The NetLOCK products are just being introduced. Thus, their VPN technology has not been exposed to the real network attacks. Their security implementation is also jeopardized with exchanging weak UDP datagrams. On the contrary, AltaVista is a proven, very reliable technology which has been available for
more than a year. Unlike NetLOCK, AltaVista supports not only business to business VPNs but also personal tunnels. AltaVista pricing strategy is extremely more competitive than that of NetLOCK.
