It protects me from random links and phishing attempts sent to my work mail. it creates a sandbox for me to test all types of links. As an IT admin it helps me safeguard the confidential data
What do you dislike about the product?
I get around 0 to 50 ms of added latency which causes a noticeable lag for when me and my team are far away from a Zscaler node. I have also noted an overall 10% to 20% drop in upload and download speeds when routing their internet traffic through the Zscaler enforcement nodes
What problems is the product solving and how is that benefiting you?
I had experience with legacy architectures which used to force remote employees like me to log into a corporate VPN to route traffic back to an office firewall.Zscaler eliminates this which allowis remote users like me to safely connect directly to the internet and SaaS applications.

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.

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.

Reviewed on Aug 31, 2026
Review provided by G2

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.

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.
