Developed for Protection Level 1 Nuclear programs, PSG gives every sensor, reader and camera at a nuclear or DOE site a trusted device identity and verified data at the source.
The standard is highest here. The edge is still analog.
Nuclear and DOE sites run some of the most demanding physical security programs in the country. Yet at the fence line and the vault door, many sensors, readers and cameras still report over supervised loops and analog links that authenticate nothing. A loop can show that a circuit changed. It cannot prove which device changed it.
Material protection, control and accounting depends on data that is trusted before an operator or an automated response acts on it. The work is to bring cryptographic identity to the devices already installed, in step with certification and outage schedules: modernization without rip-and-replace.

Where PSG sits
PSG is the Embedded Zero Trust Architecture for Physical Security. At a nuclear or DOE site it works in two layers: authenticated devices at the edge, and operations acting on verified data.

How PSG applies
Certified for PL1N
LINX 10 Enterprise is certified Protection Level 1 Nuclear by the U.S. Air Force for access control and intrusion detection. VICADS V100 carries federal certifications for Protection Levels 1 to 4 and Risk Management Framework Authority to Operate.
Authenticate every input
DESI replaces the end-of-line resistor at each sensor and output with a cryptographic identity. The panel accepts an input only after the device proves it sent it, and executes an output only after the command is verified.
Modernize between outages
Existing wiring, sensors and door hardware stay in place. A site moves to Zero Trust input by input, aligned with maintenance windows and budget cycles, so the protective system keeps running while it modernizes.
