Aside from receiving plenty of emails well in advanced from my PKI telling me one of my certificates is about to expire, how can I setup an alert that checks the health of an SSL?
What I want to check for:
- Hasn't expired
- Hasn't been revoked
- Hasn't been removed from the server accidentally
Currently we use Hostmon internally and SiteUptime externally. The latter can use HTTPS, but it doesn't appear to have the ability to validate certificates.
