FAQ
Why did my SSL score drop?
Common causes include an expiring certificate, legacy TLS protocols enabled, weak cipher suites negotiated, HSTS removed or server handshake failures. The "Score change insights" section below lists the specific reason for each move.
How often is the score updated?
Watched domains are scanned daily; leaderboard domains get weekly full snapshots. Publicly queried domains append history snapshots under throttling, building an auditable score history.
Does certificate rotation affect the score?
Usually not — normal rotation keeps the score unchanged, unless the new certificate changes key strength, issuing CA or signature algorithm. The insights section flags such events.
How can I improve my SSL score?
Enable TLS 1.3, disable TLS 1.0/1.1, use strong cipher suites (AES-GCM / ChaCha20), deploy HSTS correctly, and keep the certificate valid with sufficient key strength (RSA >= 2048 or ECC >= 256).
