Self-Assessment

SSL Health Check

Check what's actually true of your setup today. Nothing here is tested against a live server — this is a self-assessment, not a scan — and nothing you check is sent anywhere.

Certificate renews automatically

No manual steps — a cron job, systemd timer, or your host's built-in automation handles it.

HSTS is enabled

Your server sends the Strict-Transport-Security header, not just a redirect.

All HTTP traffic redirects to HTTPS

Every entry point — not just the homepage — forces the secure version.

Checked for mixed content warnings

No HTTP resources loading on your HTTPS pages.

OCSP stapling is configured

Your server proactively includes its own revocation status in the handshake.

You know exactly when your certificate expires

Not "probably fine" — an actual date you can name, or active monitoring.

Server only accepts TLS 1.2 and 1.3

TLS 1.0 and 1.1 are disabled — both are formally deprecated.

A CAA record is set for your domain

Names exactly which CA is authorized to issue for your domain.

Certificate covers every subdomain you actually use

No subdomain is quietly running without its own valid coverage.

You have a plan for a compromised private key

Not just "we'd figure it out" — an actual known first step.
