The SonicWALL Network Security Appliance Series nsa_2400_3500_4500_5000 
Organizations of all sizes depend on their networks to access internal and external mission-
critical applications. As advances in networking continue to provide tremendous benefi t to
organizations, they are increasingly challenged by sophisticated and fi nancially-motivated
attacks designed to disrupt communication, degrade performance and compromise data.
Malicious attacks penetrate outdated stateful packet inspection fi rewalls by exploiting higher
network levels. Point products add layers of security, but are costly, diffi cult to manage, limited
in controlling network misuse and ineff ective against the latest multipronged attacks. The
SonicWALL® Network Security Appliance (NSA) Series revolutionizes network security, utilizing
a breakthrough multi-core design and patented Reassembly-Free Deep Packet Inspection™
(RFDPI) technology* off ering complete protection without compromising network performance.
This platform was fi rst made available on the SonicWALL E-Class NSA Series, and it is now
available for mid-sized organizations.
The NSA Series overcomes the limitations of existing security solutions by scanning the entirety
of each packet for current internal and external threats in real time. Built on a high-speed multi-
core processing platform, the NSA Series enables deep packet inspection without adversely
impacting the performance of mission-critical networks and applications.
The NSA Series applies next-generation Unifi ed Threat Management (UTM) against a
comprehensive array of attacks, combining intrusion prevention, anti-virus and anti-
spyware with the application-level control of SonicWALL Application Firewall. With
advanced routing, stateful high-availability and high-speed VPN technology, the NSA Series
adds security, reliability, functionality and productivity to branch offi ces, central sites and
distributed mid-enterprise networks, while minimizing cost and complexity.
Comprised of the SonicWALL NSA 2400, NSA 3500, NSA 4500 and NSA 5000, the NSA Series
off ers a scalable range of solutions designed to meet the network security needs of any organization.
