There are a couple easy ways to check if the HSTS is working on your WordPress site. You can launch Google Chrome Devtools, click into the “Network” tab and look at the headers tab. As you can see below on our Kinsta website the HSTS value: “strict-transport-security: max-age=31536000” is being applied.

If a website declares an HSTS policy, the browser must refuse all HTTP connections and prevent users from accepting insecure SSL certificates. HSTS is currently supported by most major browsers (only some mobile browsers fail to use it).
