Certificate automation by the job you actually have
Certificate automation fails in different places depending on who you are. These pages are operating manuals, not persona flyers. Each one is researched against current CA/Browser Forum dates and the APIs this product actually exposes.
Certificate lifetimes are getting shorter. Manual workflows are not.
From 15 March 2026, publicly trusted TLS certificates may be valid at most 200 days. From 15 March 2027, 100 days. From 15 March 2029, 47 days. Domain validation reuse shrinks on the same dates. That schedule is in the CA/Browser Forum Baseline Requirements — not a vendor slogan. Pick the page that matches the work you already do.
SaaS Platforms
Customers type their own hostname. You inherit ownership proof, DNS failures, issuance, renewal and support.
Hosting Providers
A certificate in the panel store is not a live HTTPS site. Deploy, bind, reload, verify, then keep a rollback.
MSPs
PSA reminders track a date. They do not isolate customers, deploy a replacement, or tell you which client will page you Friday night.
Agencies
Launching the site made you the default owner of DNS and TLS. Renewals should not reopen the project.
Developers & Platform Teams
Every service that speaks ACME owns retries, rate limits and inventory. Call lifecycle primitives instead.
Enterprise IT & Security
Spreadsheets list the certificates you remember. Outages come from the ones nobody listed.
