Do I need to sign up?

No. The SSL checker is free and works without a Needle account.

Is this a full security audit?

No. It shows certificate metadata and common signals (e.g. HSTS). For compliance or deep testing, use dedicated security tools.

Why was my domain blocked?

We only allow public hostnames. Localhost, private IPs, and malformed domains are rejected to prevent abuse.

Why “Too many requests”?

We rate-limit checks so the tool stays free. Wait a bit and try again.
