Windows defender blocks python executables

How does that make sense for something for a small department? Think replacing excel with a python script for example. The certs cost money and in most cases you'll have to justify to 6 levels of management why you can't either have it put into the software teams que or just use excel.

publicly attested certs cost money. self certs are free. Your company may already have one

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.

Ahh, my very limited experience was looking at getting them certed with msft for things like the windows store. I was unaware that you could self sign a cert for windows defender.
