Deep Packet Inspection Firewall
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.
