I mostly like Zscaler Internet Access for its secure internet access, cloud architecture, web filter, and its ability to block phishing attacks. The web filtering capabilities allow us to enforce corporate internet usage policies, while the cloud-based architecture simplifies administration, improves availability, and can be used on a large number of devices and users. Also, the installation process was easy and quick, taking only 2-3 minutes. Review collected by and hosted on G2.com.

I find that my devices sometimes work slow, especially on older systems, which can be a bit frustrating. I also experience temporary access issues during policy changes that need adjustments, which can be inconvenient. Review collected by and hosted on G2.com.

Sometimes web filtering is too strict and blocks safe websites. Improving policy flexibility and troubleshooting would make it even better. Review collected by and hosted on G2.com.

While Zscaler Internet Access provides strong security, troubleshooting connectivity issues can sometimes be challenging, and occasional policy restrictions or website blocks may impact the user experience. Review collected by and hosted on G2.com.

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.

My company uses this for every laptop as a layer of security when accessing the internet and files from home. This is seamless and does not interfere with my access to the items I need to do my job efficiently. a prompt will come up every once in a while but in general I don't have to think about it.

It's something i use for work only, its quite effective at keeping popups to a minimum but also restricts access to things and will have certain parts of webpages blanked out due to its blocking activity. Review collected by and hosted on G2.com.

Random parts of ads or such on pages i scroll will be blanked out or have a huge "cannot display this content" on a grey background. I'd prefer if it just blurred or something else, because the greyed out portion makes it hard to read everything else sometimes. Review collected by and hosted on G2.com.
