Powerful Cloud Security with Centralized Policy Management in Zscaler Internet Access
What do you like best about the product?
One of the best things about Zscaler Internet Access is its strong cloud-based security architecture. It provides real-time protection against web threats, malware, and unauthorized access, which significantly improves overall security posture without relying on traditional on-premise firewalls.Another key advantage is its centralized policy management. Administrators can control and enforce security policies across all users and locations from a single dashboard, making it highly effective for remote and hybrid work environments.I also appreciate the granular URL filtering and access control, which allows organizations to block or allow traffic based on domains, URLs, or IPs. This helps maintain compliance and prevents risky browsing behavior.Finally, features like SSL inspection, DLP (Data Loss Prevention), and bandwidth control provide deep visibility into traffic and help prevent data leaks, making it a complete secure web gateway solution.
What do you dislike about the product?
One of the main drawbacks of Zscaler Internet Access is performance and latency issues. Since all traffic is routed through Zscaler’s cloud, users sometimes experience slower internet speeds and delays, especially during peak hours or in certain regions.
I also find that troubleshooting can be difficult. Logs and visibility are sometimes limited, making it harder to quickly identify and resolve issues when something breaks.
Additionally, Zscaler can feel overly restrictive at times. Its aggressive security policies may block legitimate websites or applications, requiring frequent manual adjustments and exceptions.
concern is cost. Zscaler is considered a premium solution, and licensing—especially for advanced features—can be expensive compared to traditional firewalls or alternative solutions.

What do you dislike about the product?
It's easy for an admin to accidentally create overlapping roles and troubleshooting exactly why a specific site is blocked can sometimes feel like finding a needle in a haystack. Mainly, developer tools like Docker, Python, and Git use their own internal trust stores instead of the system's certificate store, leading to problems when Zscaler Internet Access tries to inspect this traffic. It frequently breaks the developer environment, requiring significant time to build workarounds. Additionally, when a user moves from a wired connection to Wi-Fi or a 5G hotspot, the Zscaler client connector can get stuck, leaving the user without internet access for up to sixty seconds. Finally, during network transitions, the client connector isn't always as seamless as hardware-based breakouts, especially on Mac OS or Linux.
What problems is the product solving and how is that benefiting you?
Zscaler Internet Access eliminates VPN lag with direct cloud access and enhances security with AI-powered SSL inspection, reducing latency by 4% and replacing expensive hardware. It inspects encrypted traffic and turns laptops into secure branches, addressing hybrid work challenges and legacy VPN limitations.
