Introducing the MDN HTTP Observatory | MDN Blog

In its lifespan, Mozilla’s HTTP Observatory tool has scanned over 6.9 million websites, providing useful, actionable insights into how developers can improve web security and guard their sites against would-be attackers.

The HTTP Observatory tests website compliance with security best practices, mainly concerning the correct usage of HTTP headers. When a scan is complete, it provides a report to tell the user how well their site is doing, with an overall score and grade, and links to documentation explaining what they need to do to improve their security.

Today, we are delighted to announce that the HTTP Observatory’s new home is MDN! This blog post explains a little bit of the history behind the tool, how we got to where we are now, what the migration means for Observatory and MDN, and what Observatory tests.
