The Everfox High Speed Verifier (HSV) is a high-assurance cross-domain security solution designed to safely move data between networks of different classification levels. It provides a physical “protocol break” and data verification enforced by hardware logic, allowing secure bi-directional communication across air-gapped networks without exposing the target system’s attack surface.
The system is developed by the cybersecurity company Everfox (formerly Forcepoint Federal). It is primarily deployed within mission-critical infrastructure, defense networks, intelligence platforms, and top-secret government facilities. Core Technology & Features
Unlike standard software-based firewalls, the High Speed Verifier handles security boundaries at the physical and logic layers:
Hardware-Enforced Protocol Break: Standard network protocols (like TCP/IP) are stripped down by software proxies at the boundary. The data is then streamed across the internal verifier using a raw Ethernet protocol enforced purely by hardware logic. This ensures no network-layer software threats can bypass verification.
FPGA Logic Verification: The HSV uses Field Programmable Gate Array (FPGA) hardware logic to structurally inspect and verify data. Because the verification rules are burned into hardware circuits, it acts at a speed and level of security that traditional software cannot match.
Bi-Directional Safety: Traditional data diodes restrict information to a strict, physical one-way flow. The HSV enables dual, secure, two-way communication. It hides the destination server’s architecture, effectively creating a shield against reverse exploitation.
Built-in Threat Removal: The HSV pairs natively with content disarm and reconstruction (CDR) technologies. It sanitizes data envelopes and structural payloads (such as XML, JSON, or complex files) before allowing them through. Available Form Factors
