About Quarkslab
Quarkslab is a cybersecurity company that offers three main solutions. QRedTeam simulates sophisticated attacks against information systems. QLab conducts deep security research on products and applications. QShield protects software code when it runs outside the owner's control. These services are built on offensive research that Quarkslab carries out continuously. The company serves clients in sectors where failure is not an option, including defence, space and aeronautics, automotive, finance, critical infrastructure, healthcare, and big tech. It operates in 22 countries across four continents, with offices in Paris, Rennes, and Buenos Aires. Since 2026, Quarkslab has been part of Airbus Defence and Space. What sets Quarkslab apart is its research model. Forty per cent of its engineers' time is dedicated to research without client constraints. This work produces public results such as CVEs, open-source tools, and conference talks. The company has a team of around one hundred experts, including many PhDs.
