We basically use this solution to filter traffic so that the network can be secured and no one can hack the network. We are using WatchGuard as a gateway security product. It is installed on the gateway to filter the traffic for our network, stop access to malicious websites, and protect our interwork network from any kind of hack attempt from outside.
We are also using the VPN feature. The traffic is encrypted via a VPN, and no one can hack it. We are using the latest version of this solution.
