CYSAT ’23, a space cybersecurity conference : Full Keynotes and Presentations


CYSAT ’23 is the first conference in Europe dedicated to satellite and space industry cyber security. It took place from 26 to 27 April 2023 and brought together key players from the European space industry to share challenges and solutions related to cyber risks and cyber security in space.

Faced with cybersecurity challenges and the growing importance of data protection in space, it is crucial to bring together communities of cybersecurity experts to build a European ecosystem capable of addressing current and future industry challenges.

Last years’ event saw more than 450 space specialists, decision-makers and experts come together. In its third year, CYSAT will highlight Europe’s cybersecurity capabilities and solutions dedicated to space from both a technological and geostrategic perspective.

What you will watch:

  • An exclusive testimony by Colonel Oleksandr Potii, Deputy Chairman of the State Service of Special Communications and Information Protection of Ukraine. A year since the cyber-attack on satellite network KA-SAT, Potii will reflect on what lessons can be learned from this attack.
  • Talks and keynotes from renowned industry experts, including Philippe Baptiste, President of CNES, Jean-Marc Nasr, Vice-President Space at Airbus Defence and Space, Massimo Mercati, Head of Security at ESA and Greg Wyler, founder of E-Space.
  • Workshops and demonstrations highlighting the know-how of the space industry

Opening of CYSAT 2023 with Lionel Suchet from CNES

Space is the new frontier of cybersecurity. The growing amount of space data collected and processed in the cloud makes cybersecurity a fundamental topic. CYSAT 2023, as the biggest European event dedicated to space cybersecurity, paved the way to a whole new set of reflexions within the European context.

As the COO of CNES, the French government space agency, Lionel Suchet was appointed Director of Innovation, Applications and Science. This new directorate (DIA) is tasked with supporting the interests, requirements and challenges of all potential users of space data and missions, and planning and proposing CNES’s future orbital systems with a view to nurturing creativity and driving innovation.

Hack CYSAT 2023 – World premiere: hacking and recovery of a flying satellite

For the third edition of CYSAT, the biggest European event entirely dedicated to cybersecurity for the space industry, taking place on 26-27 April 2023 at Station F in Paris, the European Space Agency (ESA) set up a satellite test bench to simulate attempts to seize control of OPS-SAT, a nanosatellite operated by the agency for demonstration purposes.

Thales’s offensive cybersecurity team stepped up to the challenge, identifying vulnerabilities that could enable malicious actors to disrupt operation of the ESA satellite.

Thanks to ESA and Thales for their hacking demonstration and involvement to raise awareness on cybersecurity risks in the space industry.
