Automated pen tests have strengthened our security posture and reduced assessment effort

  • April 23, 2026
  • Review provided by PeerSpot

What is our primary use case?

My main use case for The NodeZero Platform by Horizon3.ai is performing quarterly pen tests on our enterprise and OT networks.

For those quarterly pen tests, we usually run them in the actual web UI interface, selecting what subnets we want to hit for pen tests, what vulnerabilities we want to use, and the whitelists that we have in place. We don't step on any sensitive devices, and then afterwards, we review the findings and remedy the problems.

What is most valuable?

The best features that The NodeZero Platform by Horizon3.ai offers include its set it and forget it type pen testing. You configure it once and then set it to automatically run during certain days, which is particularly useful, especially when you're a thin IT department.

That set-it-and-forget-it feature helps my team day-to-day by saving a lot of time, as we can set the pen test and then divert our attention to other things while the pen test is ongoing.

The NodeZero Platform by Horizon3.ai has positively impacted my organization by catching vulnerabilities and exploits that we wouldn't otherwise be able to find as easily or as quickly, so I'd say it helps better our cybersecurity posture.

What needs improvement?

The NodeZero Platform by Horizon3.ai can be improved in some ways, particularly regarding the test scan sometimes.

When the test scan doesn't work as expected, the runner sometimes acts up, and we usually have to run a command on it to fix it or sometimes reboot it. Other than that, the product works great.

For how long have I used the solution?

I have been using The NodeZero Platform by Horizon3.ai for about a year and a half.

What do I think about the stability of the solution?

The NodeZero Platform by Horizon3.ai is stable.

What do I think about the scalability of the solution?

The scalability of The NodeZero Platform by Horizon3.ai is pretty good, as you can throw in any number of subnets in the pen test, so I'd say it's very scalable.

How are customer service and support?

We have had no issues with their customer support; it seemed pretty solid.

I would rate the customer support of The NodeZero Platform by Horizon3.ai as an eight.

Which solution did I use previously and why did I switch?

We did not have a different solution before using The NodeZero Platform by Horizon3.ai.

How was the initial setup?

I wasn't involved in the pricing, setup cost, and licensing, but I've heard that it's pretty simple and easy.

Which other solutions did I evaluate?

We did not evaluate any other options before choosing The NodeZero Platform by Horizon3.ai.

What other advice do I have?

My impression of the solution's feature that allows security teams to fix and retest vulnerabilities instantly is that it's a very useful feature, and I highly appreciate that feature.

The platform's real attack capabilities have helped in identifying vulnerabilities in my on-prem systems by giving us a real-world example of what we should be prioritizing, which helps during the vulnerability management process, so it's helped us significantly.

We don't necessarily use the endpoint security effectiveness feature; we don't really pay attention to it.

The NodeZero Platform by Horizon3.ai has reduced our pen testing costs, but I don't have a specific number.

My advice to others looking into using The NodeZero Platform by Horizon3.ai is to utilize the one-click vulnerability or rescan feature for NodeZero.

I think they're also the reseller for the product.

I would rate this solution an eight overall.

Automated pen tests have strengthened security and provide detailed monthly remediation insights

  • April 20, 2026
  • Review provided by PeerSpot

What is our primary use case?

I have been using The NodeZero Platform by Horizon3.ai for about three years now.

I use The NodeZero Platform by Horizon3.ai to run scheduled penetration tests against my internal and external network resources.

I recently changed my hosting service and web hosting service, and along with that change, I decided to run another penetration test against it to ensure everything was functioning properly. I did find a vulnerability which I was able to quickly address and resolve.

I run this once a month in general, although I will run it whenever something new is introduced into my infrastructure. My monthly run reports provide me with data that I can review, and if I find anything in there that I did not see before, I can address it.

What is most valuable?

One of my favorite features of The NodeZero Platform by Horizon3.ai is the scheduling feature, which means I do not have to remember to run the penetration tests. Another feature I really appreciate is the remediation tasks that it provides. When it offers remediation guidance, it gives me steps to resolve the issue, which saves me time in determining what I need to do to remediate a certain vulnerability.

