Unaffiliated. I stumbled upon this because I searched far and wide for something similar that was open source or on github, and while there is a lot out there, there's really nothing like what this does. So finally I searched GH by newly updated and found this, extremely new project. It's really excellent IMO for discovery, inventory, visibility, etc. I tried out for instance Gatus, and it really shows nothing about the cert or target host. Love how much info this shows.
