Airbus leads cyber M&A surge with Quarkslab AI defence deal

Thirty-three cybersecurity-related merger and acquisition deals were announced in April 2026, including Airbus to acquire Quarkslab, Cyera acquiring Ryft, Everfield acquiring Rhebo, Fortra acquiring Zero-Point Security, Palo Alto Networks to acquire Portkey, Silverfort acquiring Fabrix Security, Socket acquiring Secure Annex, Spin[.]AI acquiring Revyz, and other deals listed in SecurityWeek’s roundup.

The Airbus-Quarkslab deal is described as part of Airbus’s broader strategy to build sovereign cybersecurity capabilities across Europe, with Quarkslab’s QShield solution aimed at defending against AI-driven threats and reverse engineering. Cyera, valued at about $9 billion, is expanding its agentic AI security focus with the Ryft acquisition, while Fortra’s purchase of Zero-Point Security enhances offensive security training capabilities.

Other notable moves include Palo Alto Networks’ intent to secure Portkey to govern autonomous AI agents within Prisma AIRS, and Silverfort’s deal to bring Fabrix’s AI decisioning engine into its autonomous identity security platform. The roundup also notes additional transactions such as Socket’s acquisition of Secure Annex and Spin[.]AI’s acquisition of Revyz, among many others in April 2026.
