Auth doesn’t work
Auth steps keeps downloading sso files that does nothing. Can’t use the app!
Snail phase in action
The application, which is intended to secure the communication channel, unfortunately makes user authentication quite difficult, particularly when the user is engaged in a time-bound task. Repeated authentication failures significantly delay access to the secured channel and affect the overall user experience.
It is requested that the concerned team may kindly review and fine-tune the authentication mechanism to ensure more reliable and seamless login verification, particularly for time-sensitive operations.

Erratic
It need a big update, it can’t drain the battery this fast plus how it fails to connect multiple times, with my 17 pro max is a nightmare, with my 12 pro max works better.
Works well
No issues observed
Works great now a days
All previous issues have been addressed
GSK
My IPhone started behaving erratically after installing this app. IPhone’s battery is draining very fast and restarting frequently. It needs an update.
Too many conflicts
This vpn causes CarPlay to crash and conflicts with many other apps. Sunbelt needs to drop this app
Drains battery
Zcaler consumes way too much battery in the background especially using on the iPhone air. I have had to disable it. Can the developers look into this battery drain, most of my friends also have this same issue.
Battery hogging
It running in background all the time, and consuming battery. For older devices it is nightmare.
Fantastic work
Although older versions had flaws, the latest version is superb and runs seemlessly with minimal battery consumption, no lag on wake up and no issues I’m aware of. Great work Zscaler.
Good mobile implementation of the ZCC
Works very well. Similar experience to the desktop client.
Can’t turn off VPN
There’s no clarification on how I can stop the vpn, very shoddy UI
Client connects / disconnects often - local servers throttle traffic - since Aug 2025
Client connects / disconnects often - local servers throttle traffic - since Aug 2025 - changed providers and countries even from Canada to US - nothing changed.
App is fine - backend needs to be looked at.

The Glacial Guardian of Your Data (and Battery)
If you've ever wanted to experience what it's like to browse the internet through a melting glacier, zScaler is the perfect app for you. Imagine a security solution so committed to safety, it slows your connection down to pre-broadband speeds — just to make sure every packet gets a proper pat-down by digital customs.
Speed
Let’s address the frozen elephant in the room: performance. zScaler operates at the speed of trust… which apparently is slower than erosion. Opening a webpage feels like watching continental drift — fascinating in theory, excruciating in practice. Need to quickly check your email? Better send a carrier pigeon, it’ll get there faster.
Privacy
Installing zScaler on your phone is like inviting a mall security guard to live in your house. Yes, they’ll watch over things — but they’ll also go through your fridge, read your texts, and maybe take notes on your playlists. Full device VPN? Sure. Certificate installation? Why not. SSL inspection? Of course. At this point, it’s unclear who the client is protecting you from — but it’s definitely not itself.
Battery Life
While zScaler claims to keep your phone secure, it also helps you disconnect... permanently, by draining your battery faster than Instagram on a 5G loop. One moment you’re sending a WhatsApp message, and the next you’re frantically searching for an outlet in a coffee shop to charge your phone.
Final Thoughts
If you enjoy slow connections, questionable privacy trade-offs, and having your phone run hotter than your firewall logs — then zScaler is the tool for you. It's like carrying an overzealous IT auditor in your pocket, complete with a clipboard and a deep mistrust of your DNS queries.

Terrible
Always asking to re-authenticate and doesn’t let you.
Disconnected but says connected
Why does it constantly say it’s connected when in fact it’s disconnected?
Bug regarding on and off
VPN is not turning off despite turning it off from the control Centre, it automatically reconnect somehow, so I always have to go back to the app and log so that I am not accessing personal things on company’s VPN
complicated and bad
very complicated. It makes my connection unstable and also I feel like hacked into my phone:)
