Free SSL/TLS Certificate Discovery Scan
Find out which publicly trusted TLS certificates are issued for your domain, which ones expire soon and which ones need attention, so you are ready for shorter certificate lifetimes.
Free scan
What your free scan covers
Tell us the domain to check. We look at the publicly trusted TLS certificates issued for it and show you what needs attention.
Public certificates
Find the publicly trusted TLS certificates on your domain.
Expiry dates
See certificates close to expiry before they cause outages.
Weak or unexpected certificates
Spot weak, misconfigured or unexpected certificates.
Issuers and policies
Check issuers and policies against your standards.
Why now
Certificate lifetimes are getting shorter
Public TLS certificate lifetimes are shrinking in steps toward 47 days. Shorter lifetimes mean more renewals, and every certificate you do not know about is a possible outage. Read more: 47-day TLS certificates: what the timeline means.
