Domain & DNS
SSL monitoring that warns you before the cert expires.
Relvato checks your HTTPS certificate is valid, trusted, and matches your domain, and alerts you well before it lapses. No plugin — works on any site.

Add your URL and this monitor runs from the outside, the way a visitor sees your site.
What it checks
- ✓The certificate is valid and trusted
- ✓It matches your domain
- ✓Days-to-expiry is above your threshold
- ✓HTTPS negotiates without errors
Why it matters
An expired certificate turns your whole site into a red ‘Not secure’ warning in every browser — and it always seems to happen on a weekend. Relvato gives you days of lead time, so a renewal is a calendar item, not an emergency.
How it works
- Reads the live certificate over a real TLS handshake and validates the chain and the hostname match.
- You set the expiry lead time — say 14 days — and Relvato warns while there’s still time to renew.
- Catches an expired, self-signed, or mismatched certificate: the exact causes of a browser ‘Not secure’ block.
Questions, answered
