Mozilla have put together a tool for testing many areas of SSL security. We’ve recently discussed using the free Let’s Encrypt service to secure your site, but it is also important to ensure the security settings are up to date.
“While we’d love to say that any site that scores an A+ on the Observatory is perfectly secure, there’s a lot more that goes making a website secure than what we can test.” It may not be even possible or wanted to achieve such levels of security as this may make sites unavailable for older devices and compatibility. Particularly HTTP Public Key Pinning, which is targeted specifically towards large and/or sensitive websites and implementing it is considered optional.
That said, this is a fantastic tool and asset from Mozilla.
