Vulnerability scanning.
The checker now tests for Heartbleed, BEAST, POODLE, ROBOT, and Ticketbleed.
These are TLS attacks that a valid certificate won't protect you from. Now you'll know if your server is exposed.
Every scan now returns a security grade from A to F.
It breaks the score down by certificate validity, trust chain, protocol support, cipher strength, and known vulnerabilities.
You see exactly which factors helped or hurt the grade.
