Certificate Monitor: catch expiring SSL/TLS certificates
An expired certificate on a mail server or website causes browser warnings and failed deliveries with no other warning sign. Certificate Monitor watches the dates so you don't have to.
- Where to find it
- Monitoring & Risk → Certificate Monitor
What you'll see per host
- A grade: A, B, C, or red for anything worse.
- The issuer, the protocol and cipher in use, and a validity bar showing how far through its life the certificate is.
- Expiring Soon once fewer than 30 days remain.
- Pending Scan for a host that hasn't finished its first check. A brand-new host never looks expired when it isn't.
Get told before it matters
Create a Cert Expiry alert under Alerting with a threshold of, say, 30 days. DMARCS emails you when any monitored certificate crosses it.
If a certificate shows as expired but you know it's valid, the host may still be in its first scan. Re-run the scan; if it persists, contact support.
