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.
