Owl 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. The product is specifically 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 minimal support and maintenance, making it suitable for distributed deployments across multiple locations. The hardware-enforced one-way data flow prevents any possibility of reverse communication, ensuring that sensitive networks remain isolated from potential threats while still allowing necessary data to flow outward. The product was designed for OT environments where network segmentation and secure data transfer are critical requirements. Its compact form factor enables deployment in space-constrained environments typical of industrial and operational technology settings. Note: Due to supply chain shortages, production of DiOTa has been indefinitely halted and the product is no longer available for sale. Owl Cyber Defense recommends the OPDS-1000 as an alternative with similar operational characteristics.
