Benefits at a glance
1. Security
The Siemens DCU ensures the highest security using proven technology. To
date, there hasn’t been a single case of industry grade data diodes being
bypassed or breached by outside threats. By creating a physical break and
hardware enforced one-way data, the DCU eliminates the risk of external /
internet-based attacks affecting critical networks for which 100% security can
be achieved. The solution has also proven to be one of the most reliable on
the market with the highest MTBF (mean time between failures) combined
with extensive product support from Siemens.
2. Connectivity
The Siemens DCU ensures seamless connectivity between your IT and OT
networks. In this case, it functions as vendor neutral bridge that supports all
main industrial protocols. Using the DCU, you can collect data from your OT
networks (such as from plant SCADAs, for example) and push data to corporate
IT networks or to the cloud. The DCU offers direct connectivity to MindSphere,
Microsoft Azure and Amazon Web Services, amongst others. The DCU is also
compatible with 3rd party applications, which can be scaled to meet any need.
3. Compliance
The Siemens DCU does more than just keep your critical networks secure – it also
helps ensure cybersecurity compliance. Every major cybersecurity guideline
recommends the use of data diode technology to reduce the risk of systems
or user data being exploited. The DCU was also designed to comply with
internationally recognized security standards such as IEC 62443. Thanks to
its non-routable IP to IP communication, the DCU even meets US NERC CIP’s
(Critical Infrastructure Protection) requirements for isolation.
