Check your websites security headers with

There are a set of nifty HTTP Headers that you can emit from your site on every response which will harden your site against spoofing, XSS and more

Here at, we have just launched 8 new checks in the snapshot that is taken of your sites over twice a day!

The eight headers we now look for on responses from your site are:

  • Content Security Policy
  • Expect CT
  • Feature Policy (We check you DONT have this deprecated header)
  • Permissions Policy (We check you DO have this new header!)
  • Referrer Policy
  • Strict Transport Security
  • X-Content-Type-Options
  • X-Frame-Options

None of these headers alone will protect your site from compromise – do not be lured into a false sense of security. However it is best practice to LEARN about them, and APPLY them to your site wherever possible to best defend against compromise, clickjacking and XSS.
