eLock USB Lockdown

In secure environments, open USB ports present a significant vulnerability, allowing connection of unauthorized devices like removable storage or network adapters. HSL’s USB HID Filters provide an essential layer of physical security by ensuring only authorized Human Interface Devices (HIDs) like keyboards and mice can connect to a target system.

Acting as a secure in-line gateway, the filter physically blocks all non-HID traffic, effectively neutralizing threats from unapproved peripherals. This straightforward hardware solution requires no drivers or software, offering immediate, transparent protection for any PC, server, or KVM system.

Prevent Data Breaches: Block unauthorized storage devices to prevent data exfiltration and malware injection via USB.
Enforce Security Policy: Help meet stringent government and corporate security mandates by restricting peripheral access to HID-only.
Universal Application: A simple plug-and-play solution that protects any computer or system with a USB port.
Transparent to Users: Operates invisibly without impacting the performance of approved HID peripherals.

Special Application: Resolving NIAP PP4.0 KVM Compatibility

Beyond standard port security, eLock HID filters such as the FH10NN-4 are crucial for solving a common installation challenge with high-security KVMs. NIAP PP4.0 certified KVM switches often reject complex HIDs (like keyboards with CAC readers or touchscreens) due to their built-in hub functionality. By placing a filter in-line, the hub signal is stripped, ensuring seamless compatibility and maintaining full security compliance.
