Customer Success Manager - Cybersecurity in Paris

Who we are?

Harfang Lab is a leading European cybersecurity scale‑up focused on securing endpoints against modern cyber threats.

Since our founding in 2018, we have become a recognized innovator in endpoint protection, with our flagship EDR (Endpoint Detection and Response) solution continuously enhanced with cutting‑edge detection, investigation, and response capabilities.

Building on this strong foundation, our portfolio has expanded significantly.

We introduced Harfang Lab Guard, a unified security offering that combines EDR and EPP (Endpoint Protection Platform) to provide comprehensive protection, automatic threat blocking, and optimized analyst workflows.

More recently, we launched Scout, an integrated Attack Surface Management (ASM) solution that enables organizations to proactively identify vulnerabilities, shadow IT, and configuration gaps — all within the same agent and platform used for endpoint security.

Harfang Lab's technology has earned widespread recognition and achieved the distinction of being the first ANSSI (National Cybersecurity Agency of France) certified EDR in 2020, followed by becoming the first to receive ANSSI qualification in 2025.

We are also proud to have joined the French Tech 2030 program alongside 80 other French innovative companies at a time when cyber resilience has become a strategic priority for Europe.

Today, we protect hundreds of organizations across the world — from large enterprises and government institutions to mid‑sized businesses — and continue to grow through strategic partnerships, innovation, and a commitment to European cybersecurity sovereignty.
