A dedicated SSL certificate monitor
CertFleet watches your certificates continuously — reading the live cert served on :443 and tracking Certificate Transparency — and pages you before anything expires.
Most outages from certificates are entirely preventable. CertFleet checks every monitored hostname on a schedule and compares against the last known certificate.
Because we probe the live certificate, we catch the case CT-only tools miss: a renewed cert that was never deployed.
Staged alerts at 30 / 14 / 7 / 1 days reach you on email, Slack and signed webhooks — idempotently, so you are never double-paged.
