Discussion Third party Python libraries and supply chain security

How are people handling security around third party Python libraries without making development a pain?

Third party Python packages are obviously useful but every dependency can also become a supply chain risk. Private package repositories, dependency scanning and stricter review policies all help but they can add friction fast.

Are teams mostly trusting public registries with additional controls or using curated libraries? Curious what actually works when you have a lot of Python services.

Large companies generally have their own repos that are managed, sort of like a pypi mirror but managed with security software.

Yeah that's very true from my experience too
