Lockdown Apps is a new firewall app for iOS. Like Guardian Firewall, which we covered last month, Lockdown uses iOS’ VPN framework to intercept all incoming and outgoing network traffic, and allows you to block connections to any address.

Unlike Guardian Firewall, Lockdown operates entirely on your device. It is also open source.
