General availability: Application Gateway mutual authentication

Published date: February 22, 2022

Azure Application Gateway is announcing general availability for transport layer security (TLS) mutual authentication. Mutual authentication allows for two-way TLS certificate-based authentication, which allows both client and server to verify each other's identity. This release strengthens your zero trust networking posture and enables many connected devices, IoT, business to business, and API security scenarios.

You can upload multiple client certificate authority (CA) certificate chains on the Application Gateway to use for client authentication. You can also choose to enable frontend mutual authentication at a per-listener level on Application Gateway. We are also adding enhancements to server variables supported on Application Gateway to enable you to pass additional client certificate information to backend as HTTP headers.

With this release we are also extending support for listener specific TLS policies which allows you to configure predefined or custom TLS policies at a per listener granularity, instead of global TLS policies.
