Product Description

Dell SonicWALL NSA 220 Wireless-N Security Appliance

  • Distributed network security
    The NSA 220 series provides anti-malware, intrusion prevention and web content filtering at branch offices without compromising performance at those locations.
  • Application control and visualization
    IT administrators can granularly view and control bandwidth-consuming and potentially dangerous application traffic over the network, even between widely distributed locations.
  • WAN acceleration
    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 Dell SonicWALL WAN Acceleration Appliance (WXA) solutions.
  • Gateway anti-malware
    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.
  • Intrusion prevention
    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.
  • Virtual private networking
    High-performance Virtual Private Networks (VPNs) easily scale to thousands of endpoints and branch offices. And Dell 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.
  • High performance
    SonicWALL's patented Reassembly-Free Deep Packet Inspection engine combined with Dell 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.
