A Firewall is a first line of defense in protecting proprietary information within the access-point managed network. Firewall helps blocking and permitting data traffic in the network.

With WiNG access points, firewalls are configured to protect against unauthenticated logins from outside the network. This helps prevent hackers from accessing managed wireless clients. Well designed firewalls block traffic from outside the network while permitting authorized users to communicate freely outside the network.

All traffic entering or leaving a controller or service platform passes through the firewall, which examines each message and blocks the ones that do not meet the predefined security rules.
