OpenCTI maker Filigran raises $16M for its cybersecurity threat management suite

Paris-based Filigran raised €15 million led by Accel to grow its open source threat management suite built around OpenCTI, a threat intelligence platform that consolidates and contextualizes data via connectors, and OpenBAS, an attack simulation tool. With more than 100 paying customers (including major enterprises and government agencies) and strong open source adoption, Filigran plans to expand its portfolio to four interoperable products for threat intelligence, simulation, risk analysis, and crisis management, growing its team to about 70 employees and establishing a U.S. presence.
