SonicWall SMA 400 Hardware Appliance | Application Firewall, 25 U Licenses

Deliver controlled remote access for users who need to reach internal applications without exposing the broader network. The SonicWall SMA 400 hardware appliance pairs application firewall protection with a compact, rack-ready design and 25 user licenses, making it a practical fit for smaller secure access deployments and branch-level use cases. With Gigabit Ethernet connectivity, USB support, and a manageable hardware platform, this appliance is built for teams that need a dedicated access gateway rather than a general-purpose server. Its 1U chassis keeps rack space requirements low, while the 11 lb footprint and 10.1 in depth make it straightforward to place in constrained network closets. For organizations that value tighter control over remote access paths, the SMA 400 helps centralize policy enforcement and reduce reliance on ad hoc VPN approaches. It is a purpose-built option for environments where secure application access, predictable administration, and license-defined user coverage matter more than broad feature sprawl.
