Blocks More Attacks With RTDMI

Real-Time Deep Memory Inspection (RTDMI) proactively detects and blocks unknown malware via deep memory inspection in real time, a revolutionary approach to defend against zero-day and side-channel attacks and other unrecognized threats.

Secure Remote Workers

SonicWall NetExtender provides an intuitive SSL-VPN connection client that's easy to deploy and configure. Easily provide your remote workers with secure access to your corporate network from Linux, Mac and Windows devices.

Secure SD-WAN Technology

Leave MPLS behind for a more agile, more secure and more cost-effective network optimized for today's broadband-driven, cloud-infused landscape. Secure SD-WAN technology is built in to NSa firewalls, so there's no need to purchase additional SD-WAN appliances and licenses.

Built-in Wireless Controller

Implement high-speed wireless security by combining a NSa series next-generation firewall with a SonicWall SonicWave wireless access point. NSa series firewalls and SonicWave access points both feature 2.5 GbE ports that enable multi-gigabit wireless throughput offered in Wave 2 wireless technology.

Low Total Cost of Ownership

Make a SonicWall NSa firewall the start of enterprise savings. From reduced costs through zero-touch deployment to enabling SD-WAN and delivering NetSecOPEN-verified threat block rates on par or better than competitors at a fraction of the cost, SonicWall NSa firewalls are security you can't afford to be without.

Cloud-based & On-Premises Centralized Management

Gain greater visibility into your enterprise even as it becomes more complex on- and off-prem. Tightly integrated into the SonicWall ecosystem, bring your firewalls into a single-pane-of-glass management, licensing, reporting and analytics

High Performance and Port Density
