Mozilla launches free website security scanning service
In order to help webmasters better protect their websites and users, Mozilla has built an online scanner that can check if web servers have the best security settings in place.
Dubbed Observatory, the tool was initially built for in-house use by Mozilla security engineer April King, who was then encouraged to expand it and make it available to the whole world.
She took inspiration from the SSL Server Test from Qualys’ SSL Labs, a widely appreciated scanner that rates a website’s SSL/TLS configuration and highlights potential weaknesses. Like Qualys’ scanner, Observatory uses a scoring system from 0 to 100 — with the possibility of extra bonus points — which translates into grades from F to A+.
