What is a Data Diode?

A data diode is a device that allows information to travel in only one direction.  Data diodes physically transport data in a one-way fashion, rather than relying on software and code like more vulnerable firewalls and threat detection systems.

Protect Equipment and Networks

Stream data from industrial control systems or transfer files between networks in a physically-enforced, one-way fashion. Learn more about what you can do with a data diode.

Why Fend?

Fend’s hardware establishes traditional two-way communication with data sources and end destinations, while on-board processors transmit data from the protected side to outbound side in a unidirectional manner. No need for custom external servers or software. Built from the ground up as a cost-effective solution for monitoring industrial equipment. Made in the USA.

Fend Cloud

Use the power of remote monitoring or cloud-based analytics to provide the operational awareness and intelligence your teams need to more efficiently achieve your mission and improve resilience.
