Sonicwall NSA Series


SonicWALL Network Security Appliance (NSA) Series

The Dell SonicWALL Network Security Appliance (NSA) series provides mid-sized networks, branch offices and distributed enterprises with advanced threat prevention in a high-performance security platform. Combining next-generation firewall technology with our patented* Reassembly-Free Deep Packet Inspection (RFDPI) engine on a multi-core architecture, the NSA series offers the security, performance and control organizations require.


Superior threat prevention and performance

NSA series next-generation firewalls (NGFWs) integrate a series of advanced security technologies to deliver a superior level of threat prevention. Our patented single-pass RFDPI

threat prevention engine examines every byte of every packet, inspecting both inbound and outbound traffic simultaneously. The NSA series leverages on-box capabilities including

intrusion prevention, anti-malware and web/URL filtering in addition to cloudbased services such as CloudAV and Dell SonicWALL Capture multi-engine sandboxing to block zero-day threats at the gateway. Unlike other security products that cannot inspect large files

for hidden threats, NSA firewalls scan files of any size across all ports and protocols. The security architecture in Dell SonicWALL NGFWs has been validated as one of the industry’s best

for security effectiveness by NSS Labs which awarded Dell SonicWALL its “Recommended” rating for the fourth consecutive year. Going beyond intrusion prevention, anti-malware and web filtering, Dell SonicWALL NGFWs provide a further level of protection by decrypting and inspecting SSL/TLS encrypted web traffic for hidden threats in real time. With the continued growth of encrypted web traffic, organizations are effectively blind to an estimated

one-third of their network traffic. This makes SSL/TLS decryption and inspection a critical component of any security solution. When organizations activate deep

packet inspection functions such as intrusion prevention, anti-virus, antispyware, SSL decryption/inspection and others on their firewalls network performance often slows down, sometimes dramatically. NSA series firewalls feature a multi-core hardware architecture that utilizes specialized security microprocessors. Combined with our RFDPI engine, this unique

design eliminates the performance degradation networks experience with

other firewalls. In today’s security environment it’s not enough to rely on solely on outside

parties for threat information. That’s why Dell SonicWALL formed its own in-house threat research team more than 15 years ago. This dedicated team gathers, analyzes and vets data

from over one million sensors in its Global Response Intelligent Defense (GRID) network. Dell SonicWALL also participates in industry collaboration efforts and engages with threat research communities to gather and share samples of attacks and vulnerabilities. This shared threat intelligence is used to develop real-time countermeasures that are automatically deployed to our customers’ firewalls.

Network control and flexibility



At the core of the NSA series is SonicOS, Dell SonicWALL’s feature-rich operating

system. SonicOS provides organizations with the network control and flexibility they require through application intelligence and control, real-time visualization, an intrusion prevention system (IPS) featuring sophisticated anti-evasion technology, high-speed virtual private networking (VPN) and other robust security features. Using application intelligence and

control, network administrators can identify and categorize productive applications from those that are unproductive or potentially dangerous, and control that traffic through

powerful application-level policies on both a per-user and a per-group basis (along with schedules and exception lists). Business-critical applications can be prioritized and allocated

more bandwidth while non-essential applications are bandwidth-limited. Real-time monitoring and visualization provides a graphical representation of applications, users and bandwidth

usage for granular insight into traffic across the network. For organizations that require advanced flexibility in their network design, SonicOS offers the tools to securely segment the network through the use of virtual LANs (VLANs) which enable network administrators to

create a virtual LAN interface that allows for network separation into one or more logical groups. Administrators create rules that determine the level of communication with devices on

other VLANs. Built into every NSA series firewall is a wireless access controller that enables

organizations to extend the network perimeter securely through the use of wireless technology. Together, Dell SonicWALL firewalls and SonicPoint 802.11ac wireless access points create

a wireless network security solution that combines industry-leading nextgeneration firewall technology with high-speed wireless for enterprise-class network security and performance

across the wireless network.



Easy deployment, setup and ongoing management

Like all Dell SonicWALL firewalls, the NSA series tightly integrates key security, connectivity and flexibility technologies into a single, comprehensive solution. This includes SonicPoint wireless access points and the Dell SonicWALL WAN Acceleration Appliance (WXA) series, both of which are automatically detected and provisioned by the managing NSA firewall. Consolidating multiple capabilities eliminates the need to purchase and install point products that don’t always work well together. This reduces the effort it takes to deploy the solution into the network and configure it, saving both time and money. Ongoing management and monitoring of network security are handled centrally through the firewall or through the Dell SonicWALL Global Management System (GMS), providing network administrators with a single pane of glass from which to manage all aspects of the network. Together, the simplified deployment and setup along with the ease of management enable organizations to lower their total cost of ownership and realize a high return on investment
