Zscaler SSL Inspection

Stop hidden threats at speed and scale


Visibility is the cornerstone of zero trust security

Over 95% of web traffic and 85% of attacks utilize encrypted channels such as TLS/SSL. Appliance-based security solutions can’t inspect this traffic at scale without encountering performance and capacity limitations. The result? Security teams let traffic pass through uninspected—opening their organization up to increased risk.


The cloud native Zscaler Zero Trust Exchange™ enables complete TLS/SSL inspection at scale, without latency. This visibility powers advanced security, dynamic access control, and data protection, ensuring your data stays in and attacks stay out.


Unlimited capacity

Inspect 100% of your users’ TLS/SSL traffic, on or off-network, without performance concerns. Our service elastically scales based on your traffic demands.

Leaner administration

Certificates are uploaded once to the Zscaler cloud and are then available in all 150 data centers worldwide. No more managing certificates individually across all gateways.

Granular policy control

Ensure compliance by excluding encrypted user traffic for website categories such as healthcare or banking.

Enhanced security

Ensure support for the latest AES/GCM and DHE codes for PFS. User data is never stored in the cloud.

Simplified cert management

Use our certificates or bring your own. Use our API to easily rotate your certificates as often as you want.


Embrace the ultimate security stack as a service

Zscaler provides a full security stack as a cloud service to deliver all the in-depth protection you’ll ever need, with full inbound/outbound content analysis and unlimited capacity to inspect all your traffic, including TLS/SSL. Every user, no matter where they connect from—on- or off-network—gets the same protection.
