Strong throughput - enterprise-grade security – no complexity.
SonicWall’s NSa Series delivers robust, enterprise‑grade protection without the complexity typical to large datacentre solutions. Built for organisations that need strong and reliable security, it defends against everything from routine intrusion attempts to sophisticated ransomware campaigns, while maintaining smooth and responsive networking.
NSa firewalls pair high‑density connectivity with advanced security capabilities such as intrusion prevention, malware analysis, secure SD‑WAN and intelligent application control. Featuring modern, resilient hardware architecture and multi‑gigabit throughput — even when inspecting encrypted traffic — it gives businesses the confidence to operate at full speed without compromising safety.
Powered by SonicOS 8, the NSa Series offers an intuitive interface that streamlines policy creation, deployment and daily administration. Integrated switch and access point management provides a unified view of the entire network, reducing operational overhead. Centralised management, Zero Trust support and flexible licensing simplify deployment and scaling, while built‑in redundancy and dual power options help ensure continuous uptime.
Flexible licensing options and Zero‑Trust‑aligned access via Cloud Secure Edge Connector round out a streamlined, centrally managed solution built for evolving enterprise networks.
With access to advanced technologies like cloud‑based sandboxing and deep memory inspection, NSa firewalls deliver comprehensive protection against zero‑day and encrypted threats — a secure, future‑ready foundation that keeps your business moving.
Who is it for?
The SonicWall NSa Series Appliance range is designed to meet the needs of businesses of all sizes - from medium to large enterprises through to distributed offices and SMBs.
Equipped with advanced inspection capabilities and integrated threat intelligence, combined with modern hardware performance, the NSa Series secures the internet edge and enables SD‑WAN‑driven ranch connectivity.
Support for secure SD‑WAN, high‑availability design, and simplified, unified administration makes them well‑suited to any organisation adopting Zero Trust or centralised security management.
At the perimeter, it delivers high‑performance inspection — including TLS 1.3 — alongside integrated threat protection and simplified central management.
For distributed sites, it provides secure, direct internet access, improved application performance when connecting to headquarters or cloud services, and strong defence against encrypted attacks, all backed by high‑density connectivity for wide‑area networks.
IDEAL FOR medium and large enterprises, distributed enterprises, campus environments, and branch networks,
How to choose your firewall:
A simple way to choose the right SonicWall NSa firewall is to base your expectations on real‑world performance rather than ideal lab figures.
Using the published TLS/HTTPS throughput and dividing it by three gives a realistic estimate of how the appliance will perform under heavy load with full security enabled, helping ensure it can comfortably exceed your internet speed.
For example, a firewall rated at 800 Mbps TLS/HTTPS would deliver roughly 270 Mbps in demanding conditions, with higher speeds possible if fewer security services are enabled.
