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.

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.

Deep Packet Inspection firewall

SonicWALL Deep Packet Inspection technology scans against multiple application types and protocols to protect against internal and external threats at both the application layer and the network layer.

SSL VPN remote access

Integrated SSL VPN technology enables clientless, remote access to email, files, intranets, and applications from a variety of platforms. An SSLVPN client can also be automatically pushed out to the client and auto-configured to provide secure layer 3 connectivity.

Business continuity

Your network will continue to operate without interruption even if there is a hardware or software failure with active/passive failover. Stateful synchronization across the appliances enables failover without interruption to existing network traffic and VPN tunnels.
