I've actually been building a tool that does just this during the current YC Startup School program.

You can get on the launch list here: https://watchdog443.com

My main focus is ongoing alerting of changes to HTTPS configs rather than just a one off check. So you can be confident that everything is up to your spec or know as soon as something isn't.

Because we'll know your setup we can also alert you to things you specifically should be aware of - for instance a browser policy change that would affect user experience due to your certificates not meeting the browser policy etc.

Feel free to mail me if you'd like more info! (email in profile.)

(PS. YC Startup School's virtual demo day is tomorrow if you're interested! All the startups that completed the course are posting a short demo video.)
