Little Snitch is basically a firewall that allows you to control which of your programs can make outgoing network connections, and which servers they are allowed to communicate with. It would be ideal if you had a way to mark a network as untrusted and not allow any network connections until you establish a VPN connection. These cases may seem small, but ask yourself: Could any of your applications reach out via the network before youĪctivate the VPN? If your VPN disconnects for some reason, will you notice? In either case, the VPN isn’t active, so it isn’t protecting your network communication. Any time the VPN disconnects for some reason.The span between the time you join the network and the time you activate the VPN.But that still leaves two critical times: Using a VPN will secure your network traffic while you are using it.
