Going far beyond simple stateful inspection, SonicWALL’s E-Class Network Security Appliance (NSA) deep packet inspection engine (DPI) scans against multiple application types and protocols, ensuring your enterprise-class network is protected from both internal and external attacks as well as application vulnerabilities. The NSA Series combines enterprise-level threat protection and scalability with an ultra-high-speed parallel performance architecture that employs up to 16 processor cores. Unlike other scanning engines, SonicWALL’s DPI engine is not limited by file size or the amount of concurrent traffic it can scan, making these solutions second to none. By working at the application layer, DPI also protects against hidden application vulnerabilities that may be inadvertently letting attackers in through an unknown back door.
Reassembly-Free Deep Packet Inspection (RFDPI)
At the heart of every SonicWALL network security solution is our patented RFDPI engine. SonicWALL’s pioneering RFDPI technology unifies multiple security products into a single integrated suite, enabling administrators to manage local, remote and mobile network security simply and cost-effectively. RFDPI increases productivity by allowing IT to create reusable and adaptive policy control. More than simply a security approach, RFDPI incorporates object-based contextual controls over user identity and access; application identity and access; data leakage; network optimization; as well as granular reporting, auditing and forensics.
PROTECTION AGAINST APPLICATION VULNERABILITIES
The development cycle of most commercial software is fast. No matter how skilled the developers are, hidden vulnerabilities can appear, even in the most robust of software packages. While developers work quickly to find and close these vulnerabilities, hackers work just as quickly to find and exploit them. Deep packet inspection examines all downloaded, e-mailed, and compressed files, and examines information at the application layer to protect against the more sophisticated (and more prevalent) attacks that target application vulnerabilities.
PROTECTION AGAINST BOTH INTERNAL AND EXTERNAL ATTACKS
The attacks that happen daily against enterprise networks don't just come from hackers halfway across the world. Many come from within the enterprise organization. Disgruntled employees or trusted workers who have inappropriate access can be considered a threat. In addition, internal threats may appear completely by accident. Honest employees may accidentally open up a back door without even realizing it.
Deep packet inspection scans multiple application types and covers many protocols, including SMTP, POP3, IMAP, FTP, HTTP, NetBIOS and many other protocols and application types. It also scans all network layers. As a result, the enterprise network is protected from both internal and external threats.
