What's New


Single Purpose. Endless Applications.

Data diodes are going mainstream. Traditionally, Owl Cyber Defense (Owl) data diodes are deployed at the edge of the operational technology (OT) environments, for the easy, simultaneous transfer of SIEM and other data. However, as endpoints are rapidly proliferating and organizations are implementing segmentation and micro-segmentation, a lower cost, easy-to-deploy data diode is in demand.

Owl is proud to introduce the Owl DiOTa data diode, a single-purpose cybersecurity hardware solution. This hassle-free data diode secures digital assets, network segments, Internet of Things (IoT) devices, Industrial Internet of Things (IIoT), and the network boundaries both on site and at remote locations.

Owl Scowt-Compact™

Flexible. Rugged. Reliable.

The Owl Cyber Defense Solutions (Owl) Scowt-Compact is a ruggedized solution for airborne, ground, and naval assets, as well as forward-operating bases and remote command stations that need to transmit, stream, and receive data at different security levels on protected networks. In Defense, Intelligence, and other sensitive Government operations, data streaming and file transfer dataflows are crucial components of any successful mission or organization. Whether the dataflows are for the collection of sensor output and information reports, or the dissemination of command and control, alerts, and tips - the dataflows must be protected.



What Exactly is a Data Diode?

Data Diodes Protecting Our Way of Life

A piece of hardware that physically enforces a one-way flow of data. Most people think of data communications as requiring a two-way path, but most data can be transferred and shared over a one-way path. As one-way data transfer systems, data diodes are used as cybersecurity tools to isolate and protect networks from external cyber threats and prevent penetration from any external sources.

Owl Technology

OPDS Product Line

Data diodes are hardware based, bound by the laws of physics and not susceptible to zero day vulnerabilities or any other hacks. These solutions are data and network agnostic, have been deployed across a range of industries and are recommended by the Department of Homeland Security

Being data agnostic we can move files, streaming video, TCP/IP, UDP, database records, historians, sensor data, high-res images, system backups, personnel records and many other types of data; along with industrial protocols like Modbus and OPC.  And our network independence lets us work on unclassified, secret and top secret networks for government solutions and IT and OT (Operations Technology) networks for our commercial and industrial customers.

We offer all-in-one solutions with a standard 19” 1U rackmount form factor and a DIN rail form factor for industrial environments.  We also offer server based solutions that utilize off-the-shelf servers populated with our data diode cards.

Designed to be scalable, new software licenses and modules allow end-users to increase bandwidth, add-on new interfaces, and support new protocols.
