The French cybersecurity company Filigran announced a Series C funding round of $58 million, bringing its total funding since its inception in 2022 to more than $100 million. The new round was led by Eurazeo, with participation from Deutsche Telekom (T.Capital) and longtime investors Accel and Insight Partners.
A year after a $35 million Series B, this round underscores Filigran’s strong commercial momentum and sustained revenue growth, driven by rising demand for its solutions across the globe.
The financing is aimed at supporting Filigran’s growth and accelerating its international expansion. The company plans to establish a presence in new regions, notably Asia-Pacific (with a footprint in Japan) and the Middle East (in Saudi Arabia).
International expansion and strengthening of the teams
Filigran also intends to bolster its American and European markets, particularly in France and Germany, by onboarding new talent and increasing engagement with the open-source community, which has doubled in two years.
This funding also backs the development of OpenGRC, the third module of Filigran’s eXtended Threat Management (XTM) suite. This new tool will enable organizations to prioritize cyber risks and act first on the most critical ones.
The company furthermore plans to accelerate the integration of artificial intelligence through the creation of XTM One, an AI agents platform, and to strengthen its R&D teams on OpenCTI (threat intelligence) and OpenBAS (security simulation and validation).
“This Series C round marks an important milestone in Filigran’s journey,” said Samuel Hassine, CEO and co-founder. “Our mission remains clear: to empower all organizations to be more proactive against threats and to make threat intelligence accessible and actionable worldwide.”
Founded in 2022 by Samuel Hassine and Julien Richard, Filigran develops open-source solutions that help organizations anticipate cyber threats. Its XTM suite brings together OpenCTI, which structures and operationalizes threat intelligence, and OpenBAS, which simulates attacks to identify security gaps in real time.
Filigran’s solutions are currently used by major international companies such as Marriott, Rivian, and Bouygues Telecom, as well as by public bodies including the European Commission, the FBI, several U.S. and Australian federal agencies, and various European institutions.
