Paris-based startup Filigran is fast becoming the next cybersecurity rocketship to track: The company just raised a $35 million Series B round, only a few months after it raised $16 million in a Series A round.
Filigran’s main product is OpenCTI, an open-source threat intelligence platform that lets companies or public sector organizations import threat data from multiple sources, and enrich that data set with intel from providers such as CrowdStrike, SentinelOne or Sekoia.
The open-source version of OpenCTI has attracted contributions from 4,300 cybersecurity professionals and been downloaded millions of times. The European Commission, the FBI and the New York City Cyber Command all use OpenCTI. The company also offers an enterprise edition that can be used as a software-as-a-service product or hosted on premises, and its clients include Airbus, Marriott, Thales, Hermès, Rivian and Bouygues Telecom.
Filigran has been capitalizing on that success to add other products and build a full-fledged cybersecurity suite dubbed eXtended Threat Management (XTM) suite.
Another product is OpenBAS, a beach and attack simulation platform. You can use OpenCTI and OpenBAS separately, but using them supposedly together provides a better overview of the potential risks.
Filigran is taking advantage of the fact that it’s always easier to launch a second product when your first product is popular. The startup is already working on its third product.
“By 2026, our goal is to offer a comprehensive suite of three complementary products, providing end-to-end solutions in threat management that directly address the complex cybersecurity challenges faced by modern organizations,” co-founder and CEO Samuel Hassine told TechCrunch.
Interestingly, Filigran is also drawing inspiration from GitHub and Hugging Face, the main hubs for open-source software development and artificial intelligence development, respectively. Filigran wants to launch XTM Hub — “a collaborative 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 tradecraft 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 U.S. and Australia, and plans to expand to Germany, Japan and Singapore.
