Why Bitbucket security headers matter

Security headers tell browsers how to protect visitors on bitbucket.org against clickjacking, MIME sniffing, XSS, and protocol downgrade. A strong grade (A/A+) means the service ships a modern security posture; a weak grade means important protections are missing.
