DiOTa is a compact, single-purpose data diode designed to provide secure, one-way data transfers from a source to destination, without exposing the secure network to risk. Designed to be deployed at scale to secure operational technology (OT) networks, micro-segmentation applications, and network boundaries (both on-site and at remote locations), DiOTa requires little to no support and maintenance.

Use Case

Easy to Configure & Deploy

DiOTa can be setup and deployed in under an hour. No complex configurations or expertise required. Once the device is received, turn it on, plug in the ethernet cables, and simply follow the setup wizard to enter your source and destination IP addresses, the protocol you will be using, as well as the port number. It’s as simple as that.

DiOTa Pricing

Are you still under the misconception that data diodes are one of the most expensive network security solutions in the marketplace? Compared to industrial firewalls, DiOTa provides a higher level of security and assurance at a comparable cost, requiring much less maintenance and support over its lifetime. Protect industrial devices at scale with hardware-enforced security, at an affordable cost, with a lower TCO.
