mutual tls

This tag collects WindowsForum.com discussion of mutual TLS as a practical configuration and architecture topic, centered on Microsoft cloud services. The current coverage focuses on Azure Front Door Premium, where mutual TLS authentication reached general availability and lets administrators require and validate client certificates at Microsoft's edge before requests reach an application's origin. The discussion highlights an important boundary: this authenticates client-to-Front Door connections rather than the separate Front Door-to-origin connection, so it should not be mistaken for uninterrupted mutual TLS from client to application. Readers interested in certificate validation, tier differences, and origin security will find the most relevant material here.
