Expiry date
See the expiry from the latest certificate observation and receive warning alerts before that observed date.
SSL/TLS monitoring
SSL certificate monitoring that warns before expiry
Track TLS certificate expiry, issuer, chain, and grade from outside your network, with alerts before the observed certificate lapses.
One website free. No card. Nothing to install.
Issuer and chain
Review the certificate issuer and chain OrionCMD can see from outside your network.
TLS grade
Protocols, ciphers, and chain analysis contribute to an A+ through F grade.
Certificate changes
See when a certificate is replaced so a routine renewal is recorded instead of disappearing into history.
Outside-in evidence
Checks use the public endpoint, so the result reflects the certificate visitors are being served.
Plain-English context
Alerts explain the observed problem and what to review instead of leaving you with only an error code.
See the certificate your visitors see
OrionCMD reads the certificate presented by your public website. The latest observation records its expiry, issuer, chain, and TLS grade, giving you one place to review certificate health alongside uptime and domain monitoring.
Expiry alerts provide time to inspect renewal before browsers start showing certificate warnings. OrionCMD reports the certificate it observed; it cannot guarantee that an automated renewal will complete or that an alert destination will accept every message.
SSL/TLS expiry and grading are included on the Free plan for one website. Standard and Pro add more websites and broader monitoring.
