Zscaler Internet Access | Security Service Edge (SSE) (2025)

Transform your architecture from firewalls to zero trust

To protect your users, data, apps, and devices, you need a cloud native secure web gateway (SWG) that enables you to:

Traditional firewall-centric architectures don't stop modern threats

Stop advanced attacks and data loss with the leading SSE

A true zero trust proxy architecture inspects 100% of TLS/SSL traffic at scale, with direct user-to-app connections based on identity, context, and business policies.
