Rust Engineer - Cybersecurity

Who we are?

HarfangLab is a cybersecurity scale-up, and we have developed an Endpoint Detection and Response (EDR) software to detect and mitigate modern cyberattacks on a company's workstations and servers. Our algorithms detect abnormal behaviors and generate security alerts or block program execution.

From 18 to 90 employees in 2023, HarfangLab is experiencing hypergrowth and has already achieved several significant milestones: winners of the Ministry of Defense's cyber challenge in 2019, recipients of the BPI's I-Nov competition in 2020, and software certified by ANSSI in 2021.

Our initial clients include CAC40 industrial companies and government entities. We completed our first funding round of €5 million in 2021 and our second funding round of €25 millions in 2023, which will enable us to strengthen our teams, and to expand internationally in Europe.

Our mission is to protect businesses and government agencies from modern cybersecurity threats (cybercrime, data theft, influence) that endanger the economic health of companies and the security of the nation.

Notre ambition est de protéger les entreprises et les administrations étatiques face aux menaces informatiques modernes (cybercriminalité, vol de données, influence) qui mettent en danger la santé économique des entreprises et la sécurité de la Nation.
