The High Speed Verifier (HSV) enables secure bi-directional data transfer while enforcing protocol and data breaks to prevent malicious attacks. It utilizes Field Programmable Gate Array (FPGA) hardware logic for threat removal and data verification, ensuring no software vulnerabilities. The HSV supports multiple protocols and data formats, providing robust security for environments requiring high assurance, such as government and defense systems. It combines the simplicity of diodes with advanced features like bi-directional communication and is built into a 1U rack chassis with an LCD touch panel for ease of use. The HSV secures data transfer between segregated networks, including OT and IT environments, and cloud connections, ensuring data integrity and preventing malware infiltration through hardware-enforced security measures.
