The encrypted tunnels that VPNs use pose yet another security problem. Sure, the outside world can’t see them, but you are also blind to the traffic going through the fully SSL-encrypted tunnels as well. That means you don’t have the opportunity to thoroughly inspect the traffic coming in through the VPNs before it’s placed on your network.
While there is the ability now to do some packet filtering with VPNs, the tradeoff in processing power makes their use very inefficient. Not only does the performance of the VPN slow down dramatically, but so does your infrastructure across the board. In a situation where you need to ramp up the processing power of a VPN, a way to do that is to turn off its security features. But then you’re flying blind.
TAC was designed from the ground up to guarantee optimum performance with its complete portfolio of security features running. TAC unencrypts traffic, inspects it and makes sure it’s valid for the application that it’s going to, then re-encrypts the traffic and sends it to the application. Oh, and this in-depth assessment of the traffic coming in from remote locations? TAC completes it seamlessly, before the user even touches the network – without any lulls in performance.
