With upstream proxying we'll cache upstream packages for you, for convenient access from Cloudsmith. You can reduce the amount of external repositories you depend on, and you can protect your software and servers from downtime and slowness of official main repositories.
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.
