A spreadsheet is not a monitoring system
When you have certificates across many sites and hosts, a spreadsheet goes stale the moment you close it. SSLCanary keeps one live list of every certificate, checks each one for you, and warns you before any deadline — no manual updates.
Many certificates, three steps
- 1
Import your whole list
Paste your whole list, or import a CSV, Excel, or ODS file, or a public Google Sheet — and monitor every SSL certificate at once.
- 2
We de-dup and sort
We validate and de-duplicate on import, then line every certificate up in one dashboard sorted by soonest to expire — no duplicate checks.
- 3
One heads-up stream
Get one plain-English warning at 30, 14, 7, and 1 days before anything in the list expires — across email, Slack, Teams, and more.
Bulk SSL certificate monitoring at scale
When you need to monitor multiple SSL certificates, a spreadsheet and a row of registrar control panels stop working fast. Certificates now renew every few months, so a list you update by hand is stale within days, and once you're tracking many SSL certificates at once, no single control panel shows them all. Bulk SSL certificate monitoring exists because scale, not one certificate, is the real problem.
SSLCanary makes it manageable: import your whole list in one paste, CSV, Excel, or Google Sheet, and it de-duplicates and sorts every certificate by soonest to expire. Structural de-dup keeps hundreds of hosts from firing duplicate lookups or alerts, and a REST API on the Scale and Business plans drives monitoring SSL across multiple domains at scale. Early, plain-language warnings across the entire list mean a single missed renewal never slips through.
Features for scale
Bulk import
Add certificates in bulk by paste, CSV, Excel, ODS, or a public Google Sheet link.
One sorted list
Every certificate across every host in one sortable dashboard, ordered by soonest to expire.
Structural de-dup
Many endpoints under one registration share a single domain check — no duplicate lookups or alerts.
SSL, domains, and API
Certificate and registration expiry together, plus a REST API on the Scale and Business plans to automate at scale.
Built to monitor many certificates
Once you're past a handful of certificates, control panels and spreadsheets stop scaling. SSLCanary is built to track many SSL certificates at once — import your whole list, watch every host and CA together, and never chase renewals by hand.
