Zscaler in focus: Security at scale or complexity at cost
What do you like best about the product?
Best thing about zcaler which i like is the ease of use and no specific need of deploying or managing appliances which makes it suitable for an organization with any type of workforce, it being remote, offsite or in office. It is also a full stack of internet security offering an ecosystem advantage
What do you dislike about the product?
Worst thing about zcaler as a user is that whenever we switch from work from home to in office or change networks anytime, it takes a long time to reconnect or it simply does'nt connect to network, because of which multiple diagnostic steps has to be taken.
What problems is the product solving and how is that benefiting you?
1. Secure internet access which keeps our data safe and prevent from connecting to unsafe networks
2. Different layer of security at different work environments. ex work from home, in office, off site etc
3. Ease of use as a user not in cybersecurity, the diagnostic steps although lenghty are easy to fix ourselves with some minor fixes rather than dependening on the it team

Securing the Modern Enterprise: A Deep Dive into Zscaler Internet Access
What do you like best about the product?
What I like best about Zscaler Internet Access is how streamlined and scalable the implementation process is, especially in distributed or hybrid environments. As an implementation engineer, I appreciate how ZIA eliminates the complexity of deploying and managing traditional security appliances by shifting to a cloud-native, proxy-based model.
What do you dislike about the product?
Policy evaluation order (URL & Cloud App Control vs. Firewall vs. DLP) can be non-intuitive for new admins; mis-sequenced rules sometimes produce “shadowed” policies that look correct in the portal but never hit in practice.Log retention in the portal tops out at 30 days unless you stream to external SIEM/Splunk, which adds extra lift and cost.
What problems is the product solving and how is that benefiting you?
Zscaler Internet Access (ZIA) solves the challenge of securing user internet traffic without relying on traditional perimeter-based security.
It provides cloud-delivered protection against web threats, data loss, and unauthorized access—regardless of user location—by enforcing consistent security policies across remote and on-site users.
As an implementation engineer, this benefits me by simplifying deployments, reducing the need for complex hardware setups, and enabling faster rollouts with centralized policy management. It also enhances visibility and control while supporting Zero Trust architecture, which aligns with modern security needs.
