Benefits of the NSA firewall series


Cutting-edge threat prevention

NSA firewall series next-generation firewalls integrate two advanced security technologies to deliver cutting-edge threat prevention that keeps your network steps ahead of cyber-threats.


RTDMI technology

Our Real-Time Deep Memory Inspection (RTDMI™) technology engine proactively detects and blocks mass market, zero-day threats and unknown malware by inspecting directly in memory. Due to its real-time architecture, SonicWall RTDMI technology is highly precise. This ensures it minimises false positives, and identifies and mitigates sophisticated attacks where the malware’s weaponry is exposed for less than 100 nanoseconds.

RFDPI technology

SonicWall’s single-pass Reassembly-Free Deep Packet Inspection (RFDPI) engine examines every byte of every packet, inspecting both inbound and outbound traffic on the firewall. By leveraging the SonicWall Capture Cloud Platform in addition to on-box capabilities including intrusion prevention, anti-malware and web/URL filtering, the NSA series blocks even the most insidious threats at the gateway.
