The Network Security SonicOS Platform Unified Threat Management

As a multi-service platform, Dell SonicWALL’s line of network security appliances incorporates the broadest level of protection available through Unified Threat Management (UTM). UTM combines multiple security features into a single platform to protect against attacks, viruses, Trojans, spyware and other malicious threats. Complexity is reduced and management is simplified because multiple layers of protection are delivered under this single management console.

Increase security by reducing complexity.

Companies that deploy multiple separate devices and software, each with its own interface, management console and login, find that these solutions quickly become unmanageable. Cobbled-together security platforms are inherently prone to error because there are so many things to manage. And an improperly managed security platform can be worse than none at all. Dell SonicWALL firewall appliances increase security by reducing complexity. In addition to enhanced security, our integrated platform of security products built around our leading firewall appliances delivers a cost advantage that can save you money over security systems assembled from separate products.

Gateway anti-virus, anti-spyware and intrusion protection.

The E-Class Network Security Appliance Series, NSA Series and TZ Series extends security from the network core to the perimeter by integrating support for Dell SonicWALL's Gateway Anti-Virus, Anti-Spyware and Intrusion Protection Service and Application Intelligence, delivering real-time protection against the latest blended threats—including viruses, spyware, worms, Trojans, software vulnerabilities and other malicious code. This powerful combination protects against application-layer and content-based attacks. A heightened level of gateway protection addresses multiple threat access points and thoroughly scans all network layers.

Reassembly-Free Deep Packet Inspection.

Our Reassembly-Free Deep Packet Inspection™ engine delivers threat protection directly on the security gateway by scanning against multiple application types and protocols and matching files against an extensive signature database. This unique deep packet inspection approach protects against both internal and external threats against both the application layer and the network layer.

No performance hit.

Several security companies have adopted this approach to provide the necessary security platforms their customers require. Many of these solutions, however, require file caching and rebooting during the file scan and update processes, and this causes a serious performance problem.

Dell SonicWALL network security appliances do not require file caching or rebooting, and can handle unlimited file sizes and hundreds of thousands of concurrent downloads. With its superior scalability and performance edge, Dell SonicWALL is capable of providing full network protection without compromising network throughput.

Without the reboot requirement after signature updates, Dell SonicWALL is able to offer continuous protection—so your productivity is not affected.
