SSL Monitoring
An expired SSL certificate turns a working site into a full-screen browser warning within seconds, and it's one of the most preventable outages there is — certificates expire on a known schedule, not randomly.
The failure mode is almost always the same: a certificate auto-renews everywhere except one subdomain, a client changes hosts and drops auto-renewal, or a renewal reminder goes to an inbox nobody checks anymore. Tracking expiry across every hostname (not just the root domain) closes that gap.
Who this is for
- Agencies managing SSL across many client domains and subdomains
- Freelancers who don't want a certificate warning to be how a client finds out something's wrong
- Anyone who has been surprised by a expired-certificate warning before
