Parisian startup Watermark is poised to become the next cybersecurity rocket to watch: the company just raised a $35 million Series B round, just months after raising $16 million in Series A round.

Filigran’s core product is OpenCTI, an open source threat intelligence platform that allows businesses or public sector organizations to import threat data from multiple sources and enrich that dataset with insights from providers such as CrowdStrike, SentinelOne or Sekoia.

THE open source version by OpenCTI has attracted contributions from 4,300 cybersecurity professionals and has been downloaded millions of times. The European Commission, the FBI and New York City Cyber ​​Command all use OpenCTI. The company also offers an enterprise edition that can be used as software-as-a-service or hosted on-premises, and counts Airbus, Marriott, Thales, Hermès, Rivian and Bouygues Telecom among its customers.

Filigran capitalized on this success to add other products and create a full-fledged cybersecurity suite called the eXtended Threat Management (XTM) suite.

Another product is OpenBAS, a range and attack simulation platform. You can use OpenCTI and OpenBAS separately, but supposedly using them together gives better insight into potential risks.

Filigran takes advantage of 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 comprehensive suite of three complementary products, providing end-to-end threat management solutions that directly address the complex cybersecurity challenges facing modern organizations,” he said. co-founder and CEO Samuel Hassine told TechCrunch.

Interestingly, Filigran also draws inspiration from GitHub and Hugging Face, the leading centers 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 know-how and connect with other members of the Filigran ecosystem,” he added.

Insight Partners is leading the Series B round, with existing investors Accel and Moonfire investing again. In addition to product development, part of this funding round will be used to expand Filigran’s presence in other regions. The company is present in France, the United States and Australia, and plans to expand to Germany, Japan and Singapore.
