Is Atlan safe?

Low risk

Atlan exposes its install/configuration status and saved language to any website through its external message API.

Any website can send Atlan external messages that return whether the extension is installed, configured, or managed by an organization, along with the saved language value. The same unauthenticated external message API can also close the sender's tab after setup.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
