers can check in later.
What is most valuable?
The best features Antivirus for Amazon S3 offers include event-driven execution, automated object targeting, immediate remediation, in-tenant processing, data sovereignty, and scale and archiving support.
Out of those features, automated object targeting stands out as the most valuable in my day-to-day work because it allows me to automatically apply a metadata tag to S3 objects as a post-scan, for instance, identifying them as infected or clean.
I would add that you rely on humans for protection in your operation, just as you do with the automated object target. An infected tag will instantly trigger an automated workflow and bridge on AWS Lambda to immediately delete the file or move it to a completely isolated area, such as quarantine. If the file is not being deleted immediately, it is put in quarantine.
What needs improvement?
I do not have suggestions on how Antivirus for Amazon S3 can be improved at this time. I am still exploring the app and trying to see what the product can do with the features more.

Automated file scanning has strengthened cloud security and improves threat response efficiency
What is our primary use case?
Antivirus for Amazon S3 ensures that all files uploaded to S3 buckets are scanned for malware before they are accessed by applications and end users. This is especially important for customer-facing applications where users upload files such as documents, images, or reports.
In day-to-day operations, whenever a file is uploaded to an S3 bucket, it triggers an automated scanning process. Antivirus for Amazon S3 scans the file in real-time and based on the result, we either allow the file, quarantine it, or block access if it is malicious.
For example, in one implementation, I integrated S3 antivirus scanning with our security monitoring system. When an infected file is detected, an alert is generated and the file is automatically isolated. My team then reviews the alert, validates the threat, and ensures that no downstream systems are impacted. This process has significantly reduced the risk of malware entering our environment and improved the overall data security, especially for cloud-hosted applications.
What is most valuable?
Integrating Amazon S3 antivirus scanning with our security monitoring systems has significantly streamlined my team's workflow and improved our response efficiency. Earlier, live file validation and threat checks involved more manual effort and detailed analysis. After integration, the entire process became automated.
Whenever a file is uploaded to S3, it is scanned in real-time and the results are directly sent to our SIM security monitoring tools. This has reduced our mean time to detect and mean time to respond by around 45% to 55%, as the results are generated instantly and my team can take actions without delay.
For example, if a malicious file is detected, it is automatically quarantined and a high-priority alert is triggered, allowing us to investigate immediately. Additionally, the automation has reduced manual workload by nearly 35%, as my team no longer needs to perform repetitive file checks or validation. The solution has also improved visibility across our environment, enabling us to detect threats more effectively and respond proactively. Overall, the integration has made our security operations more efficient, faster, and more reliable.
What needs improvement?
Overall, Antivirus for Amazon S3 works well, but there are a few areas where it could be improved. One challenge I have observed is around fine-tuning and visibility. While the scanning and alerting are effective, having more detailed insights into why a file was flagged or better categorization of threats would help in faster analysis and decision-making.
Another area for improvement is centralized reporting and dashboarding. While basic logs are available, more advanced user-friendly dashboards with deeper analytics would make it easier for teams to track trends and generate reports for management or compliance.
In terms of integration, although it integrates well with AWS services, simplifying the configuration and deployment for new environments would be beneficial, especially for teams that are not deeply experienced with AWS automation workflows. Additionally, improving false positive tuning capabilities would help reduce unnecessary alerts and further optimize operations.
These are more enhancements than major issues. Overall, Antivirus for Amazon S3 is reliable and effective for securing S3 environments.
For how long have I used the solution?
I have been using Antivirus for Amazon S3 for around two years as part of my cloud security implementation.
What other advice do I have?
Antivirus for Amazon S3 plays a critical role in our overall layered security strategy. It acts as a key control point at the storage layer, ensuring that any file entering our cloud environment is validated before it is used by applications or shared with users. I integrate it with other security solutions such as SIM, access control policies, and network security tools to create a defense-in-depth approach. This helps us to not only detect malware but also correlate threats across different layers of our infrastructure.
Additionally, it supports compliance requirements by ensuring that all stored data is scanned and secure, which is especially important for industries handling sensitive data. Overall, it fits seamlessly into our cloud security architecture by providing automated protection, improving visibility, and reducing the risk of malware propagation across systems.
Additionally, my advice is to focus on proper integration and automation from the beginning. The real value of Antivirus for Amazon S3 comes when it is fully integrated with services such as S3 event triggers, Lambda, and your security monitoring or SIM platform. I would also recommend defining clear workflows for how to handle infected files, whether to quarantine, delete, or alert, so your response process is consistent and efficient. Another important point is to monitor and tune the solution regularly, especially to reduce false positives and improve detection accuracy over time. Lastly, ensure it is aligned with your overall security strategy and compliance requirements rather than using it as a stand-alone solution. When implemented correctly, it becomes a very effective layer in a defense-in-depth approach. I would rate this solution an 8 out of 10 overall.

Amazon Web Services (AWS)
Automated file scanning has created a real‑time trust boundary for all external uploads
What is our primary use case?
