Organizations of all sizes depend on their networks to access internal and external mission-critical applications. As advances in networking continue to provide tremendous benefits, organizations are increasingly challenged by sophisticated and financially-motivated attacks designed to disrupt communication, degrade performance and compromise data. Malicious attacks penetrate outdated stateful packet inspection firewalls with advanced application layer exploits. Point products add layers of security, but are costly, difficult to manage, limited in controlling network misuse and ineffective against the latest multipronged attacks.

By utilizing a unique multi-core design and patented Reassembly-Free Deep Packet Inspection® (RFDPI) technology, the SonicWall™ Network Security Appliance (NSA) Series of Next-Generation Firewalls offers complete protection without compromising network performance. The low latency NSA Series overcomes the limitations of existing security solutions by scanning the entirety of each packet for current internal and external threats in real-time. The NSA Series offers intrusion prevention, malware protection, and application intelligence, control and visualization, while delivering breakthrough performance. With advanced routing, stateful high-availability and high-speed IPSec and SSL VPN technology, the NSA Series adds security, reliability, functionality and productivity to branch offices, central sites and distributed mid-enterprise networks, while minimizing cost and complexity.

Comprised of the SonicWall NSA 220, NSA 220 Wireless-N, NSA 250M, NSA 250M Wireless-N, NSA 2400, NSA 3500 and NSA 4500, the NSA Series offers a scalable range of solutions designed to meet the network security needs of any organization.

Features and benefits

Next-Generation Firewall features integrate intrusion prevention, gateway anti-virus, anti-spyware and URL filtering with application intelligence and control, and SSL decryption to block threats from entering the network and provide granular application control without compromising performance. Scalable multi-core hardware and Reassembly-Free Deep Packet Inspection scans and eliminates threats of unlimited file sizes, with near-zero latency across thousands of connections at wire speed.

Application intelligence, control and visualization provides granular control and real-time visualization of applications to guarantee bandwidth prioritization and ensure maximum network security and productivity.

Stateful high availability and load balancing features maximize total network bandwidth and maintain seamless network uptime, delivering uninterrupted access to mission-critical resources, and ensuring that VPN tunnels and other network traffic will not be interrupted in the event of a failover.

High performance and lowered tco are achieved by using the processing power of multiple cores in unison to dramatically increase throughput and provide simultaneous inspection capabilities, while lowering power consumption.
