Free SSL Monitoring
The Free SSL Certificate Management Tool
Certooz is TLS certificate management software that monitors every SSL/TLS certificate for you — receive alerts before expiration and avoid downtime across Let’s Encrypt, ZeroSSL, DigiCert, Comodo and other Certificate Authorities.
Expired certificates cause downtime you don’t see coming
Without a certificate manager, renewals are tracked in spreadsheets and forgotten until it’s too late. An expired certificate takes your website offline and triggers browser security warnings for your visitors.
- Unexpected downtime and lost revenue
- “Your connection is not private” browser errors
- Missed renewal deadlines across multiple domains

Certooz is a certificate manager tool that scans your certificates every day and alerts you before they expire — so you fix them on your schedule, not the browser’s.
