FAQ
How do I get an A+ rating?
Enable TLS 1.3 with strong ciphers, ensure full forward secrecy (PFS), deploy HSTS correctly, and use a valid certificate from a trusted CA.
Why is my score low even with a valid certificate?
The score evaluates the whole TLS configuration — legacy protocols, weak ciphers or missing HSTS all reduce it.
