Filigran Raises €32.3 Million for Its Cybersecurity Platforms

On October 28, 2024, the French startup Filigran, specializing in open-source cybersecurity platforms, announced a €32.3 million Series B funding round. The round was led by U.S. investment firm Insight Partners, with participation from existing investors, including Accel and Moonfire. This comes just eight months after a previous funding round of €15 million.

Filigran markets two platforms. The first, OpenCTI, aggregates and analyzes cyber threat data specific to a company, with a claimed 6,000 open-source contributors. The second, OpenBAS, recently launched, simulates attack scenarios and conducts stress tests to validate a company’s security posture. Filigran has integrated these platforms into a software suite called eXtended Threat Management (XTM).

The French startup counts several high-profile clients, including the FBI, the European Commission, various federal agencies and European ministries, as well as major corporations like Airbus. The previous funding round enabled Filigran to open two international offices: one in Australia, dedicated to the Asia-Pacific region, and another in the United States, the core of its growth.

“Nearly 75% of cybersecurity spending is in the United States, making it a highly prioritized market,” noted Samuel Hassine, CEO of Filigran and former head of threat analysis at ANSSI, in an interview with L’Usine Digitale.

This new funding round will allow Filigran to further accelerate its international expansion and the development of new products. The startup plans to launch a third platform in 2025 focused on risk analysis and expects to hire around sixty new employees by the end of 2025. Filigran currently has 82 employees.
