DiOTa is a single-purpose and compact data diode cybersecurity device designed to provide deep and scalable security for digital assets in the rapidly growing Industrial Internet of Things (IIoT).


Edge Security for Operational Technology and the IIoT

DiOTa can perform a hardware-enforced one-way transfer and is built on a hardened OS hardware platform, supporting one data flow or protocol at a time with a maximum throughput of 5 Mbps. The device can secure operational technology (OT), micro-segmentation applications, and network boundaries both on site and at remote locations in multiple deployments and requires minimal support and maintenance.

Simple, Compact, and Intuitive

Set up and configuration of DiOTa is straightforward and fast. The device can be configured and ready to perform a secure data transfer within minutes. The combination of the Quick Start Guide (provided with the device) and DiOTa’s intuitive, web-based user interface makes navigating tasks quick and easy, saving you time and guesswork. DiOTa’s economical price, ease-of-use, and small form factor make it a smart solution for multiple deployments.
