Paris-based cybertech Filigran has completed a Series C funding round worth US$58 million, bringing its total funding to over US$100 million in three years.
The round was led by Eurazeo’s Growth team, part of the European investment group Eurazeo, with participation from Deutsche Telekom’s investment arm T.Capital and existing investors Accel and Insight Partners.
Following its previous US$35 million round a year ago, the new funding reflects growing global demand for Filigran’s solutions and continued revenue growth.
The company plans to use the capital to expand into new regions, including the Pacific and the Middle East, with particular focus on Japan and Saudi Arabia.
It will also strengthen its presence in the US and Europe by hiring new talent in France and Germany and enhancing collaboration with its open-source community, which has doubled in size over the past two years.
The funds will support the development of OpenGRC, a third module for Filigran’s platform designed to complement its eXtended Threat Management (XTM) suite.
The company will also advance its use of AI through the creation of an AI Agent platform, XTM One, and increase R&D efforts across its existing OpenCTI and OpenBAS solutions.

“This Series C round is an important milestone in Filigran’s journey,”
said Samuel Hassine, CEO of Filigran.
“It reflects our commitment to enabling organisations to be more proactive against threats and to leverage intelligence at every level of their security strategy.”
Founded in 2022 by Samuel Hassine and Julien Richard, Filigran’s XTM suite combines OpenCTI, which structures and operationalises global threat intelligence, and OpenBAS, a security validation platform that identifies vulnerabilities using real-time threat data.
Filigran’s solutions are used by companies including Rivian and Bouygues Telecom, as well as public sector organisations such as the European Commission, the FBI, and several US, Australian, and European government agencies.
