Security critical supervision systems are exposed to an increasing number of threats, which have deep consequences in domains such as energy, transport, and defense.
It is crucial to build components that can better resist such threats.


Systerel implements a secure and open-source OPC UA Toolkit

  • EAL4+ security level
  • High assurance (formal methods)
  • Compliant with safety standards (IEC 61508 SIL2)
  • Specific design for embedded systems
  • Open-source (sources available here)
  • Security certification by ANSSI (French National Agency for Computer Security) planned in 2019

The next standard for industry 4.0 interoperability: OPC UA

OPC UA ? Open Platform Communications Unified Architecture

OPC UA is a standard overseeing interoperability and data exchange for industrial communications. It provides safe and secure means to connect supervision systems (SCADA) with programmable logic controller (PLC), actuators, and field systems.

  • International standard (IEC 62541)
  • Open, independent from manufacturers, programming languages, and operating systems
  • Secure and reliable: secure communications on open networks
  • Interoperable, multi-platform, upgradeable
  • Model Based, Object Oriented technology
  • Pub/Sub communication model

OPC UA: the choice for Industry 4.0 and IIoT (Industrial Internet of Things)

The German federal office for information security (BSI) evaluated OPC UA positively.
In its architecture benchmark (RAMI 4.0), the German platform for Industry 4.0 made OPC UA mandatory for the “communication” layer.

In France, the OPC foundation works with the normalization group of the Alliance pour l’Industrie du Futur to define its own reference model.

The OPC foundation

The OPC foundation is an international organization which promotes and maintains the OPC standards. The foundation gathers more than 500 members, from automation system providers to end users.
Systerel is a member of the OPC foundation.
