Introduction

SonicWALL NSA 220 is a powerful and a perfect security solution for distributed enterprises and branch offices. The appliance can be upgraded to a wireless device by paying just a few extra dollars, which then supports IEEE 802.11a/b/g/n wireless networks. SonicWALL NSA 220 also allows security administrators to filter unwanted applications and block them from being used. Moreover, the appliance can be configured to block inappropriate websites and/or potentially harmful scripts from entering the network.

Who Should Buy?

SonicWALL NSA 220 is best suited for:

• Branch Offices – The appliance can be installed and configured in the branch offices that frequently communicate with external network and require a secure VPN tunnel to the main office for remote accessing.
• Distributed Enterprise – An enterprise that has multiple branch offices connected together can also use SonicWALL NSA 220 security appliance to establish an SSL VPN tunnel for secured communication.

What Purposes It Serves?

SonicWALL NSA 220 can be counted as one of the efficient appliances to provide security to VPN connections, internal network and sensitive data by preventing the network from virus attacks, spywares, malwares, etc. With the help of SSL VPN, the appliance can provide security administrators a secured VPN tunnel for remote accessing.

When optional wireless model is opted, SonicWALL NSA 220 allows dual band wireless networks that work on both 5 GHz and 2.4 GHz frequencies. Organizations that require maximum network connectivity can also use this network security appliance to configure stateful hardware failover.

Top Features and Benefits

Some of the important features and benefits of SonicWALL NSA 220 are:

• Deep Packet Inspection – SonicWALL NSA 220 appliance enables Deep Packet Inspection in order to allow or restrict unwanted applications or protocols from entering into the network or accessed remotely.
• Deep Packet Inspection SSL – The appliance also allows security administrators to configure DPI-SSL. This means that the appliance is capable of decrypting, inspecting and re-encrypting any SSL encrypted packet before the packet is allowed to enter into the network.
• Secured Virtual Private Networking – Security administrators can create both IPSec and SSL VPN tunnels using SonicWALL NSA 220 security appliance. This enables secured remote access to branch offices and remote sites by encrypting the data packets.
• Intrusion Prevention – SonicWALL NSA 220 is capable of preventing the network from intrusions. Scanning of unwanted packets is done on network and application layer, hence doubling up the protection of the network from any unauthorized access.
• WAN Acceleration – When SonicWALL NSA 220 is integrated with SonicWALL’s WAN Acceleration Appliance (WXA), security administrators can configure the appliance to throttle down or completely block any unwanted application and website in order to increase organization’s productivity.
• Gateway Protection – When administrators configure SonicWALL NSA 220 as a network gateway, the appliance can protect the internal network from spyware, malware, virus attacks, potentially harmful scripts, etc. All unwanted and malicious packets are blocked at the gateway itself.
• Mobile Connectivity – With the help of Apple iOS and Android based client app named ‘Mobile Connect’, users can establish SSL VPN connections to the internal network from remote locations. Mobile Connect allows remote users to gain network level access to the internal network and also allows them to access the resources that are available in the network.
• Application Control – SonicWALL NSA 220 allows security administrators to granularly control the network traffic of potentially harmful and unwanted applications. Applications’ traffic can be controlled even on the distributed locations, provided the same appliance is deployed.
• Wireless Connectivity – SonicWALL NSA 220 supports both 5 GHz and 2.4 GHz wireless networks. This means that the wireless model of the appliance is capable of handling IEEE 802.11a/b/g/n wireless networks. Since the appliance supports IEEE 802.11 n wireless network as well, a decent network speed can be experienced on unguided media. SonicWALL NSA 220 can also be used to extend wireless networks by using SonicPoints. This allows security administrators to deploy a secured wireless network infrastructure for an enterprise.
• Stateful Hardware Failover – SonicWALL NSA 220 supports stateful hardware failover in order to provide uninterrupted network connectivity throughout the enterprise. Because of the concept of virtual MAC, even the SSL VPN remote sessions remain uninterrupted in case the active appliance fails.
• Centrally Managed Policies – With the help of Global Management System (GMS), SonicWALL NSA 220 allows security administrators to configure and manage security policies quite efficiently and from a central location. This saves administrators’ decent amount of time which they can utilize by focusing on other aspects of the network.
