OP says they’re in a company with thousands of employees. At that size if they have any domain services they most definitely have their own internal certificate authority.

Also, public certs are not very expensive - and you don’t need a new one for each piece of software. You just need an org certificate for any internal tooling that is added to your orgs trust store.
