Dell SonicWALL NSA Series appliances provide enterprise networks with continuous real-time threat protection, ensuring the strongest defense posture with minimal IT intervention. Dell SonicWALL's dynamic security services continuously communicate with worldwide network of back-end centers, immediately updating signatures to protect against malicious code, vulnerabilities, and unproductive Web sites. NSA appliances integrate market-leading customizable Application Firewall for regulating application access, data leakage prevention, and user access control, giving enterprise administrators complete control over every communication to every destination across the network.
Every day, malware, spyware and real-time applications become more sophisticated, and now have the ability to circle the entire globe in a matter of minutes. Many threats are blended, originating from multiple sources over many different protocols, operating at multiple layers, over multiple protocols, delivered via IM, P2P, file sharing, games or harmless-looking utility programs and bypassing traditional client-based solutions. Today's complex threats require a solution beyond standard anti-virus technology.
SonicWALL Gateway Anti-Virus and Anti-Spyware features a deep packet inspection (DPI) engine that inspects all e-mail, Web, file transfer, and other stream-based protocols, as well as real-time applications such as IM and P2P for total application and threat control. Unlike other solutions, Dell SonicWALL DPI analyzes all files in real time - regardless of file size or compression - and generates proactive alerts that notify administrators whenever a threat is detected. Dell SonicWALL prevents day-zero attacks with dynamically-updated databases and an extensive list of virus and malware signatures. Dell SonicWALL blocks spyware at the gateway with anti-spyware technology that prevents users from downloading spyware in the first place. In addition, it prevents auto-installation of ActiveX components (one of the most common sources of spyware) and stops any existing spyware programs from communicating with their hosts.
Many of the most dangerous threats function at the application layer, exploiting vulnerabilities in common network applications to drain productivity and steal data. Application layer threats defy old guard technology - but Dell SonicWALL goes a step beyond by scanning for worms, Trojans, software vulnerabilities, backdoor exploits, and other types of malicious attacks.
Working in conjunction with Dell SonicWALL anti-virus and anti-spyware technology, the Dell SonicWALL Intrusion Prevention Service (IPS) engine protects against an array of network-based application vulnerabilities and exploits. Deployed to protect against both internal and external threats, Dell SonicWALL IPS monitors the network for malicious or anomalous traffic, then blocks or logs traffic based on predefined and automatically updated conditions. By focusing on known malicious traffic, Dell SonicWALL IPS decreases false positives while increasing network reliability and performance.
SonicWALL Application Firewall is a set of granular, application specific policies that allow custom access controls based upon user, application, schedule or IP subnet level. Its comprehensive policy capabilities include restricting transfer of specific files and documents, blocking e-mail attachments using a user-configurable criteria, customized application control, bandwidth limiting for matched policies, and denying internal and external Web access based on various user-configurable options. Using Application Firewall, Dell SonicWALL NSA solutions provide application level access control, data leakage control functionality, and the ability to create pure custom signatures - adding up to a future-proofed solution for enterprise network administrators.
