Confirm TLS 1.2 Protocols are Enabled

There are several options to test your site for TLS 1.2 Protocols.

Option 1: Use SSL Labs for external testing

To quickly test external facing servers, it’s possible to use the free online service from Qualys SSL Labs. This free online service performs a deep analysis of the configuration of any SSL web server on the public Internet.  https://www.ssllabs.com/ssltest/index.html

Option 2: Use SSLyze for internal testing

SSLyze is a Python library and a CLI tool that can analyze the SSL configuration of a server by connecting to it. It is designed to be fast and comprehensive and should help organizations and testers identify mis-configurations affecting their SSL/TLS servers.
