Who we are?

HarfangLab is a cybersecurity scale-up that has developed an EDR (Endpoint Detection and Response) software, designed to prevent, detect and neutralize attacks targeting workstations and servers. In 2024, our solution has incorporated EPP (Endpoint Protection Platform) capabilities and monitoring tools to simplify IT infrastructure audits.

Since our founding in 2018, HarfangLab's technology has earned widespread recognition, winning prestigious awards and achieving the distinction of being the first ANSSI-certified EDR in 2020, followed by becoming the first to receive ANSSI qualification in 2025.

We have raised a total of €30 millions, enabling us to strengthen our teams and expand internationally across Europe. In just three years, HarfangLab’s workforce has nearly tripled, with the majority of its team members coming from technical backgrounds and dedicating themselves to R&D and continuous product enhancement.

Today, HarfangLab protects the endpoints of several hundred clients of all shapes and sizes, from CAC 40 corporations and government agencies to SMEs, hospitals, and local councils.

Driven by a strong sense of teamwork and global ambitions, HarfangLab continues to grow while staying true to its mission: to protect organisations from increasingly sophisticated cyber threats while ensuring that customers maintain full control over their data.
