SecurityHeaders.io tries to provide a fair score for all sites that are analyzed and the score is representative of how many security-based HTTP response headers the site issues. Over an HTTP connection, it checks for Content-Security-Policy, X-Content-Type-Options, X-Frame-Options and X-XSS-Protection. Over an HTTPS connection, it checks for two additional headers which are Strict-Transport-Security and Public-Key-Pins. And, ahem… it looks like our own site got an A+ rating; check for yourselves here.
