Product features.

The NSA 220 Series offers an extensive array of advanced networking and configuration flexibility features in an accessible, affordable platform that is easy to deploy and manage in a wide variety of environments.

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.

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.

Mobile Connect.

Mobile Connect™, available as a mobile app for Apple® iOS , Mac OSX, Kindle Fire and Google® Android™ mobile devices and embedded with Windows 8.1 devices, provides users with simple, policy-enforced access to corporate and academic resources over encrypted SSL VPN connections.

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.

Dell SonicWALL’s patented Reassembly-Free Deep Packet Inspection® engine1 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.

Platform features.

SonicOS provides key features designed to ensure the security of your network with an intuitive graphical user interface for increased functionality and ease of use.

Deep Packet Inspection firewall.

Dell SonicWALL Reassembly-Free 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.

Deep Packet Inspection for SSL Encrypted Traffic (DPI-SSL).

DPI-SSL transparently decrypts, inspects and re-encrypts SSL encrypted traffic to allow security services to be applied to all traffic that traverses Dell SonicWALL Next-Generation Firewalls.

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.

Clean Wireless.

Dell SonicWALL firewalls can be extended with secure wireless access points, SonicPoints, to provide seamless and secure 802.11 a/b/g/n wireless networks protected with the Dell SonicWALL Clean Wireless technology.

Powerful reporting.

Historical reporting on user activity is available through Dell SonicWALL Analyzer software and real-time application analysis through powerful visualization tools.

Secure Network Optimization.

Stay ahead of today’s constantly evolving landscape of threats and application-related issues with an advanced security platform that consolidates Dell SonicWALL Next-Generation Firewall features for enterprises along with WAN acceleration for distributed offices to maximize security and control with minimum network latency.

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.

Centralized Policy Management

The Dell SonicWALL Global Management System (GMS®) provides flexible, powerful and intuitive tools to manage configurations, view real-time monitoring metrics and integrate policy and compliance reporting, all from a central location.
