    Reviewed on Sep 04, 2026
    Review provided by G2
    What do you like best about the product?
    I love that I never have to manually switch it on or remember any passwords. It starts up silently and keeps everything secure. My internet speed stays solid and never lags, either.
    What do you dislike about the product?
    It sometimes flags harmless work websites, which disrupts my workflow. Then I have to go back and forth with IT/admin to get an exception added. I’d really appreciate an alert that clearly explains why a site was flagged in the first place.
    What problems is the product solving and how is that benefiting you?
    Working securely from anywhere is now possible, be it office or outside office. There is no hassle and work apps load faster and stay connected all the time with no extra effort.

    What do you like best about the product?
    we mostly used it instead of a traditional VPN to connect to the client network. quite simple. just press Connect to connect to the client network, no authentication required. AI chatbot for network connectivity should be given. Pricing is better than others.

    Always Reliable, with Easy Access to Configuration and Connection Controls

    Reviewed on Aug 31, 2026
    Review provided by G2
    What do you like best about the product?
    Never had any real issue with it, always seems to work. Easy to access configuration, view status, and disconnect/reconnect/connect from the app drawer.
    What do you dislike about the product?
    Wish it came with some way to easily create a certificate bundle so that when it swaps a website's cert with its own, all of my software doesn't automatically reject it as untrusted (most languages do not automatically trust Windows system/user certs).
    What problems is the product solving and how is that benefiting you?
    It solves the issue of being able to proxy any website on the internet, block access to certain sites that you don't want accessed in a corporate environment, etc.

    Seamless, Auto-Reconnecting Service for Smooth Work-from-Home Connectivity

    Reviewed on Aug 31, 2026
    Review provided by G2
    What do you like best about the product?
    It provides seamless service without any interruption. Also it gets connected automatically when I switch my network. If I work from home, either from LAN or WiFi, the connection will be smooth always.
    What do you dislike about the product?
    The connection speed matters. I think it reduces the bandwidth of my local broadband speed. If I use Microsoft Teams, the connection is good. But if I try to transfer any big files to the cloud, I face a little slowness.
    What problems is the product solving and how is that benefiting you?
    It connects me to my office network without any additional credentials. If I log in once, it saves the login credentials and uses them whenever needed.

    Simple Reliable and Strong Internet Security for everyday and professional work

    Reviewed on Aug 26, 2026
    Review provided by G2
    What do you like best about the product?
    I mainly use Zscaler Internet Access to securely access the internet and company applications, especially while working remotely or from different networks. I appreciate how it protects my connection, blocks unsafe websites, and simplifies following the company security rules. The thing I like most is that it works quietly in the background, making my experience smooth without complicating things. Once it's set up, I don't have to think much about it while browsing or accessing work resources. It gives me high confidence that the websites or applications I'm using are being checked properly. The biggest value for me is that it doesn't interfere with my normal work, and I can just connect and continue with my tasks. The software handles security with ease and doesn't affect my productivity.
    What do you dislike about the product?
    One thing I feel could be improved is the initial setup. Whenever there is a connection issue, it's not clear every time from the user side what the root cause is, so having clear messages or simple troubleshooting steps would help. I also feel that the application could be a little more user-friendly when it comes to showing the connection status. Sometimes it would be useful to quickly know whether the traffic is being properly secured or if there is some issue with the connection. Another thing is that, depending on the network, I have noticed that the connection can sometimes feel a little slower, especially when switching between different networks. It's not a major problem but it's noticeable during day-to-day work.
    What problems is the product solving and how is that benefiting you?
    I use Zscaler Internet Access to securely access the internet and company applications, protecting my connection and blocking unsafe websites. It simplifies following security rules and makes remote work easier without manual steps. It works quietly, ensuring a smooth experience and high confidence in security.

    Reliable Cloud-Based Security for Enterprise Users

    Reviewed on Aug 26, 2026
    Review provided by G2
    What do you like best about the product?
    From an IT support perspective, I appreciate that Zscaler Internet Access offers centralized control over internet access and security policies. It’s especially helpful for managing users across multiple locations without having to rely entirely on traditional network security setups. Once you get familiar with the logs and how the policy flow works, troubleshooting access and policy-related issues is fairly straightforward as well.
    What do you dislike about the product?
    There’s a bit of a learning curve when you’re first getting familiar with the policies and the troubleshooting process. Some connectivity issues can also take time to investigate, since there may be multiple factors involved, such as endpoint settings, policies, and overall network conditions.
    What problems is the product solving and how is that benefiting you?
    It helps secure users’ internet access no matter where they’re working. From an enterprise IT perspective, having centralized policies makes it easier to manage access, investigate security-related issues, and support remote users without relying entirely on the corporate network.
