SonicWall TZ300/400/500/600 USB Security Clamp | Hardware Accessory

Add a physical layer of control to compatible SonicWall TZ appliances with this USB security clamp. Designed for TZ300, TZ400, TZ500, and TZ600 platforms, it helps restrict access to the USB interface in environments where device tampering or casual access is a concern. For branch offices, retail sites, and distributed network closets, small hardware details matter. A security clamp can reduce the risk of accidental disconnects and limit access to ports that should remain controlled. That makes it a useful addition when firewall appliances are installed in shared spaces, remote locations, or cabinets with broader physical access. This accessory is straightforward by design: it supports the appliance family it was made for and adds a simple layer of physical security without changing the firewall configuration or operational workflow. For procurement teams, that means a low-complexity item that fits neatly into standardized deployment kits. Choose it when the firewall is already doing the network security work and the goal is to tighten the physical perimeter around the hardware itself.
