Secure OT-to-IT middleware, guaranteed one-way by physics.

Powered by OTDataMule software

Diodos converts, normalizes, and moves plant data from protected OT networks to IT, analytics, and compliance systems through a hardware-enforced one-way path. Visibility goes out. Risk does not come back in.

Zero inbound path Physical one-way transfer from OT to IT.
Protocol middleware Convert OT sources into IT-ready data streams.
Two clear models Up to 100 or 10,000 tags per second.
South / OT Collector Reads trusted operational data from the protected side.
North / IT Forwarder Delivers clean outbound data to enterprise systems.

A middleware layer with a hard physical boundary.

Firewalls depend on software rules. Diodos combines protocol conversion with a one-way optical path, with OTDataMule software handling outbound data movement, so there is no return channel for sessions, commands, credentials, or remote access back into OT.

Protocol conversion for historians, analytics, SOC teams, and auditors.
No inbound network route into the protected OT side.
Designed for sites that need mapped, IT-ready data without opening the plant.
South / OT Collects operational data at the plant side.
North / IT Receives and forwards data to business systems.
One-way optical transfer. No return path.

What buyers get from secure OT middleware.

Diodos is positioned for teams that need protocol conversion, operational visibility, regulatory reporting, and enterprise data access without turning IT connectivity into OT exposure.

Reduce inbound attack surface

Replace risky two-way routes with a physical outbound-only data path.

Convert protocols cleanly

Collect from OT systems, normalize the data, and deliver it in formats enterprise systems can use.

Make risk simple to explain

A physical one-way link is easier to communicate to boards, auditors, and plant leadership.

Convert OT protocols into IT-ready destinations without opening a return path.

Diodos acts as secure middleware between industrial sources and enterprise systems. OTDataMule software maps and forwards the data flows, with clear separation between the South / OT side and the North / IT side.

South / OT side

Collect and normalize data from plant systems before one-way transfer.

Industrial sources
OPC UA OPC XML-DA Modbus Ethernet
Messaging
MQTT Broker MQTT Client
Files and databases
CSV / Tabular files MS SQL Server Oracle PostgreSQL MySQL

North / IT side

Convert and deliver validated outbound data to enterprise, historian, and reporting systems.

Historian and analytics
PI OMF PI System Data lakes
Messaging and APIs
MQTT Web API SFTP
Files and databases
CSV MS SQL Server Oracle PostgreSQL MySQL

Choose the model that matches your data flow.

Both models use the same middleware architecture: a South / OT computer, a North / IT computer, OTDataMule software for protocol handling, and fiber optic transfer in the middle.

Diodos Small

For edge deployments, pilots, and focused protocol conversion needs.

100tags / second
  • Compact deployment scope
  • Fast proof of value
  • Same physical one-way protection

Diodos Plant

For high-throughput plant-wide middleware, visibility, and enterprise reporting.

10,000tags / second
  • Designed for large operational environments
  • Built for continuous data delivery
  • Same physical one-way protection

Built for environments where inbound paths are unacceptable.

Use Diodos wherever production data must be converted and leave OT, while control networks remain sealed from enterprise traffic.

Energy and utilities

Outbound telemetry for reporting, market operations, analytics, and oversight.

Manufacturing

Line and plant data to MES, ERP, quality, and business intelligence systems.

Pharma and chemicals

Batch records, compliance exports, and production visibility without inbound exposure.

Water and wastewater

Operational telemetry for monitoring and reporting while protecting critical control assets.

Mining and transit

Remote operational data delivery where resilience and isolation matter.

Government and defense

Outbound data movement for sensitive environments with strict separation requirements.
