SSL Alerts watches every certificate you care about — public domains and internal ones you paste in — checks them daily, and emails you before anything breaks. No dashboards to babysit, no surprise "not secure" warnings.
Three steps, and you're covered — no agents to install, nothing to maintain.
A domain we check live over TLS, or an internal PEM you paste in directly.
A real handshake each day, plus a faster recheck the moment something looks off.
Email alerts at 30/14/7/1 days out — and repeated every 30 minutes if it goes critical.
One list, colour-coded by urgency, filterable by group or status. No training required — if you can read a traffic light, you can read this dashboard.
Try it freeEvery check runs automatically in the background. You only hear from us when a certificate actually needs attention.
Every domain on your list is checked once a day, straight from a live TLS handshake — the same thing a visitor's browser sees.
Email alerts fire at the thresholds that matter, once each — so you get warned early without being spammed daily.
See who issued each certificate, when it was issued, and exactly how many days remain — at a glance, for every domain.
Got certs we can't reach — internal CAs, air-gapped services, staging behind a VPN? Paste the PEM and we'll track its expiry the same way.
Sort certificates into groups by client, environment or team, then filter to see just what's healthy, expiring or critical in each.
Once something goes critical, we re-alert every 30 minutes until you acknowledge it — so it can't quietly slip past you.
Start free with 1 certificate. Public domains and internal certs both count the same. Upgrade whenever you outgrow your plan — no contracts.
The short version — the full documentation covers everything else.
No. We connect the same way a visitor's browser does, read the certificate, disconnect. Nothing installed.
No — only when something actually needs attention, and repeats stop the moment you acknowledge it.
Paste the PEM directly. We track its expiry without needing a live connection at all.
Your account reverts to the free tier's limit and monitoring pauses — nothing gets deleted.
