A monitoring service for certificates, domains, email-security records, and other assets that can expire or break.

Landing page captured for the 2026-10-07 issue.

For: IT teams tracking certificates, domains, and service credentials
Worth noticing: Alerts can be assigned per asset and routed through Slack, Teams, email, or a ticketing webhook at six stated lead times.

Field notes

The public scan uses no-signup access and is estimated at about 30 seconds; enabling live checks requires a DNS ownership record. The service describes pulling issued certificates from Certificate Transparency logs, handshaking live endpoints, and checking email-authentication records, including SPF's 10-lookup limit. Teams can assign an owner to each asset and route alerts at six stated lead times.
