Summary
Orange Cyberdefense will integrate a cyber version of Mistral Large 4, nicknamed "Le Chonk", into its security offerings for enterprise and public-sector clients. This open model, with 1,000 billion parameters and trained in Europe, is optimised for penetration testing, vulnerability assessment and red teaming; according to Mistral, it scores 51% on the Artificial Analysis Cyber Index. Orange plans to run these models on European computing capacity, in order to strengthen digital sovereignty and meet compliance requirements, processing source code, telemetry and incident logs without going through an external API. Orange Cyberdefense, whose 2025 revenue stood at €1.3 billion, did not disclose the financial terms of the agreement, which forms part of a broader partnership between Orange and Mistral formalised in 2025.
