It's very secure.
Because each user's traffic passes through a separate tunnel, no BT Wi-fi user can access another user's device. The BT Wi-fi and the private BT Business Hub SSID are completely separate so that a user cannot move from one to another.
This ensures that:-
- Visitors can't use the BT Wi-fi service to connect directly to the private hub network (or vice versa).
- All visitor and private hub network activity is clearly distinguished and allocated to the correct user.
- Private hub activity cannot be mistaken for visitor activity (or vice versa).
