Filigran raises $35 million for its ceybersecurity threat management package

Startup based in Paris Filigree is quickly becoming the next cybersecurity rocket ship to follow: the company just raised a $35 million Series B round just a few months after $16 million in a Series A round.

Filigran’s flagship product is OpenCTI, an open-source threat intelligence platform that allows companies or public sector organizations to import threat data from multiple sources and enrich that dataset with information from providers like CrowdStrike, SentinelOne or Sekoia.

The open source version from OpenCTI has received contributions from 4,300 cybersecurity professionals and has 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. Customers include Airbus, Marriott, Thales, Hermès, Rivian and Bouygues Telecom.

Filigran has taken advantage of that success to add other products and build a full-fledged cybersecurity suite called the 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 will give you a better overview of the potential risks.

Filigran takes advantage of the fact that it is always easier to launch a second product if 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 threat management solutions that directly address the complex cybersecurity challenges facing modern organizations,” shared co-founder and CEO Samuel Hassine told TechCrunch.

Interestingly, Filigran also draws inspiration from GitHub and Hugging Face, the main hubs for open-source software development and artificial intelligence, respectively. Filigran aims to launch XTM Hub – “a collaboration platform designed to strengthen 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 reinvesting. In addition to product development, part of this funding round will be used to expand Filigran’s presence in other regions. The company operates in France, the US and Australia and plans to expand to Germany, Japan and Singapore.
