Welcome to CertMS Documentation¶
CertMS is a certificate monitoring platform that automatically discovers, tracks, and alerts your IT team before SSL/TLS certificates expire — across your Windows CAs, Windows servers, Linux servers, and public URLs.

What CertMS Does¶
Certificate outages don't announce themselves. CertMS gives your team full visibility into every certificate across your infrastructure so you can act before something breaks.
- Discovers certificates from Windows Certificate Authorities, Windows and Linux servers, and monitored URLs
- Associates certificates to the servers they're installed on — so you know exactly what's affected when something's about to expire
- Alerts your team via email, help desk ticket, or webhook before expiration windows hit
- Reports on expiring, issued, and revoked certificates on a schedule or on demand
- Documents replacement procedures directly inside CertMS, attached to individual certificates

Why Certificate Monitoring Matters Now¶
The CA/Browser Forum has mandated shorter certificate lifespans across three phases:
| Date | Maximum Certificate Lifespan |
|---|---|
| March 15, 2026 | 200 days |
| March 15, 2027 | 100 days |
| March 15, 2029 | 47 days |
At 47-day lifespans, manual tracking isn't just inefficient — it's operationally impossible at any meaningful scale. CertMS is built for exactly this environment.
