When it comes to the NSA 240 from SonicWall, perhaps the question should be “what doesn’t it do?” Built upon  the
idea that all network traffic needs to be monitored and validated, the
NSA relies on Re-Assembly Free Deep Packet Inspection (RFDPI) to
provide Intrusion Protection, Anti-Virus, Anti-Spyware, Content
Filtering, and Application Management in a single, affordable desktop


UTM appliances are nothing new to the SMB market, the NSA 240 brings
capabilities and a feature set not found in other devices. For example,
the NSA 240 includes support for 3G wireless networking cards via a PC
card slot in the device. That allows wireless broadband to be used for
connectivity – where wired connections do not exist. 3G networking can
also be used for fail over and traffic bonding. For some remote
locations, such as construction job sites or undeveloped areas, the
inclusion of 3G support is a must-have, bringing Internet connectivity
to areas where none existed before.


course, other solutions exist that allow 3G wireless networks to be
created, but none offer the integrated UTM capability, along with VPN
support and all of the security features found in the NSA 240.


The product offers a very robust feature set and includes:

        Deep Packet Inspection Firewall.

        Gateway anti-virus, anti-spyware, intrusion prevention, and application firewall for perimeter and internal protection.

        Application Firewall, business application prioritization and QoS.
