Overview
Fend provides hardware devices that securely transfer data from connected equipment by using full optical isolation, sending data in one direction to block cyberattacks. The devices physically isolate the data channel and route data to cloud-based machine learning for analysis without allowing any reverse data flow. Unlike software-only security, Fend relies on hardware isolation and US-made manufacturing, targeting critical infrastructure like electric utilities, transportation, and HVAC with direct sales and government contracts. Its goal is to prevent cyber threats from reaching operational networks while enabling secure data analytics for decision making in essential systems.
