Automated retention/lifetime rules allows you to automatically manage storage for packages by deleting or moving packages that fall outside of the defined retention rules.
Access your packages via a white-labelled domain specified by you. If your company brand and trust is important to you and your customers, whitelabelling will allow you to present your own company's domain as the endpoint for storage and configuration such as GPG keys, install scripts, etc.
Entitlements allow you to control who has read-only access to your package repositories. Whether you're automating server or application installs, or you're building a license-only software distribution, entitlements facilitates these.
