About Filigran

Filigran is a cybersecurity company founded in September 2022 by CEO Samuel Hassine and CTO Julien Richard. Hassine has over 15 years of experience in cyber threat intelligence and crisis management, including a role as the head of Threat and Risk Analysis at the French National Cybersecurity Agency (ANSSI). Richard brings two decades of experience in managing product and engineering teams in the data and AI sectors.

The company's core offering is its eXtended Threat Management (XTM) suite, which aims to provide a proactive and unified approach to cybersecurity. This suite is built on open-source principles and includes several key products. OpenCTI is a threat intelligence platform that helps organizations consolidate, organize, and visualize cyber threat knowledge. OpenAEV (formerly OpenBAS) is a breach and attack simulation platform for testing security controls and resilience against real-world attack scenarios. The company is also developing OpenGRC, a tool for threat-informed cyber risk management.

Filigran operates on a business model that combines open-source community editions with enterprise-level services. The company generates revenue by offering enterprise editions of its software, which include advanced features, as well as managed cloud hosting, technical support, training, and consulting services. This approach has attracted a wide range of clients, from public sector bodies like the FBI and the European Commission to major corporations such as Airbus, Marriott, and Rivian.

Since its inception, Filigran has experienced rapid growth, marked by several successful funding rounds, including a €5 million Seed round in June 2023, a $35 million Series B in October 2024, and a $58 million Series C in October 2025. The company is using this capital to expand its global presence, with plans to grow its teams in the U.S. and establish new offices in regions like Saudi Arabia and Japan, while also investing in product development, particularly in its agentic AI capabilities designed to automate threat analysis.
