Gone are the days when a dedicated firewall is sufficient to fend off hackers from cooperate networks. Unified Threat Management (UTM) is an emerging trend in the network security appliance market. Always on the cutting edge, ZyXEL's ZyWALL 35 UTM is capable of outperforming the current ZyWALL 35 by up to 20 times with just a ZyWALL Turbo Card. This new technology introduces a new all in one network security device that provides content filtering, anti-virus, anti-spam and intrusion detection services traditionally handled by multiple systems.
