Today's small business networks are susceptible to the same types of attacks as those faced by larger networks. And, while hackers have gained the most notoriety, it's actually viruses, spyware and worms that pose the most significant security threat. Low-end security appliances simply don't provide adequate protection from these threats and high-end solutions blow the budget. What's needed is an integrated solution that provides the security of a deep packet inspection firewall at a price small businesses can afford. The TZ 150 Wireless, a key component of SonicWALL's TZ 150 Series, is a complete layered security platform integrating secure 802.11b/g wireless and a deep packet inspection firewall in an easy-to-use, low cost platform. Its compact form factor includes a single auto-MDIX Ethernet WAN port and four-port auto-MDIX LAN switch, allowing multiple devices to connect safely to the network. Advanced features such as enforced VPN encryption on the wireless LAN and wireless intrusion detection and prevention services deliver impenetrable wireless security. Utilizing the Wireless Guest Services feature, network administrators can create multiple zones of access - for wired and wireless workers as well as guest wireless users - offering an unprecedented level of control without compromising network security.
