Overview
Zscaler Internet Access, commonly called ZIA, is a cloud-delivered Security Service Edge platform. It provides controlled access to internet and SaaS applications from offices, home networks and mobile locations.
ZIA operates as an inline security gateway. Traffic is forwarded to a Zscaler service edge, where policies can inspect content, identify threats and control application use. The service is designed to reduce dependence on appliance-based web gateways and perimeter firewalls.
The platform is primarily intended for enterprise security, networking and IT operations teams. Zscaler positions ZIA for hybrid workforces, branch locations and organizations modernizing direct-to-cloud connectivity.
