The increasing and pervasive use of the Internet coupled with rise of Web 2.0, its subsequent interactive applications, plus complex networks have lead to more sophisticated security requirements.

Furthermore, with voice and video (multimedia) now residing on corporate networks and the resultant viruses spawning with newfound severity, the need for multiple risk mitigators, also known Unified Threat Management (UTM) has emerged.
Keeping trend with these market shifts and the evolving security solutions, security distributor, Loophold Security Distribution has introduced SonicWall's Network Security Appliance (NSA) series.
Developed to provide businesses with the tools they need to protect their corporate networks from internal and external security threats, the NSA series is now also available to mid-sized organisations.
The NSA series incorporates next-generation UTM protection, combining multiple protection technologies which include Intrusion Prevention, advanced file and content Anti-Virus / Anti-Spyware inspection that protect the network against a wide array of attacks such as viruses, spyware, worms, Trojans and phishing.
"UTM has become a de facto requirement in protecting today's modern networks. The reality is that traditional point solutions no longer provide sufficient unified protection against increasingly complex threats. UTM solutions' Deep Packet Inspection (DPI), for example, is specifically designed to audit all external and internal traffic," comments Martin Tassev, MD of Loophold Security Distribution.
In addition to UTM protection, SonicWall's NSA appliances allow for increased application visibility. With the integration of an Application Firewall, which in turn offers a suite of configurable tools, administrators can prevent content and data leaks.
The suite also allows for granular application control that can be set per user, e-mail user, per schedule and per IP subnet levels to create a future proofed solution for administrators.
For increased performance, the NSA Series uses a combination of SonicWall's patented Reassembly Free DPI (RFDPI) and purpose-built multi-core acceleration hardware.
The technology allows the SonicWall NSA appliances to eliminate threats over unlimited file sizes without affecting processing time. In addition to RFDPI, it enables unrestricted concurrent connections offering users ultimate scalability.
