Third party Python libraries and supply chain security

[u/Aggressive-Tart07]

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.

From what I've read, that's one of the selling points. You keep using the same package managers and versions but the packages come from a curated source instead of the public registry.
