Zscaler Internet Access Reviews & Product Details

Zscaler Internet Access provides a robust, cloud-native security approach that removes the need for traditional hardware such as firewalls and VPNs, helping reduce both costs and operational complexity. Built on a Zero Trust architecture, it follows a strict “never trust, always verify” model, ensuring every user and device is authenticated before access is granted, which in turn helps minimize the risk of unauthorized entry and broader cyber threats. A standout capability is its full SSL/TLS inspection, which enables analysis of 100% of encrypted traffic and helps uncover hidden malware that can otherwise remain buried in HTTPS communications.

When accessing Zscaler Inter Access, users occasionally experience slower internet and application performance, especially when traffic is routed through distant data centers. As a result, overall performance can be highly dependent on location, ISP quality, and configuration. Integration can also be complex, particularly with legacy systems or existing infrastructure, and it often requires additional troubleshooting and customization. In addition, the Zscaler client connector has been reported to have stability issues, such as tunnel drops and device compatibility limitations—especially in mobile or mixed network environments—which can negatively affect the user experience.

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.

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. Review collected by and hosted on G2.com.

Some users have noted that Zscaler Internet Access can feel complex during the initial setup, especially when it comes to policy configuration. There are also occasional false positives in threat detection, and the limited ability to customize reporting can be challenging. Pricing for advanced features may be another consideration, particularly for smaller organizations. Review collected by and hosted on G2.com.

I use Zscaler Internet Access primarily for its application control, which offers granular features for creating policies department-wise. I appreciate how it utilizes zero trust internet access, verifying every request based on identity, device posture, and policy, which significantly enhances security. Additionally, I find that the initial setup is very simple, particularly if you're migrating from another CASB solution to Zscaler Internet Access. Review collected by and hosted on G2.com.

There is all things up to the mark but while we found any issues related to the SSL blocked url or services we need dive into analytics and logs in more they can improve the Logs visibility which can help to create bypass or whitelist the same thing. Review collected by and hosted on G2.com.

What I like most about Zscaler Internet Access is its cloud-native zero-trust architecture, which allows secure internet access for users regardless of location. It provides strong threat protection by inspecting encrypted traffic and blocking malware, phishing, and other web-based attacks. I also appreciate the centralized policy management and visibility it gives administrators, making it easier to control user activity and enforce security policies. Additionally, since it is delivered from the cloud, it eliminates the need for traditional hardware firewalls and improves performance for remote and hybrid users Review collected by and hosted on G2.com.

One challenge with Zscaler Internet Access is that it can sometimes introduce latency because traffic is routed through cloud security inspection points before reaching the destination. In some cases, this may affect performance for bandwidth-intensive applications or users located far from Zscaler data centers. Additionally, the initial configuration and policy management can be complex, especially when integrating with existing infrastructure or legacy applications. The pricing model can also be relatively high for some organizations, particularly smaller companies that may not require the full feature set. Review collected by and hosted on G2.com.

I like Zscaler Internet Access for its direct to cloud access, eliminating VPN lag and providing centralized management, global policy control, and real-time analytics. I appreciate its AI-powered SSL inspection, as it effectively scans and detects zero-day threats, transitioning smoothly where traditional filters might miss. The feature that stands out the most for me is the AI-powered SSL inspection, which has turned our biggest security blind spot into our strongest layer of defense. Zscaler's solution allows us to inspect all encrypted traffic without slowing down our bandwidth or forcing hardware upgrades. I also love the scalability since it's cloud-native, and it doesn't require worrying about CPU cycles, whether you have a small or large number of users streaming or downloading heavy data. It makes the VPN experience actually feel faster than being in the office and provides anti-virus engines without the latency that multiple appliances would introduce.

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. Review collected by and hosted on G2.com.
