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 problems is the product solving and how is that benefiting you?
Zscaler Internet Access (ZIA) primarily solves the limitations of traditional firewall-based security, which struggle to protect modern, cloud-driven environments. Legacy setups often fail to detect advanced threats, lack visibility into encrypted traffic, and create performance bottlenecks due to backhauling traffic through data centers.
One major problem it addresses is cybersecurity threats like malware, ransomware, and phishing. ZIA inspects all internet traffic (including SSL/TLS encrypted traffic) in real time.
Benefit: Users get secure and seamless connectivity without performance degradation from VPN backhauling.
ZIA also solves the problem of poor visibility and control over user activity and cloud applications. It provides centralized policy enforcement and granular controls over web traffic and SaaS usage.

What do you dislike about the product?
One area for improvement would be the initial setup and policy configuration, which can be complex for new administrators. The interface is powerful but may require some learning time to fully utilize all features.
In certain scenarios, there can be minor latency depending on user location and traffic routing. However, these are manageable and do not significantly impact overall security and performance

The "Backhauling" Problem
The Problem: In traditional networks, traffic from remote users or branch offices is routed back to the corporate headquarters (via MPLS or VPN) to be scanned by a central firewall before going out to the internet. This is called "hair-pinning" or "backhauling." It causes high latency (slowness) and requires expensive bandwidth at the HQ.
