SonicWall Solutions for Unified Threat Management
Network attackers have become more sophisticated, and their attacks more targeted. Many of today's attacks are blended attacks, which use multiple techniques to try to infiltrate your network. You need an array of techniques to combat blended attacks. However, managing multiple, separate security tools can be overwhelming, inefficient and expensive. Unified Threat Management (UTM) is the latest approach to security-bringing a new level of efficiency to the security field.
SonicWall's own approach to UTM creates a security environment that delivers firewalling, content protection, anti-virus, anti-spam and intrusion prevention on a single hardware platform. Protection starts at the gateway, and blocks both internal and external threats, at multiple access points and at all network layers.
Reassembly-Free Deep Packet Inspection.
SonicWall® Reassembly-Free Deep Packet Inspection™ (RFDPI) (U.S. Patent 7,310,815D-A) goes beyond ordinary stateful inspection of the network layer, by also inspecting the application layer for attacks on application vulnerabilities. SonicWall RFDPI scans over 50 application types, as well as multiple protocols, including SMTP, POP3, IMAP, FTP, HTTP and NetBIOS. RFDPI matches all downloaded, e-mailed, and even compressed files against an extensive, continuously updated signature database, scanning all files in real time to block hidden threats, such as macro viruses and packed executables.
SonicWall provides this complete level of protection with no performance hit. Many other UTM solutions require file caching and rebooting to accommodate updating file signatures and scanning procedures, which slows down the computer and hinders productivity. Because SonicWall can scan files of any size without caching, and handle hundreds of thousands of concurrent downloads, it offers superior performance for any size network. In addition, SonicWall eliminates rebooting after the signature file update, so there is no need to interrupt productivity.
SonicWall UTM adds built-in gateway anti-virus, anti-spyware, comprehensive anti-spam and intrusion prevention to SonicWall® E-Class NSA, NSA and TZ Series gateway appliances. This robust level of protection offers real-time security against a wide variety of exploits, software vulnerabilities and malicious code. Offering the highest level of security available, SonicWall combines gateway protection from external attacks, with desktop protection from internal attacks from within the network. SonicWall UTM also provides Web and email security, featuring inbound and outbound email protection, as well as enforced compliance with internal polices and external regulatory mandates.
