My biggest issue with Zscaler is how much it gets in the way of daily coding workflows. Because of how it inspects traffic, tools like Docker, Git, and npm constantly throw SSL certificate errors until I manually fix them. Plus, it noticeably slows down my connection when pulling or pushing large builds. Review collected by and hosted on G2.com.

Zscaler Internet Access is a modern cloud based security service which eliminates the use of old traditional hardware web proxies and firewalls.

It has a network latency which leads into the performance issue as well. Many times it automatically disconnects or start retrying which cause the internet access up and down and creates problem while working or your call get disconnected because of this zscaler behaviour.

I'm not an admin, just a regular user, but Zscaler has honestly changed how my team plans video shoots. We use it to connect to wifi-enabled devices in our video production studio, stuff that's only accessible on the local network. Because it puts all our devices on the same network even when we're fully remote, we can adjust lighting and update TV content through BrightSign's BrightAuthor Connected without anyone needing to physically be in the studio. That's saved us real money too, since we're not paying for separate cloud subscriptions just to get remote access to gear that should just be reachable over the network anyway.

Really the only thing I've run into is having to reconnect manually every once in a while. It's not a big deal, just a small hiccup compared to how much time and money it's saved us on the remote studio access side. Review collected by and hosted on G2.com.

What I like best about Zscaler Internet Access is how it keeps secure access simple and fast. Rather than relying on traditional VPNs or firewalls that can slow everything down, Zscaler automatically routes my traffic through the nearest cloud data center. As a result, applications like Microsoft Teams, Zoom, and Office 365 run smoothly, while threats such as phishing sites and malware are blocked before they ever reach my device. Overall, it gives me confidence that security is always on, without adding extra steps or causing delays. Review collected by and hosted on G2.com.

What I dislike about Zscaler Internet Access is that the initial setup and policy configuration can be complex, especially for new users. The dashboard has a steep learning curve, and sometimes performance varies depending on the region — we’ve noticed occasional latency when traffic is routed through distant data centers. Pricing can also feel high compared to traditional solutions, and advanced features often require additional licensing. While the platform is powerful, these challenges make onboarding and fine‑tuning more time‑consuming than expected. Review collected by and hosted on G2.com.

What I like least about Zscaler Internet Access are the incorrect blocking of sites and applications. On some occasions, they interrupt daily work and affect productivity.

Zscaler Internet Access is reliable, but sometimes it can slow down access to certain websites or cloud applications because of security inspections. There are also occasions when legitimate websites are blocked, requiring additional approval from the IT team. When working remotely, connectivity issues can occasionally require reconnecting or restarting the client, which interrupts the workflow. Review collected by and hosted on G2.com.

Over the years, we’ve used several secure access solutions for our business, and Zscaler stands out as one of the best for securing internet traffic, whether users are on the LAN or connected via VPN. The UI is friendly and straightforward, making it easy for all our end users to navigate. We’ve been able to get strong value from features like Secure DNS, DLP (Data Loss Prevention), Secure Browsing, and Cloud Sandboxing. Review collected by and hosted on G2.com.

Not a major flaw - but we noticed that switching between multiple VPN networks can be cumbersome while Zscaler internet access is enabled. Custom applications using custom encryption might fail to work unless exceptions/exclusions are configured. Pricing is premium! Review collected by and hosted on G2.com.

The features can make the security management efficient and help the remote as well as office employees. In general, the integration of complimentary internet security functionalities in one single solution is commendable. Review collected by and hosted on G2.com.

Zscaler Internet Access is a nice Internet security tool. But it can take a while to know how everything works. Especially when creating policies for the first time. Overcoming connection issues or blocked websites can be a frustrating experience sometimes. I would like a simpler initial setup process and clearer guides that would allow users to troubleshoot common issues more effectively. Review collected by and hosted on G2.com.
