8.4.2022: Airbus Defence and Space acquires DSI Datensicherheit GmbH

Today we had the closing of the M&A Process for the acquisition of 100% shares of our daughter company DSI Datensicherheit (DSI-DS) by Airbus Defence and Space (ADS). Our daughter company DSI-DS is a specialist for crypto and tempest solutions in aerospace applications. This acquisition by one of our main customers provides in our view a perfect match in order to support the rapid growth of DSI-DS in a challenging market. Our other daughter company DSI Aerospace Technology is not affected by this acquisition and remains a SME as a full daughter of the DSI Informationstechnik GmbH.

DSI Datensicherheit GmbH will be rebranded by the new owner to avoid confusion with the other companies of the DSI Group.



DSI Informationstechnik GmbH is a SME located in Bremen, Germany, providing high-end electronics for airborne and space applications. Founded as a spin-off of the University of Applied Sciences Bremen in 1997 by Professors Dr H. Michalik and Dr L. Hinsenkamp, DSI has continued to deliver future-oriented solutions since that time in terms of both aerospace technology and IT security systems.

The fields of activity are dedicated to the engineering, development, manufacturing and qualification of solutions for aerospace electronic equipment, information technology and advanced communication systems. We are specialised in designing digital systems, which provide significant savings in required resources in terms of power consumption, mass and volume. At the same time, our integrated approach provides significant increases in processing power as well as in reliability due to the usage of the newest, qualified FPGAs and ASICs technologies.

The DSI group currently comprises three independently-operating companies:

  • DSI Aerospace Technologie GmbH
    (DSI-AS, locations: Bremen & Braunschweig) provides dependable electronics for space, airborne and terrestrial platforms
  • DSI Datensicherheit GmbH
    (DSI-DS, location: Brinkum) provides dependable and accredited solutions and equipment for IT-security applications
  • DSI Informationstechnik GmbH
    (DSI-IT, location: Bremen) acts as a holding company for DSI-AS and DSI-DS



Our mission:
We provide outstanding expertise in the design, implementation, production and qualification of dependable electronics. DSI combines high-end technologies and innovative ideas into ­cutting-edge products. Innovation, Performance and Quality are our daily drivers for ensuring mutual success together with our customers.

Our claim:
The customer’s satisfaction is the central element of DSI’s success. We are ­challenged by our partners worldwide to create tailored technology ­solutions in response to their state-of-the-art applications’ needs. We stand for the ­dependability of our products as well as our offered ­services. Our promise to you is a dedication to high quality, on-time delivery and cost effectiveness.

Our values:
We achieve our claims through clearly-stated values within the company and in our interactions with our customers. DSI’s internationally diverse team is guided by visionary thinking and the aim of excellence in working. We are ­open-minded and we practice respectful collaboration both within and outside of the company.

DSI provides products for institutional and commercial applications in the ­following domains:

  • Space (e.g. on-board electronics for satellites, space probes and space robotics) 
  • Air (e.g. on-board electronics and crypto systems for UAVs) 
  • Ground (e.g. secure IT equipment, ground station components, EGSE)
