Airbus has acquired Quarkslab, a leading French cybersecurity firm, to strengthen its sovereign cyber capabilities in defense and aerospace. The move enhances Airbus’ end-to-end cyber portfolio amid rising threats to sensitive technologies.
Quarkslab specializes in offensive and defensive security solutions, including consulting, R&D, and software tailored for defense and space sectors. Its expertise addresses vulnerabilities in global supply chains and export compliance under French regulations.
The acquisition builds on Airbus’ recent UK expansion, where it agreed in March 2026 to buy Ultra Cyber Ltd from Cobham Ultra group. That deal, pending approvals for H2 2026 closure, complements existing operations in Newport, Wales.
Quarkslab’s focus on forcing attackers to adapt aligns with Airbus’ strategy to protect intellectual property from espionage and tampering. This positions Airbus as a key sovereign partner for European allies, securing operations in avionics, connectivity, and future aircraft systems.
The deal underscores France’s booming cybersecurity ecosystem, with over 100 startups driving innovation supported by ANSSI and Ministry of Defense initiatives. For Airbus, it ensures resilient cyber defenses critical to aerospace competitiveness.
