Reports on Certificates - existence, expired, soon to expire, etc.
Although I'd prefer something in the Right Click Tools, this is probably more appropriate for Endpoint Insights. Collecting certificate information and reporting on expiring and expired certs would be quite valuable.
Find certificates in the environment and when expiring etc. The idea is like a wildcard cert purchased from GoDaddy that needs to be renewed every year. But certificates in general are tough to manage who/where they are installed.
