*This release is a translated excerpt of a release originally published in France on October 6, 2025.

Filigran, a cybersecurity company headquartered in Paris, France, announced today that it has completed a $58 million Series C funding round. This brings the company's total funding to over $100 million since its inception just three years ago.

The round was led by Eurazeo's Growth team, one of Europe's leading investment groups, with support from Deutsche Telekom (T.Capital). Existing investors Accel and Insight Partners also participated. This funding, following the $35 million Series B round raised a year ago, underscores the growing global demand for Filigran's solutions and its robust revenue growth.

The funds will be used to support and accelerate expansion into new regions, including the Pacific and Middle East, with planned entries into Japan and Saudi Arabia. Filigran will also focus on strengthening its presence in the US and European markets. The company plans to hire new talent from France and Germany to further foster collaboration with its open-source community, which has doubled in size over the past two years.

This funding will also drive the development of OpenGRC, the third module on Filigran's platform. OpenGRC will complement the eXtended Threat Management (XTM) suite, enabling organizations to prioritize cyber risks and focus on the most effective responses. Filigran will also accelerate AI integration, advancing the development of its agentic AI platform, "XTM One." Furthermore, the company will bolster the research and development teams for OpenCTI and OpenAEV (formerly OpenBAS), ensuring the continuous evolution of these existing solutions.

Samuel Hassine, CEO of Filigran, stated: "This Series C is a significant milestone in Filigran's growth journey. We are driven by a clear mission to enable every organization to be more proactive against threats and to leverage intelligence at every level of their security strategy. This funding demonstrates our commitment to realizing that mission: making threat intelligence accessible and actionable for all organizations worldwide."

Raluca Ragab, Partner, and Alexandra Pederzani, Director at Eurazeo Growth, commented: "We are thrilled to see Filigran enabling proactive cyber defense for major companies worldwide. AI is accelerating the scale and sophistication of cyberattacks. Companies need solutions that can transform vast amounts of threat intelligence into actionable insights to prevent future incidents. Filigran's platform delivers exactly that. We are also very excited about the future evolution of its AI capabilities."

Andrei Brasoveanu from Accel added: "One year after we led their Series A, the progress Sam, Julien, and the entire Filigran team have made is remarkable."
