Why it matters

An expired cert is a 100% outage — self-inflicted.

When a certificate lapses, browsers don't degrade gracefully. They block the page with a red interstitial that says your site isn't safe. Conversions go to zero, search crawlers back off, and the fix — renew and deploy — takes longer under pressure. Auto-renewal helps, but it fails quietly more often than teams expect: a cron that stopped, a DNS change, a renewal that needed a manual step.

The only reliable safety net is an independent watcher that checks the certificate from the outside and tells you before it expires.

What UptimeClaw watches

SSL monitoring runs alongside your uptime checks — one monitor, both jobs.

Expiry

Tiered advance alerts

Get warned 30, 14, and 7 days before a certificate expires — enough lead time to renew calmly, not at 2 a.m.

Validity

Chain & hostname checks

Catch misissued, mismatched, or untrusted certificates — not just expiry. A cert that doesn't match the hostname fails users the same way.

Channels

Alerts where you'll see them

SSL warnings go to the same channels as your downtime alerts: WhatsApp, email, Slack, webhooks — your choice.

SSL monitoring FAQ

How far ahead do I get warned?

At 30, 14, and 7 days before expiry — tiered so an early heads-up doesn't get ignored and a final reminder still lands in time.

Isn't auto-renewal enough?

Usually — until it isn't. Renewals fail silently more often than teams expect. An independent external check is the backstop that catches the failure auto-renewal didn't report.

Do I need a separate monitor for SSL?

No. SSL tracking runs alongside the HTTP(S) monitor you already have on a site — no extra setup.

Can I get SSL alerts on WhatsApp?

Yes — SSL alerts use the same channels as downtime alerts, including WhatsApp, which is included on every plan (even free).
