Their Pitch
Unleash the Power of Zero Trust + AI
Our Take
It's a cloud security service that sits between your employees and the internet, checking everything they access without needing traditional firewalls or VPNs. Think of it as an invisible bouncer that follows your team everywhere.
Deep Dive & Reality Check
Used For
- +**Your VPN keeps breaking and remote workers can't access internal apps** → Employees get secure access to company tools from anywhere without joining the full network
- +**You're getting hacked through employees clicking bad links** → Every website and download gets scanned before it reaches their computer, blocking malware automatically
- +**Attackers who breach one system spread everywhere** → Each app connection is isolated, so hackers can't move sideways through your network
- +Eliminates firewall ports entirely - everything routes outbound through their cloud, cutting attack surface
- +Works across multiple cloud providers without complex networking setup
Best For
- >Government agencies and large companies tired of VPN headaches for remote workers
- >IT teams managing 500+ employees across multiple locations who need bulletproof compliance
- >Companies that got breached and need to lock down everything without killing productivity
Not For
- -Small teams under 100 people — you're paying enterprise prices for complexity you don't need
- -Privacy-focused companies — it installs root certificates to inspect ALL your encrypted traffic, including personal browsing
- -Anyone wanting something that just works — users report constant 10-minute disconnections that disrupt daily work
Pairs With
- *Salesforce (gets OAuth integration but watch for token breaches that expose your customer data)
- *Google Workspace (for identity management since Zscaler needs to know who's accessing what)
- *Slack (where IT posts about 'planned maintenance' during those random disconnections)
- *AWS/Azure (where you install App Connectors to broker access to your cloud resources)
- *Okta (for single sign-on since users need seamless login despite all the security layers)
- *Splunk (to analyze all that traffic data Zscaler collects from inspecting everything)
The Catch
- !It disconnects and reconnects every 10 minutes and 5 seconds (lasting 6 seconds each time) which drives people insane
- !The root certificate means Zscaler can see everything your employees do online, even on personal sites during work hours
- !Supply chain breaches happen - in 2025 their vendor got hacked and exposed 700+ customer contact lists
Bottom Line
Enterprise security that costs enterprise money and inspects literally everything your employees do online.
