Next-Generation FirewallsNSa Series
Next-generation firewalls for distributed enterprises and data centres.
SonicWall NSa Series (Network Security Appliance) provides next-generation firewall protection for mid-size networks, distributed enterprises, and data centres. Powered by SonicOS with Reassembly-Free Deep Packet Inspection and the Capture ATP cloud sandbox, it delivers automated, real-time breach detection and prevention at scale. Faltrox deploys, configures, and manages it as the enterprise or data-centre perimeter.
Overview
What NSa Series is
The NSa Series is SonicWall’s mid-range-to-enterprise firewall line, sized for distributed enterprises and data centres that need higher throughput and scale than the TZ branch tier. It delivers automated, real-time breach detection and prevention with the multi-engine protection SonicWall is known for.
It runs SonicOS with Reassembly-Free Deep Packet Inspection (RFDPI) — inspecting every byte of every packet across all ports and protocols — and integrates the Capture ATP cloud sandbox with patented RTDMI, so malware’s weaponry is exposed and blocked in real time. Intrusion prevention, gateway anti-malware, application control, and TLS inspection run at the throughput a distributed enterprise or data centre needs, managed centrally through Capture Security Center or Network Security Manager. Faltrox deploys it, designs the segmentation and policy, and operates it as managed enterprise defence.
Coverage
What it protects
The platforms, threats, and surfaces this product is built to defend.
Distributed Enterprise & DC
Next-generation firewall protection for distributed enterprises and data centres.
Higher Throughput
More performance and scale than the TZ branch tier for busier networks.
Deep Packet Inspection
RFDPI inspects every byte of every packet across all ports and protocols.
Unknown Threats
Capture ATP with RTDMI exposes and blocks evasive and never-before-seen threats.
TLS Inspection
Inspects encrypted traffic at scale so threats cannot hide inside TLS.
Automated Prevention
Automated, real-time breach detection and prevention across the network.
How it works
The mechanism
How the product moves from signal to protected state, step by step.
- 01
Deploy
An NSa appliance is placed at the enterprise or data-centre perimeter and onboarded to Capture Security Center or NSM.
- 02
Inspect
RFDPI inspects every byte of every packet across all ports and protocols, including TLS-decrypted traffic.
- 03
Detonate
Suspicious files route to the Capture ATP cloud sandbox, where RTDMI forces malware to expose its weaponry in memory.
- 04
Block
Threats are detected and blocked in real time before they enter the network.
- 05
Operate
Faltrox designs the segmentation and policy, maintains SonicOS, and monitors the perimeter as managed defence.
Capabilities
Key capabilities
Reassembly-Free Deep Packet Inspection
Inspects every byte of every packet across all ports and protocols at low latency.
Capture ATP Sandbox
Cloud sandbox with patented RTDMI catches evasive, fileless, and never-before-seen threats.
Automated Breach Prevention
Automated, real-time breach detection and prevention across the network.
Intrusion Prevention
Blocks exploits and known attacks inline at enterprise throughput.
Gateway Anti-Malware
Multi-engine anti-malware blocks malicious files at the perimeter.
Application Control
Identifies and controls applications regardless of port for granular policy.
TLS/SSL Inspection
Decrypts and inspects encrypted traffic at scale so threats cannot hide in TLS.
Centralised Management
Managed through Capture Security Center or Network Security Manager.
Works with
Part of the platform
SonicWall products this pairs with, and the Faltrox services that operate it.
Delivery
You buy the outcome, not the console
Managed by Faltrox
Faltrox licenses, deploys, and tunes SonicWall NSa Series for your environment, then runs it as part of a managed service, so you get the protection without staffing another security console.
FAQ
Common questions
01Where does the NSa Series fit versus the TZ and NSsp?
The NSa Series is the mid-range-to-enterprise tier for distributed enterprises and data centres — above the TZ branch/SMB line and below the high-end NSsp for the largest enterprise and data-centre deployments. Faltrox sizes the model to your throughput and role.
02What is RTDMI and why does it matter?
Real-Time Deep Memory Inspection is SonicWall’s patented technology in the Capture ATP sandbox. It forces malware to reveal its weaponry in memory in real time, catching evasive, fileless, and chip-based attacks that traditional sandboxes — which watch behaviour over time — miss, and it blocks them in real time.
03Does it keep performance with full inspection on?
RFDPI is designed to inspect every byte of every packet without proxying or buffering, so it delivers deep inspection at low latency — the NSa Series is sized to sustain that at distributed-enterprise and data-centre throughput. Faltrox sizes the model to your needs.
04How is a distributed estate managed consistently?
Through Capture Security Center (cloud) or Network Security Manager, which manage the whole firewall estate from one console with shared policy — so many sites are operated consistently. Faltrox runs that management for you.
05How does Faltrox operate it?
We deploy and size the appliances, design the segmentation and threat policy, enable Capture ATP, maintain SonicOS, and monitor the perimeter — folding detections into the SOC services we run for managed enterprise defence.
