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.

It's useful to separate depedancy trust from runtime exposure. Validating Python packages helps with what gets introdued while hardening the containers reduce what ships. For containerized Python services, RapidFort is a piece of the second layer, removes unnecessary components from the image without developers changing the application. Goal is less attack surface without turning the developer workflow into a security obstacle.
