October 7, 2025

Filigran, a cybersecurity company specialising in AI-driven threat intelligence and risk management, has raised $58m in Series C funding.

The round was led by Eurazeo, Insight Partners, Accel, and Deutsche Telekom’s T.Capital, marking another major milestone in Filigran’s rapid growth since launching three years ago.

Filigran plans to use the funds to accelerate product development, expand its research and engineering teams, and scale globally. The company will open new offices in Saudi Arabia and Japan, triple its U.S. headcount, and strengthen its presence in the DACH region.

The funding will also drive the development of OpenGRC, an open-source cyber risk management platform, and XTM One, its agentic AI system designed to automate threat analysis and enhance decision-making for security teams.
