French cybersecurity startup Filigran SAS today revealed that it has raised $58 million in new funding to accelerate global expansion and continue developing its artificial intelligence-driven threat-management platform.
Founded in 2022, Filigran offers open-source and enterprise cybersecurity solutions under its eXtended Threat Management vision. The company aims to democratize access to threat intelligence and to build interoperable, community-driven tools that support better decision making and proactive defense across organizations.
Filigran’s main offering, called OpenCTI, is a threat intelligence platform that ingests, structures, correlates and enriches data from multiple sources such as commercial feeds, internal telemetry and open-source intelligence, to provide a unified view of threats. OpenCTI’s offers a flexible data model and connector architecture that allows for integration with various security tools and its open nature encourages community contributions for analytics, detection logic and connectors.
The company also offers OpenBAS, for Breach and Attack Simulation, a service that allows organizations to simulate realistic attack scenarios based on threat intelligence inputs to test their controls and resilience. Organizations can validate configurations, assess gaps and prioritize mitigation efforts proactively using the service.
Filigran also delivers a suite of services for enterprise adoption, including managed cloud hosting, technical support, consulting, integration services, training and custom development to help organizations operationalize its platforms in production environments.
More recently, Filigran is building OpenGRC, an open-source platform for threat informed cyber risk management. OpenGRC is said by the company to transform traditional, static compliance practices into dynamic metrics and actionable alerts, enabling chief information security officers and risk managers to improve risk assessment process metrics and reporting, also leading to an informed investment decision-making.
The Series C funding round was supported by Eurazeo SE, Insight Partners LP, Accel Partners LP and Deutsche Telekom AG (T.Capital). Filigran previously raised a Series B funding round of $35 million in October 2024.
