Zscaler is the leading zero trust cloud security platform — replacing traditional VPN and network perimeter security with a cloud-native security model where user identity and context determine access rather than network location. Zero Trust Exchange is Zscaler's cloud security fabric — traffic from users, devices, and workloads is routed through Zscaler's 150+ data centre locations globally for security inspection before reaching the destination. Zscaler Internet Access (ZIA) provides secure web gateway functionality — scanning all internet traffic for malware, blocking policy violations, enforcing DLP (Data Loss Prevention), and providing visibility into user internet usage. Zscaler Private Access (ZPA) replaces VPN — providing application-level access to internal applications without connecting users to the corporate network, eliminating lateral movement risk. AI threat prevention in Zscaler includes AI-powered malware detection, AI-driven policy recommendations, and AI anomaly detection identifying unusual user behaviour that may indicate account compromise. Generative AI controls in Zscaler allow organisations to manage employee access to AI tools — controlling which AI services can be accessed, monitoring prompts sent to external AI services, and preventing sensitive data from being shared with AI models. SASE (Secure Access Service Edge) combines networking (SD-WAN) and security in one cloud service. With Fortune 500 enterprise deployment and government customers, Zscaler validates as a leading zero trust security platform.
Zscaler AI runs as ml platform software built around data and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, api, and endpoint agent.
The capabilities that matter most for teams evaluating Zscaler AI.
ML malware detection and behaviour analytics identifying unusual patterns indicating account compromise — proactive threat identification beyond signature-based detection.
Application-level access without corporate network connection — eliminating lateral movement risk that traditional VPN creates when compromised users access the full network.
Managing employee AI tool access and preventing sensitive data sharing with external AI services — emerging enterprise governance for the AI tool adoption wave.
