MODULAR CROSS DOMAIN SOLUTIONS

Physics doesn’t patch.

It prevents.

For 25 years, Sphyrna Security has built one thing: cross domain assurance. We design modular solutions — from OEO Diodes to FPGA Protocol Filtering Diodes and the high-volume raw data transfer, Diode Array — new capabilities in the pipeline.

All designed in-house through Sphyrna Labs, not acquired. Every product and research initiative we rigorously engineer and relentlessly validate is dedicated to pushing this one discipline forward.

UGW-200 · PROTOCOL FILTERING DIODE 1U · EIA 310-D

Sphyrna UGW-200 protocol filtering diode

Common Criteria EAL 4+

25 Years in Cross Domain

10 Gbps – 400 Gbps Aggregate

THE PRINCIPLE

One Way.

On Purpose

Software-based controls depend on correct configuration and current patching. Our diodes don’t. The return path is absent at the hardware layer — there is no channel for data to travel back into the protected network.

From 10 Gbps to 400 Gbps aggregate, hardware-enforced one-way transfer holds at every speed. NSA-Approved on UGW-100 and UGW-200, Common Criteria EAL 4+ across the line — verified, not assumed.

Hardware-enforced unidirectionality, not software-mediated
Optical-electrical-optical isolation across every product line

SPHYRNA CROSS DOMAIN SECURITY PORTFOLIO

Four Product Lines.