My primary use case for Antivirus for Amazon S3 is to secure uploaded files before they are consumed by downstream systems. For example, one workflow involves users uploading documents such as PDFs or images to an S3 bucket via web applications. Since all these files come from external resources, we treat them as untrusted. When a file is uploaded to S3, it triggers an event notification that invokes an AWS Lambda function. The Lambda pulls the objects and scans them using an antivirus engine such as ClamAV. If the file is clean, the tag is set to safe, and it is moved to a processed bucket where downstream services can access it. If it is infected, we quarantine the file in a separate bucket and trigger alerts via SNS and Slack for visibility.
What is most valuable?
Antivirus for Amazon S3 offers several best features, including automatic malware scanning. The core feature automatically scans files when they are uploaded to S3, detecting viruses, ransomware, Trojans, and other threats. When working with trusted inputs, user uploads, third-party data, and event-driven and real-time processing, the service provides object tagging and metadata-based decisions, automated responses, multiple scanning engines, visibility logging and integration, fully managed and scalable infrastructure, flexible scanning modes, and compliance with security standards such as ISO 27001 and SOC 2 for secure data injected into pipelines.
The two features I find most valuable in Antivirus for Amazon S3 are event-driven scanning and object tagging. Event-driven scanning stands out because it makes the entire workflow real-time and automatic. As soon as a file is uploaded to S3, it gets scanned without any manual trigger. This is critical in production because it ensures no untrusted files sit around waiting to be processed; threats are handled immediately. Object tagging is equally important because it simplifies downstream decisions. Instead of tightly coupling services, we rely on tags such as 'clean' and 'infected'. For example, only files tagged as 'safe' are picked up by processing jobs. This approach keeps the jobs loosely coupled and easy to scale.
Antivirus scanning has a clear positive impact on security, automation, and developer velocity in my organization. From a security standpoint, it has eliminated the risk of malicious files entering downstream systems. Before this implementation, uploaded files were a blind spot. Now we ensure a restricted trust boundary where only scanned and verified files are allowed to move forward. We saw a reduction in security incidents related to file uploads because threats were stopped at injection. This helps us enforce a zero-trust approach for all external data. From a reliability perspective, failed scans default to untrusted, so nothing slips through.
What needs improvement?
One area for improvement in Antivirus for Amazon S3 is in handling large files efficiently. More seamless native support for large object scanning without needing custom ECS Fargate setups would simplify the architecture. Another improvement would be deeper policy control. The service also needs better visibility and reporting for logs and events. Cost optimization is frequently needed because scanning can become more expensive at scale, so smarter detection or scaling mechanisms would help reduce redundant scans. Additionally, better workflows for handling false positives, such as automating a rescan or approval pipelines, would reduce operational overhead.
Integration, support, and documentation are areas where Antivirus for Amazon S3 has room to improve. From an integration standpoint, setting up antivirus scanning often requires stitching together multiple services including S3, events, Lambda, IAM roles, and sometimes EC2 or EFS for large workloads. Having more native integration would be beneficial. On the support side, troubleshooting can be challenging, especially when a scan fails due to timeouts. The documentation is decent, but it is often fragmented. Having one or more end-to-end reference architectures, especially for real-world scenarios such as high-volume uploads or large file handling, would be helpful.
For how long have I used the solution?
I have been working with antivirus scanning for Antivirus for Amazon S3 for approximately three years.
What do I think about the scalability of the solution?
We have seen a measurable impact from using Antivirus for Amazon S3. There were several measurable improvements after we implemented antivirus scanning. From a security perspective, we reduced the risk of malicious file injection significantly. We ensured scans happened asynchronously so it did not impact user-facing latency. For scalability metrics, we have implemented security measures to handle spikes in uploads without additional operational overhead. For false positive handling, we tuned the system to minimize false positives, which reduced unnecessary alerts.
What other advice do I have?
One important point to add is that the workflow with Antivirus for Amazon S3 has significantly improved our security posture without slowing down development. Before implementing antivirus scanning, there was always a risk of malicious files being consumed by downstream services. By automatically scanning at the S3 level, we created a clear trust boundary where only verified files could move forward.
My advice to others looking into Antivirus for Amazon S3 is to design it as part of your pipeline from day one, not as an afterthought. First, treat all uploaded files as untrusted and enforce a clear flow. Scan immediately at upload and only allow clean files to move forward to avoid a security gap later. Second, keep the architecture simple and event-driven. Third, plan for scale early, especially for large files. Finally, invest in monitoring and failure handling. Ensure failed scans default to untrusted and set up alerts so nothing slips through silently. I would rate my overall experience with Antivirus for Amazon S3 as an eight out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Automated scanning has provided continuous data protection and supports audit readiness
What is our primary use case?
My main use case for Antivirus for Amazon S3 is to utilize an S3 bucket to put static content in, as part of a web app proof of concept that I have been running, and also user content generated from the website. Sometimes I back that up and store it in S3. Using Antivirus for Amazon S3 is really about performing those automated security scans to make sure that the data that is being stored is secure.
