What this tool does not do — and therefore does not sell: Certprobe has no user accounts, no saved history, no email alerts, no scheduled re-checks. There is no email sender in this fleet, no database, and no cross-device state. Every probe is a standalone interaction; the result is shown on screen and gone on refresh. If scheduled monitoring or email alerts are important to you, Certprobe is not the right tool today.