The remediation steps provided by The NodeZero Platform by Horizon3.ai are usually quite detailed and helpful. Occasionally, I will get one that does not offer a lot in the way of specific steps because the device on which it found the vulnerability is not a standard device that it recognizes. However, if it is a Windows box or Linux box, it is very good about giving me accurate information.

I believe that The NodeZero Platform by Horizon3.ai has kept me safer in a cybersecurity sense. It is one of a couple of different products I use for that purpose, but because I have cybersecurity insurance, I am required to run pen tests at least once a year. This product allows me the opportunity to run it as many times as I want, which is very beneficial because when new things are introduced into my network, I may not be able to identify these vulnerabilities until I run my next penetration test, which could be up to eleven months later.

Because I stay on top of these things, I am not usually caught off guard with a security issue that suddenly appears. I see them monthly and I do not have to generally perform any sort of emergency response that I would have had to do in the past when I had nothing in place.

What needs improvement?

I would love it if I could whitelist certain vulnerabilities that I consider not especially significant with The NodeZero Platform by Horizon3.ai. The NodeZero Platform by Horizon3.ai classifies them based on severity, and the severity for a lot of these things, such as threes, ones, and 0.01s, are generally things that I do not care too much about. I want to see them in a report when they appear the first time, but I would love it if I could simply check that one and indicate that I do not want to see a report about this one again because I am not going to take action on it.

For how long have I used the solution?

I have been working in this field for around thirty years.

What do I think about the stability of the solution?

The NodeZero Platform by Horizon3.ai is quite stable.

What do I think about the scalability of the solution?

It is kind of difficult for me to comment on The NodeZero Platform by Horizon3.ai's scalability because I have not had to change the scale. It certainly works fine in my rather small environment, but since I have not run it in a very large network environment, I cannot really say much more than that.

How are customer service and support?

Customer support for The NodeZero Platform by Horizon3.ai is awesome. I love the chat person I work with on chat. She is always super responsive and very patient and is able to get to the bottom of my problems, which are fairly infrequent. At the beginning, there were a few little hiccups that I was causing through some misunderstanding on my part, but she was very good.

Which solution did I use previously and why did I switch?

I previously used Fortelist, an annual service that they provided to run penetration tests on my network. The reason I switched is because I wanted to be able to run penetration tests more frequently, and it simply would not have been cost-effective to do it more often than one time a year. That is the main reason for the change.

How was the initial setup?

Interestingly enough, I have used that quite a bit in the past. The last time I ran my pen test, I for whatever reason was not able to quickly retest as conveniently as before. I am not really sure why that is, and I probably should just talk with Horizon3.ai about that.

Certainly, time has been saved with The NodeZero Platform by Horizon3.ai, and I would imagine money has been saved from the previous way of doing my pen tests, which were a yearly pen test that were quite expensive to do. There has been no change in employment or employees, but as far as the licensing costs, I think that was a big win for me.

What about the implementation team?

I did not have involvement in the evaluation process. I was not the one who evaluated it; I was the one who implemented it.

What was our ROI?

I believe The NodeZero Platform by Horizon3.ai has helped reduce my pen testing costs, but I cannot tell you exactly how much as I am not the person who paid for those services. However, I believe it was a significant reduction.

What's my experience with pricing, setup cost, and licensing?

I cannot really speak to the pricing as I was not involved in the purchase of it or any of the costs. I was the one that implemented it, and for that, I give it a thumbs up—it was awesome.

Which other solutions did I evaluate?

I think everything else is fine.

What other advice do I have?

The first time you run a test with The NodeZero Platform by Horizon3.ai, be prepared to triage because you are going to find things you had no idea you had.

It is because I have not had any serious problems for a long time. I would say that the very first time I ran The NodeZero Platform by Horizon3.ai, I did find many things such as open SFTP ports, open FTP ports, and open database ports that I was able to quickly address. I would say quickly, but it took a while because the platform found so many. However, it was super helpful because I did not have a single way to find those things before.

I give this review a rating of nine.
