Paris-based startup Filigran is fast becoming the next cybersecurity rocketship to track. The company has just raised a $35 million Series B round, only a few months after it raised $16 million in a Series A round.
Filigran’s main 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 data set with intel from providers such as CrowdStrike, SentinelOne, or Sekoia. The open-source version of OpenCTI has attracted contributions from 4,300 cybersecurity professionals and 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, and its clients include Airbus, Marriott, Thales, Hermès, Rivian, and Bouygues Telecom.
Filigran has been capitalizing on the success of OpenCTI to add other products and build a full-fledged cybersecurity suite dubbed eXtended Threat Management (XTM) suite. Another product is OpenBAS, a breach and attack simulation platform. The startup is also working on its third product and plans to offer a comprehensive suite of three complementary products by 2026, providing end-to-end solutions in threat management that directly address the complex cybersecurity challenges faced by modern organizations.
Interestingly, Filigran is drawing inspiration from GitHub and Hugging Face, the main hubs for open-source software development and artificial intelligence development, respectively. The company plans to launch XTM Hub, “a collaborative platform designed to empower the cybersecurity community,” by the end of the year.
Insight Partners is leading the Series B round, with existing investors Accel and Moonfire investing once again. In addition to product development, a portion of this funding round will be used to expand Filigran’s presence in other regions, including Germany, Japan, and Singapore.
