Paris-based startup Filigran is rapidly growing into the next cybersecurity rocketship. The company raised a $35 million Series B round just months after raising $16 million in a Series A round.
Filigran’s main product is OpenCTI, an open source threat intelligence platform that allows enterprises or public sector organizations to pull threat data from multiple sources and enrich those datasets with information from providers such as CrowdStrike, SentinelOne or Sekoia.
The open source version of OpenCTI has received contributions from 4,300 cybersecurity experts and has been downloaded millions of times. The European Commission, FBI, New York City Cyber Command, and others all use OpenCTI. The company also offers an enterprise edition that can be used as a Software-as-a-Service (SaaS) offering or hosted on-premises, and its customers include Airbus, Marriott, Thales, Hermès, Rivian, and Bouygues Telecom.
Filigran has been leveraging this success to add other products and build a full-fledged cybersecurity suite called its eXtended Threat Management (XTM) suite.
Another product is OpenBAS, a beach and attack simulation platform. Although OpenCTI and OpenBAS can be used separately, using them together can provide a better overview of potential risks.
Filigran is taking advantage of the fact that it is always easier to launch a second product when the first one becomes popular. The startup is already developing its third product.
“By 2026, our goal is to deliver a comprehensive suite of three complementary products, an end-to-end solution in threat management that directly addresses the complex cybersecurity challenges facing modern organizations,” co-founder and CEO Samuel Hassine told TechCrunch. “It’s about providing .”
Interestingly, Filigran also took inspiration from GitHub and Hugging Face, major hubs for open source software development and artificial intelligence development. Filigran hopes to launch XTM Hub, a “collaboration platform designed to empower the cybersecurity community,” by the end of the year, Hassine said.
“The hub will serve as a central forum where users can access resources, share crafts and connect with others in the Filigran ecosystem,” he added.
Insight Partners is leading the Series B round, with existing investors Accel and Moonfire investing once again. In addition to product development, a portion of this funding round will be used to expand Filigran’s presence in other regions. The company operates in France, the United States and Australia, and plans to expand to Germany, Japan and Singapore.
