Zscaler
Vendor & Platform Overview
Zscaler operates the world's largest inline security cloud, processing hundreds of billions of daily transactions to protect thousands of enterprise organizations. Through its flagship Zero Trust Exchange, Zscaler decouples user access from enterprise networks, connecting authenticated users directly to specific private applications without placing them on the corporate network, rendering enterprise infrastructure invisible to external reconnaissance.
Architecture & Detection Telemetry
The Zscaler Zero Trust Exchange functions as an intelligent, high-speed inline proxy distributed across more than 150 global data centers. Traffic generated by endpoints running the Zscaler Client Connector is encrypted and routed to the nearest cloud edge, where Zscaler Internet Access (ZIA) performs full TLS/SSL inspection, URL filtering, cloud sandboxing, and DNS proxying, while Zscaler Private Access (ZPA) establishes outbound-only micro-tunnels to corporate applications.

Frequently Asked Questions
How does Zscaler prevent lateral movement during a ransomware outbreak?
Traditional VPNs place users directly on the enterprise network, enabling lateral propagation. Zscaler connects users only to individual authorized applications via outbound micro-tunnels, making network scanning, SMB worming, and lateral reconnaissance technically impossible.
Can Zscaler inspect encrypted HTTPS traffic at enterprise scale?
Yes. The Zscaler Zero Trust Exchange performs full, line-rate SSL/TLS inspection without performance degradation or appliance bottlenecks, terminating encrypted sessions at cloud edge to inspect payloads for concealed threats.
What is the difference between ZIA and ZPA?
Zscaler Internet Access (ZIA) secures outbound user traffic to the public internet, SaaS platforms, and cloud applications, while Zscaler Private Access (ZPA) delivers Zero Trust Network Access (ZTNA) to internal, private applications hosted in data centers or private clouds.
