To close this gap we’ve introduced the Internet Access Policy (IAP) in Little Snitch 4. This allows third party app developers to bundle a policy file with their app that contains information about the Internet connections the app establishes and what purpose they serve. Little Snitch uses this information to help you decide whether to allow or deny a connection.

The list of applications that support it is impressive, including 1Password, BBEdit, Bear, iStat Menus, SuperDuper!, and Ulysses.
