Organisations of all sizes depend on their networks to access internal and external mission-critical applications. Yet increasingly sophisticated and financially-motivated network attacks compromise data, disrupt communications and degrade performance.  Malicious attacks penetrate outdated stateful packet inspection firewalls by exploiting higher network levels. Point products add layers of security, but are costly, difficult to manage, limited in controlling network misuse and ineffective against the latest multipronged attacks. The SonicWALL NSA Series revolutionizes network protection, utilizing a breakthrough multi-core design and multi-tiered threat protection without compromising network performance.

The SonicWALL Network Security Appliance (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. Built on a high-speed multi-core processing platform, the NSA Series enables deep packet inspection without adversely impacting the performance of mission-critical networks and applications.

The NSA Series applies next-generation Unified Threat Management (UTM) against a comprehensive array of attacks, combining intrusion prevention, anti-virus and anti-spyware with the application-level control of SonicWALL Application Firewall. With advanced routing, stateful high-availability and high-speed 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.

Dynamic Security Architecture and Management

Best-in-Class Threat Protection

• SonicWALL deep packet inspection protects against network risks such as viruses, worms, Trojans, spyware, phishing attacks, emerging threats and Internet misuse. Application Firewall adds highly-configurable controls to prevent data leakage and manage bandwidth at the application level.
• The SonicWALL Reassembly-Free Deep Packet Inspection (RFDPI) technology utilises SonicWALL's multi-core architecture to scan packets in real-time without stalling traffic in memory. This functionality allows threats to be identified and eliminated over unlimited file sizes and unrestricted concurrent connections, without interruption.
• The Network Security Appliance Series provides dynamic network protection through continuous, automated security updates, protecting against emerging and evolving threats, without requiring any administrator intervention.

Unified Threat Management Load Balancing

• Single processor designs that include multiple protection technologies are severely limited by a single centralised processor. SonicWALL UTM load balancing integrates a high-speed deep packet inspection and traffic classification engine onto multiple security cores inspecting applications, files and content-based traffic in real time without significantly impacting performance or scalability. This enables the scanning and control of threats for networks that carry bandwidth intensive and latency sensitive applications.

SonicWALL Clean VPN

• The Network Security Appliance Series includes innovative SonicWALL Clean VPN technology which decontaminates vulnerabilities and malicious code from remote mobile users and branch offices traffic before it enters the corporate network, and without user intervention.

Centralised Policy Management

• The NSA Series can be managed using the SonicWALL Global Management System (GMS) or the NTS HANDS hosted service which provide flexible, powerful and intuitive tools to centrally manage configurations, view real-time monitoring metrics and integrate policy and compliance reporting.
