About CertSteady
CertSteady is an independent, free tool that helps MSPs and IT teams get ahead of shorter TLS certificate lifetimes.
What it does
Publicly trusted TLS certificates are getting shorter lifetimes: at most 100 days from 2027 and 47 days from 2029. Certificates that are renewed by hand today will need renewing several times a year. The free Certificate Readiness Check finds the public certificates and subdomains of a domain in Certificate Transparency logs, checks what each host serves over HTTPS, flags certificates that look manually renewed, and estimates how many renewals per year the new limits mean.
What it does not do
- It never asks for, touches or stores private keys, passwords or account access.
- It reads public data only: Certificate Transparency logs and the certificate each server presents to any visitor.
- It does not change anything on your servers or renew certificates for you.
