Filigran secures $35M with its cybersecurity threat management program

Paris-based startup Filigran is becoming the next cybersecurity rocketship to watch: The company recently raised a $35 million Series B round, just months after it raised $16 million in a Series A round.

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

The open source version of OpenCTI has attracted contributions from 4,300 cybersecurity experts 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 enterprise software that can be used as a software-as-a-service product or hosted on premises, and its customers include Airbus, Marriott, Thales, Hermès, Rivian and Bouygues Telecom.

Filigran has been using that success to add other products and create a full cybersecurity suite called the eXtended Threat Management (XTM) suite.

Another product is OpenBAS, an ocean environment and attack simulation platform. You can use OpenCTI and OpenBAS separately, but using them together gives a better idea of ​​potential risks.

Filigran uses the fact that it is 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 complete portfolio of three complementary products, providing end-to-end threat management solutions that directly address the complex cybersecurity challenges facing modern organizations,” founder and CEO Samuel Hassine told TechCrunch.

Interestingly, Filigran also draws inspiration from GitHub and Hugging Face, the main sites for open source software development and artificial intelligence development, respectively. Filigran wants to launch the 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 platform where users can access resources, share trades and connect with others in the Filigran ecosystem,” he added.

Insight Partners is leading the Series B round, with existing investors Accel and Moonfire also investing. 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.
