Zscaler

Zscaler is a cloud-delivered security platform designed to help organizations implement zero trust architecture and secure access to applications, data, and services from any location. Operating as a secure service edge (SSE) solution, it replaces traditional network perimeter models with user- and application-centric security controls. Its primary purpose is to protect users, workloads, and IoT/OT devices by inspecting traffic in real time and enforcing consistent security policies across distributed environments.

Key capabilities include secure web gateway (SWG), cloud firewall, cloud access security broker (CASB), and data loss prevention (DLP), all delivered as a scalable, multi-tenant cloud service. Zscaler Private Access (ZPA) provides zero trust network access (ZTNA) to internal applications without exposing them to the internet or relying on VPNs, reducing attack surface and lateral movement. The platform also offers advanced threat protection with sandboxing, SSL inspection at scale, and granular policy controls based on user, device posture, and application. Centralized management and analytics provide detailed visibility into traffic, threats, and user activity, enabling faster incident response and compliance reporting.
