Product Profile
Assured isolation with hardware-enforced one-way flow
Radiance™ Data Diode enforces unidirectional data movement in hardware - information can travel out of (or into) a protected enclave while the reverse path is made physically impossible. Built on fiber-optic media, it provides an assured airgap between networks of differing trust levels, so telemetry, logs, and sensor feeds can cross domains without ever exposing a return channel for an adversary to exploit.
Unlike software- or firewall-based controls, Radiance's one-way property is a physical characteristic of the device - there is no configuration, exploit, or misconfiguration that can open a return path.
Key capabilities
Hardware-enforced one-way transfer
Unidirectionality is a physical property of the device - no setting or attack can open a return path.
Fiber-optic airgap
Optical isolation maintains a true airgap between trusted and untrusted networks over fiber.
In-situ traffic analysis
Real-time packet capture and non-interactive active monitoring of the data crossing the diode.
Event-based reconfiguration
Self-reconfigures in response to detected events for an adaptive cross-domain posture.
Cross-domain data movement without a return path
Radiance™ is built for critical-infrastructure, OT/ICS, and high-assurance environments where information must move between trust domains under strict guarantees. It supports secure one-way ingest into protected enclaves and controlled, monitored exfiltration of telemetry to lower-trust networks - all while preserving a hardware-guaranteed airgap that no software path can defeat.
