+# Approve peers
+The peer approval feature enhances network security by requiring manual administrator approval before a device can join the NetBird network.
+This feature is handy when network administrators want to ensure access is restricted only to trusted, corporate-managed devices.
+
+When enabled, devices connect to the management service without network access to other resources.
+Administrators then can assess whether the peer is eligible to join the network.
+
+<Note>
+    This feature is only available in the [NetBird cloud](https://app.netbird.io/) version.
