First of all, thanks for sharing, I didn&#x27;t know about many of these headers!<p>From recent scans I see that www.google.com got an E with missing headers:<p><pre><code>    Strict-Transport-Security
    Content-Security-Policy
    Public-Key-Pins
    X-Content-Type-Options
</code></pre>
Is this negligence on Google&#x27;s part or ...?
