Account Manager - Cybersecurity

Who we are?

HarfangLab is a French cybersecurity scale-up developing a unified platform powered by a single lightweight agent and AI built for cybersecurity. Continuously enhanced through R&D, our portfolio includes EDR (Endpoint Detection and Response), EPP (Endpoint Protection Platform), ASM (Attack Surface Management), ITDR (Identity Threat Detection and Response), and Email Security, with the latter two joining the platform in 2026. Together, these solutions detect and neutralize threats across endpoints, servers, identities, and email environments. Our engines, models, and algorithms identify abnormal behaviour, generate security alerts, and block malicious activity.

Founded in 2018, HarfangLab has earned strong industry recognition: its EDR was the first to be certified by ANSSI in 2020, the first to obtain ANSSI qualification in 2025, and the first EDR to receive BSI certification in Germany. We also joined the French Tech 2030 programme, alongside 80 innovative French companies, as cyber resilience becomes a strategic priority for Europe.

Backed by €30 million in funding, we have grown from 40 employees in 2023 to 140 today and expanded internationally across Europe.

HarfangLab now protects the endpoints of more than 1,000 clients across all sectors, including CAC 40 industrial companies, government entities, SMEs, hospitals, and local authorities. Driven by a strong collective spirit and international ambitions, we remain committed to our original mission: protecting organizations against increasingly complex cyber threats while enabling them to retain full control over their data.
