Why SSL expiry monitoring matters
When a TLS certificate expires, browsers show scary warnings or block the page. Customers bounce. Payment forms fail. SEO takes a hit. The fix is usually a five-minute renew — if someone notices before the clock hits zero.
Most outages are not exotic zero-days. They are calendar failures: a Let’s Encrypt cert that was “set and forget,” a client site nobody logged into for months, a staging host that suddenly became production.
Who gets burned
- Freelancers who maintain a handful of client domains and cannot babysit every panel.
- Tiny agencies where renewals live in one person’s head until vacation.
- Solo operators who automated issuance once and never added an alert.
What “good enough” looks like
You do not need a full observability stack. You need: a list of hostnames, a daily check, and an email when days-left crosses 30, 14, 7, and 1. That is enough time to renew without a fire drill.
Expiry Watch does that for free on up to three hosts. Pro watches 25 hosts for $9/mo.
