Read the full description
CertHalo watches your SSL/TLS certificates from the outside and alerts you before one expires, or the moment one is renewed, revoked, changes issuer, stops matching its hostname or goes unreachable. Each check grades the full certificate health A to F. Alerts by email, Slack or Microsoft Teams, with shared team workspaces. Nothing to install, works with any host or CA. Free for 3 certificates; paid plans from $3/month.
