Threat intelligence is more important now than ever before due to AI threats. However, it has challenges such as the ability to afford, absorb, contextualise and incorporate data in real-time. French cybersecurity startup Filigran helps enterprises unlock threat intelligence and fully realise its benefits, enabling them to better prioritise alerts, investigate threats and optimise their existing cybersecurity stack.
Now, Filigran has secured $58 million in Series C funding, bringing its total capital raised to over $100 million. This includes the €15 million Series A funding raised last year and the €5 million investment raised in 2023.
The latest round was led by Eurazeo, with participation from Deutsche Telekom and existing investors Accel and Insight Partners.
With the latest funding, Filigran is preparing to expand its product suite and global footprint. A major focus is OpenGRC, a new platform designed to help organisations prioritise cyber risks and take the most effective preventive actions. This addition aims to bridge the gap between detection and decision-making, ensuring that businesses can manage security risks strategically, not just technically.
Filigran also plans to build a specialised agent platform to enhance its real-time capabilities and deepen integration across its ecosystem of tools. On the expansion front, the company will strengthen its presence in the US and Europe while entering the Pacific and Middle East markets, a move that signals its ambition to become a global cybersecurity leader.
Next-gen open-source threat management
Founded in 2022 by Samuel Hassine and Julien Richard, Filigran works with the mission to develop innovative open-source solutions, designed specifically to address the complex challenges organisations face in anticipating cyber risks and threats.
Samuel has more than 15 years of experience in cyber threat intelligence and risk management, including with the French National Agency for the Security of Information Systems (ANSSI). Julien has more than 20 years of experience leading product and engineering teams while designing complex software in big data and AI.
The company is building a next-generation open-source threat intelligence management platform. This platform reduces the barriers to threat intelligence adoption and harnesses the open source community to create a network of enterprises, governments, and researchers who contribute to threat intelligence and other cyber data.
Filigran has achieved rapid adoption among high-profile clients, including the FBI and the European Commission. More than 6,000 organisations now rely on its tools to safeguard sensitive data and operations. This level of trust speaks volumes about the company’s reliability and innovation in a field where precision and speed are crucial.
Building the future of cyber intelligence
At the core of Filigran’s technology lies a commitment to open-source collaboration and real-time intelligence. Its flagship platform, OpenCTI, has become a trusted tool for security teams worldwide. By aggregating and analysing data from multiple sources, including major threat intelligence providers like CrowdStrike, OpenCTI helps organisations detect, understand, and respond to threats faster. The platform’s popularity is evident from its millions of downloads and widespread use among both public and private institutions.
Complementing OpenCTI is OpenBAS, a simulation platform that replicates real-world cyberattacks to test an organisation’s resilience. This proactive approach allows cybersecurity teams to assess vulnerabilities before attackers exploit them. Together, these tools reflect Filigran’s strategy of empowering organisations to stay ahead of evolving threats rather than reacting after breaches occur.
Samuel Hassine, CEO of Filigran, said: “This Series C round is an important milestone in Filigran’s journey. We are extremely proud of the collective commitment that brought us here, with one clear mission: enabling organisations everywhere to be more proactive against threats and to leverage intelligence at every level of their security strategy. It reflects everyone’s commitment to achieving our mission, which is to make threat intelligence accessible and actionable for all organisations worldwide.”
