CertMon actively monitors deployed TLS/SSL X.509 certificates for expiration, availability, and compliance. As a Microsoft Teams enterprise assistance Bot, CertMon actively connects to your hosts and verifies server certificates. Configure the Bot using natural language commands and it will send you reminders when certificates are near expiration, become invalid, or inaccessible. CertMon can also provide a detailed report for use by compliance/governance and operations/site-reliability. Report is available as a Microsoft Excel worksheet, containing connection and certificate details.