A quick specific example of how I use Antivirus for Amazon S3 in my workflow is for storing static content for a website I have been running, which is a proof of concept blogging website. For example, I am storing images for the blog in S3. Additionally, I carried out a survey on my blog and website that generated user responses, which then get stored in S3. When these objects get stored there, the automatic antivirus scanning, which is deployed on AWS Fargate, gets triggered to make sure that the data being uploaded is indeed secure.
What is most valuable?
In my experience, the best feature Antivirus for Amazon S3 offers is increased security. Because you set and forget it, once you are uploading data within your S3 bucket, it is continually getting scanned. The fact that the scanning occurs within the AWS account means data never leaves your AWS account, which is also a good security feature. It is real-time, and you can carry out retroactive scans as well. You can even have it API-driven, so before uploading the file to the S3 bucket, you can have it scanned first, before it is being written.
Antivirus for Amazon S3 has positively impacted my organization by increasing security. I have not actually had any files come back as being insecure, but that is because I have also manually checked the files to make sure that they are secure, and they are. If there was insecure data, I would think that this would pick it up. I have not seen the benefit yet, but that is purely because the data I have been using is already secure. I suppose other organizations which are maybe trying to meet audit requirements would benefit from having this tool because the data is continually being scanned, which would also help audits.
What needs improvement?
Antivirus for Amazon S3 could be improved by addressing that it is a little bit complicated to set up because you have to deploy it via CloudFormation or Terraform, and it can be a little bit difficult trying to troubleshoot the image or container issues. I have definitely found that. The error logs also are not always the clearest, so it does take a bit of a learning curve. The CloudWatch logs could also be better; I have noticed it streams them to different CloudWatch log streams, so it can be difficult to consolidate that data together. If you had a lot of data that generated many different logs, that could be quite difficult and time-consuming.
For how long have I used the solution?
I have been using Antivirus for Amazon S3 for about two years.
What do I think about the stability of the solution?
Antivirus for Amazon S3 is stable; I have never noticed an instability issue.
What do I think about the scalability of the solution?
Antivirus for Amazon S3 is highly scalable. I could use it for all my S3 buckets, so there are no issues from scalability perspectives.
How are customer service and support?
Customer support for Antivirus for Amazon S3 gets a ten out of ten. It is Amazon enterprise support if my organization has it, so it ties into that. There are no issues from a customer support perspective.
How would you rate customer service and support?
What was our ROI?
I have not seen a return on investment yet as I have not had any insecure data within my cloud account, and because of that, there has not been anything flagged as being insecure. The price of security is really significant, as if you do not have security, the cost of it is much greater than the cost of you actually doing it. You would always hope that you would never have a security issue, so peace of mind is really the main benefit here. Organizations could definitely be helped in their audit processes from using this tool, which alone would save a lot of time and thus money for organizations.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, setup cost, and licensing for Antivirus for Amazon S3 is good. I know in the AWS documentation, the pricing is always quite clear, and due to that, I have had no issues.
Which other solutions did I evaluate?
Before choosing Antivirus for Amazon S3, I did not evaluate other options, and that is just because I was using S3 buckets within AWS. I wanted to use their own integrated solution so that it would work with their shared security responsibility model. I could have potentially spun up a container and then deployed a custom solution, but I did not want to do that because it would have taken too much time. The benefit here was that because it is Amazon-managed, it is a lot quicker to get it going.
What other advice do I have?
I would recommend Antivirus for Amazon S3 to others looking into using it because it is very easy to set up from the perspective that it is already in AWS. You just have to have some initial development time to write the code to deploy it. After that, there is not too much management unless troubleshooting is needed. I would think most people would not be using a custom solution, so this is much better than not having something.
I rate Antivirus for Amazon S3 a nine out of ten. I give it a nine because it is a very good tool that leads to peace of mind, but it is a bit complicated to use, a bit difficult to troubleshoot, and also a bit difficult to consolidate the data in CloudWatch to see all the different log streams that are generated.

Automated cloud file scans have protected shared data and improve customer audit readiness
What is our primary use case?
My main use case for Antivirus for Amazon S3 is that S3 objects are generally uploaded to the cloud by different clients, and those S3 objects are being consumed by our ECM products.
We upload all the codes of our Lambda functions to S3 because they are large in volume. It may happen that our SCA tools and node modules that are getting uploaded may have vulnerable content or objectionable content, so we use Antivirus for Amazon S3 for scanning them.
What is most valuable?
Antivirus for Amazon S3 offers some of the best features including deployment using Terraform, the ability to scan new and existing objects, very quick setup time, multiple engine support such as Sophos, CIS Premium, and CIS Secure, and extensive vendor support through many marketplaces.
These features benefit my workflow because whenever a Lambda is being deployed, it can be triggered at any time. While GitHub and our SCM are building it, during the time when it is being posted to S3 or being downloaded into execution, it is scanned very quickly before Lambda pulls it up, unzips it, and executes it.
Antivirus for Amazon S3 has positively impacted my organization because it has improved our bank database customer experience for our bank customers.
