What are the advantages of a "shared policy" in R80?

Shared policies are not a user-access or identity-based mechanism; they are a policy authoring construct for reusing rule layers across packages, unrelated to identified users.

Sharing a policy among multiple administrators describes administrator collaboration and concurrent session management, which is a separate R80 feature, not the definition of a shared policy.

In R80's unified policy model, a 'shared policy' is implemented as a shared layer that can be included in multiple Policy Packages simultaneously. This means a single rule base - such as a common threat prevention or application control layer - can be authored once and attached to different packages managing different gateways, reducing administrative overhead and ensuring policy consistency.

Automatic policy propagation to multiple gateways from a single install action describes policy installation behavior, not the concept of a shared policy layer.
