SiteCanary monitoring
Detect trust and identity drift
Monitor certificate and server identity changes that ordinary availability checks cannot explain.
What it checks
- TLS chain verification, hostname, protocol, and expiry
- SSH host-key fingerprint and algorithm
- SSH banner, key exchange, cipher, and MAC
When it alerts
- A certificate is invalid, mismatched, or near expiry
- An enabled SSH identity or negotiation value changes
- A TLS or SSH connection cannot be established
What you can investigate
- Certificate verification and expiry details
- Observed SSH identity and negotiation values across runs
