Zscaler

At the core of the Zscaler platform is the Zero Trust Exchange, an inline security cloud that enforces identity- and context-based policy on every connection instead of relying on network trust. Every capability runs on this same architecture and shares the same real-time data and signals. Traffic is fully inspected, including encrypted traffic, without the performance trade-offs of traditional appliances.

In practice, the Exchange works in three steps: it verifies identity and device posture on every connection, inspects all traffic in real time, and connects each user or workload only to the specific app or resource it is authorized to reach, with no direct network access and no lateral movement.

1. Secure Private Access (ZPA): Delivers zero trust network access (ZTNA) to private applications without VPN complexity or public internet exposure. ZPA brokers direct, one-to-one connections between authorized users and specific apps, so users never touch the corporate network and applications are never exposed to the internet;
   ​
2. Secure Internet Access (ZIA): Secures all internet and SaaS traffic through a cloud-native, AI-powered security service edge (SSE). Full inline inspection of encrypted (TLS/SSL) traffic stops advanced threats and prevents data loss, without the need for on-premises hardware.
