WXA 4000 WAN Acceleration Appliance

The SonicWALL® WAN Acceleration Appliance (WXA) 4000 reduces application latency and conserves bandwidth, significantly enhancing WAN application performance and improving the end user experience for distributed organizations with remote and branch offices. Unlike standalone acceleration products, the SonicWALL WXA 4000 seamlessly integrates with SonicWALL E-Class Network Security Appliance (NSA), NSA and TZ Series Unified Threat Management (NGFW) Firewall solutions to offer the unique combined benefit of both prioritizing and minimizing application traffic between sites, resulting in optimal network performance.


The WXA 4000 hardware appliance improves application performance through innovative WAN acceleration and optimization technology, allowing remote users to collaborate, share and revise large files more effectively and efficiently.

Powerful performance.
With 4 GB of RAM and two 250 GB hard drives in a RAID configuration, the WXA 4000 can support up to 240 users and 1,200 concurrent flows on a single appliance.

Bandwidth optimization.
The WXA 4000 remembers data that has been transferred previously, and through data de-duplication, replaces repeated byte sequences with an identifier to reduce application latency and conserve bandwidth.

Simplified deployment.
As an add-on solution to SonicWALL NGFW firewall appliances, the WXA 4000 drastically reduces the complexity of deploying, routing and managing the WXA appliance.

Reduced total cost of ownership (TCO).
By improving the efficiency and overall utilization of existing WAN bandwidth, the WXA 4000 helps businesses avoid incurring higher monthly expenses to increase WAN bandwidth capacity.

Data compression.
The WXA 4000 increases network performance while reducing latency by compressing data sent across the WAN.
