Cloudflare has open-sourced a new APT transport that allows customers to protect their private APT repositories using Cloudflare Access. The company's internal DevTools team built and tested the custom APT transport, which generates necessary tokens and passes correct headers in HTTPS requests to an internal APT repository server. By protecting your APT repository with Cloudflare Access, users can support authenticating via Single-Sign On (SSO) providers, defining comprehensive access-control policies, and monitoring access and change logs.
