Private/internal repositories limit package access to authorised clients and users, without sharing packages to the world. If you need internal software distribution mechanics, or if you want to support license-based software distribution, then private repositories facilitates these.
Granular Access Controls
Add granular access controls to your repositories and packages to give appropriate access to collaborators or teams within your organization. Need read-only access for junior developers or one single repository for contractors?
Restrict or grant access to your packages based on geographical location, IP ranges or specific IP addresses. If you need to add physical location security to your package management, then Geo/IP Restriction is what you need.
