Paris-based startup Filigran is quickly emerging as the next cybersecurity rocket. The company just raised a $35 million Series B round, just months after raising $16 million in a Series A round.
Filigran's main product is OpenCTI. OpenCTI is an open-source threat intelligence platform that allows enterprises and public sector organizations to import threat data from multiple sources and enrich that data set with intelligence from providers such as CrowdStrike, SentinelOne, and Sekoia.
The open source version of OpenCTI has attracted contributions from 4,300 cybersecurity professionals and has been downloaded millions of times. The European Commission, FBI, and 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 customers include Airbus, Marriott, Thales, Hermès, Rivian, Bouygues Telecom, and more. .
Filigran is leveraging its 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. Although you can use OpenCTI and OpenBAS separately, using them together probably provides a better overview of potential risks.
Filigran takes advantage of the fact that it is always easier to launch a second product once the first one is popular. The startup is already working on its third product.
“By 2026, our goal is to provide a comprehensive suite of three complementary products to provide end-to-end threat management that directly addresses the complex cybersecurity challenges faced by modern organizations. ,” co-founder and CEO Samuel Hassin told TechCrunch.
Interestingly, Filigran also draws inspiration from GitHub and Hugging Face, leading hubs for open source software development and artificial intelligence development, respectively. Hassin said Filigran hopes to launch XTM Hub, a “collaborative platform designed to empower the cybersecurity community,” by the end of the year.
“This hub will serve as a central forum where users can access resources, share their tradecraft, and connect with other users within 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, a portion of this funding round will be used to expand Filigran's presence in other regions. The company has operations in France, the US and Australia, with plans to expand to Germany, Japan and Singapore.
