Cover every endpoint
Monitor cert expiry for APIs, landing pages, and third party domains.
Check OCSP status and chain completeness, not just dates.
Automate renewals
Alert on failures in ACME flows and renewal scripts.
Test staging certs before rolling into production.
TLS pitfalls
- Wildcard misconfigurations
- Old cipher suites
- Forgotten internal domains
Communicate safely
When certs fail, publish clear status updates with expected fix time.
Share root cause in follow ups to rebuild trust.
TLS outages hit conversion immediately; treat them like full downtime.
