The SonicWALL Network Security Appliance (NSA) 220 and NSA 220 Wireless-N Series high-performance Next-Generation Firewalls offer branch offices and distributed enterprises in-depth frontline security, application and user control, network productivity and optional 802.11 dual-band wireless. The NSA 220 Series firewalls act as the first line of network defense against viruses, Trojans, key-loggers and other application layer attacks, without compromising network performance. Management is simplified by consolidating many functions, including network security, remote access and wireless.
The NSA 220 Series provides anti-malware, intrusion prevention and web content filtering at branch offices without compromising performance at those locations. IT administrators can granularly view and control bandwidth-consuming and potentially dangerous application traffic over the network, even between widely distributed locations. Network productivity can increase because IT administrators can identify and throttle or block unauthorized, unproductive and non-work-related appliances and websites such as Facebook or YouTube and optimize WAN traffic when integrated with SonicWALL WAN Acceleration Appliance (WXA) solutions.
Gateway anti-virus and anti-spyware provide high-performance protection against millions of unique pieces of malware with near zero latency and no file size limitations. This provides a first layer of defense and stops malware before it can reach systems on your network. Tightly integrated, signature-based network intrusion prevention protects against a comprehensive array of network and application layer threats by scanning packet payloads for attacks and exploits targeting critical internal systems.
High-performance Virtual Private Networks (VPNs) easily scale to thousands of endpoints and branch offices. And SonicWALL Clean VPN technology protects the integrity of both your IPSec and SSL VPN traffic, securing your remote access tunnels and decontaminating the traffic running across it. SonicWALL’s patented Reassembly-Free Deep Packet Inspection engine1 combined with SonicWALL’s NSA 220 dual-core security platform is capable of inspecting hundreds of thousands of connections simultaneously across all ports. With nearly zero latency and without file size limitations, the system provides 110 Mbps of Deep Packet Inspection across 7 GbE copper interfaces.
