Monitor multiple certs on one server?



Is there a way to do this without adding a URL/IP that points to the site? I need the sensor to just check a specific cert on this server without using an http: URL.

I have a device pointing to the specific server. Trying to create SSL sensors now for each specific cert.

When I add a cert sensor to the server, using port 443, I receive a "failed to establish secure connection" error.

Thanks for any help.

Hello there,

It might work with running WinCertExpiration from here as a custom sensor.

Kind regards,
