Zscaler Internet Access

Zscaler Internet Access is a cloud-native Security Service Edge and Secure Access Service Edge solution designed to deliver secure, fast, and policy-driven internet and SaaS access to distributed enterprise workforces. Acting as an intelligent security stack in the cloud, it replaces traditional perimeter hardware by inspecting all outbound user traffic inline, providing deep packet inspection, URL filtering, advanced threat protection, cloud sandboxing, and data loss prevention without backhauling traffic over expensive MPLS circuits.

Operating across hundreds of Zscaler data centers globally, the service terminates user connections locally to enforce comprehensive security policies while providing single-digit millisecond latency to cloud applications. It integrates natively with enterprise identity providers like Microsoft Entra ID and Okta, leading endpoint security solutions, and enterprise SIEM/SOAR platforms to deliver context-aware policy enforcement and centralized logging. Core enterprise use cases include protecting distributed workforces from ransomware and phishing attacks, enabling direct-to-cloud branch connectivity, enforcing corporate web acceptable use policies, and securing unmanaged internet traffic.

With Zscaler Internet Access, organizations transition from complex, hardware-bound network security architectures to an agile cloud-native framework that scales elastically with business demand. Security operations teams gain complete visibility into all web and cloud traffic, including full TLS decryption, accelerating threat detection and incident response workflows. The platform lowers capital expenditures, simplifies global IT administration, and provides robust cyber defense across modern distributed enterprises.
