Strict Transport Security

Last updated on : 2023-03-20

Note:

Strict Transport Security shows a browser compatibility score of 97. This is a collective score out of 100 to represent browser support of a web technology. The higher this score is, the greater is the browser compatibility. The browser compatibility score is not a 100% reflection for every browser and the web technology support. However, it does give you an estimate on how much you should rely on a particular web technology in terms of browser compatibility.

Overview

This message appears because this site is only accessible over a secure connection HTTPS.
