Paris-based startup Filigran has recently secured a significant amount of funding, raising $35 million in a Series B round. This comes on the heels of a $16 million Series A round that the company raised just a few months prior. Filigran’s key product, OpenCTI, is an open-source threat intelligence platform that allows organizations to import threat data from various sources and enhance that data with information from providers such as CrowdStrike, SentinelOne, and Sekoia.
The open-source version of OpenCTI has garnered contributions from over 4,300 cybersecurity professionals and has been downloaded millions of times. Notable users of OpenCTI include the European Commission, the FBI, and the New York City Cyber Command. Additionally, Filigran offers an enterprise edition of OpenCTI that can be used as a software-as-a-service product or hosted on premises. Clients of this enterprise edition include prominent companies such as Airbus, Marriott, Thales, Hermès, Rivian, and Bouygues Telecom.
Building upon the success of OpenCTI, Filigran has expanded its product offerings to create a comprehensive cybersecurity suite called the eXtended Threat Management (XTM) suite. One of the products within this suite is OpenBAS, a breach and attack simulation platform. While OpenCTI and OpenBAS can be utilized independently, using them together reportedly provides a more comprehensive view of potential risks.
Filigran’s ability to launch additional products is facilitated by the popularity of its existing offerings. The company is already developing its third product, with plans to offer a suite of three complementary products by 2026. CEO Samuel Hassine envisions these products providing end-to-end solutions for threat management to address the complex cybersecurity challenges faced by modern organizations.
In a unique move, Filigran is drawing inspiration from platforms like GitHub and Hugging Face to create XTM Hub, a collaborative platform aimed at empowering the cybersecurity community. This hub, set to launch by the end of the year, will serve as a central forum where users can access resources, share knowledge, and connect with others in the Filigran ecosystem.
Leading the Series B funding round is Insight Partners, with existing investors Accel and Moonfire also participating. In addition to further product development, a portion of the funding will be allocated towards expanding Filigran’s presence in other regions. While the company currently operates in France, the U.S., and Australia, there are plans to expand into Germany, Japan, and Singapore in the near future.
