    Secure, Reliable Internet Access with Simple Cloud-Based Security

    Reviewed on Aug 13, 2026
    Review provided by G2
    What do you like best about the product?
    I liked that it provides secure, reliable internet access without feeling overly complex. The cloud-based security approach also makes it straightforward to apply consistent security policies across different users and locations.

    I used it regularly to access the internet from various places, and the cloud-based security model meant I didn’t have to depend as much on traditional network infrastructure or spend time manually managing security settings.

    The biggest workflow improvement for me was the consistency. Security policies were enforced no matter where I was working, which made remote work easier and more predictable.

    One unexpected benefit was how much simpler it was to maintain a consistent security experience across users and devices. Overall, it strikes a good balance between security, flexibility and ease of management.
    What do you dislike about the product?
    One area that could be improved is the troubleshooting experience when access to a website or application is blocked. At times, it’s hard to tell exactly what triggered the block or what specific steps are needed to fix it. More detailed, user-friendly explanations, along with clearer guidance on next actions, would make troubleshooting much faster.

    I’ve also noticed that policy changes and configuration updates can occasionally take some digging before their impact is fully clear.

    Lastly, the reporting and dashboard experience could be more intuitive. More customizable dashboards, plus an easier way to drill down from a high-level alert into the underlying traffic, would make the platform more efficient to use.

    Reviewed on Aug 11, 2026
    Review provided by G2
    What do you like best about the product?
    Frm my experience, I'd say the best part of zscaler internet access is that it's ease of use. Once it is active, it runs in the background & provides a secure access to websites and Applications in my work pc. As an end user I don't need to manage complex settings, which makes it's convenient.
    What do you dislike about the product?
    Zscaler works generally well in background, but the application provides a very little to no information when a website is restricted or a connection fails. I may like if more detailed notification and simple troubleshooting guide help users understand the issue well, before reaching to IT support.
    What problems is the product solving and how is that benefiting you?
    This application helps protect my work pc every time by securing Internet & cloud applications access N blocking potential unsafe traffic. On this note, benefits me to use websites work applications securely without needing to manage complicated security settings.
