Front Door minimum TLS#
Front Door should reject TLS versions older then 1.2.
The minimum version of TLS that Azure Front Door accepts is configurable. Older TLS versions are no longer considered secure by industry standards, such as PCI DSS.
Front Door lets you disable outdated protocols and enforce TLS 1.2. By default, a minimum of TLS 1.2 is enforced.
Consider configuring the minimum supported TLS version to be 1.2.
