USB Firewall is an endpoint security solution that controls USB device usage and protects data transferred via USB drives. The product provides encryption and access control mechanisms to ensure files copied to USB drives can only be accessed within authorized environments. The solution addresses two primary security concerns: preventing malware introduction through USB devices and preventing data leakage when USB drives leave the organization. Files copied to USB drives from protected systems remain encrypted and unreadable outside designated locations. The product includes device whitelisting and blacklisting capabilities, allowing administrators to control which USB drives can be used on specific computers or departments. All USB file transfer activities are logged centrally for audit and compliance purposes. USB Firewall is designed for environments requiring secure data transfer between air-gapped systems, such as operational technology networks, critical infrastructure, and defense organizations. The solution enables secure transfer of files between internet-connected systems and isolated networks while maintaining protection against USB-borne threats. The product includes compliance reporting features to demonstrate USB security controls to auditors and regulators. It supports use cases including OT system updates, ATM maintenance, and secure data exchange with external parties such as vendors and partners.
