Airbus has agreed to acquire French cybersecurity firm Quarkslab, marking its second such acquisition in under a month, to strengthen sovereign cyber capabilities for French authorities and European clients.
Airbus has signed an agreement to acquire Quarkslab, a privately-owned French cybersecurity company founded in 2011 and backed by Tikehau Capital since 2020, according to official disclosures. The transaction, expected to close in 2026 pending regulatory approvals and social partner consultations, will see Quarkslab’s approximately 100 employees based in Paris and Rennes integrate into Airbus Defence and Space’s Connected Intelligence business unit.
Quarkslab markets QShield, a solution protecting software against AI-driven threats and reverse engineering, particularly for defense and aerospace applications. This development matters because the acquisition follows another cybersecurity deal by Airbus Defence and Space within a month, signaling an accelerated consolidation strategy. By absorbing Quarkslab’s expertise in protecting critical assets and edge components, Airbus aims to build a “digital shield” for French and European sovereign entities amid rising state-sponsored and AI-enabled cyber threats. Industries impacted include defense, aerospace, and critical infrastructure cybersecurity.
Stakeholders include French government agencies, NATO allies, and European software providers seeking certified protection against reverse engineering.
For investors, the deal reflects growing demand for specialized, sovereign-aligned cybersecurity vendors, with Airbus leveraging acquisitions to reduce reliance on non-EU security providers. The integration of Quarkslab’s anti-AI threat capabilities may also create cross-selling opportunities within Airbus’s existing defense portfolio.
Airbus Defence and Space is a division of Airbus SE, specializing in military aircraft, space systems, and secure communications.
Quarkslab is a French cybersecurity firm founded in 2011, focused on software protection and anti-reverse engineering solutions.
