Filigran secures $35 million for its cybersecurity threat management suite.

The Paris-based startup Filigran is gaining relevance in the cybersecurity sector after securing a $35 million Series B funding round, just a few months after raising $16 million in a Series A round. Its main product, OpenCTI, is an open-source threat intelligence platform that allows businesses and public sector organizations to import threat information from various sources, as well as enrich this data with information from providers like CrowdStrike, SentinelOne, and Sekoia.

The open-source version of OpenCTI has been adopted by 4,300 cybersecurity professionals and has been downloaded millions of times. Among its users are the European Commission, the FBI, and the Cyber Command of New York City. Additionally, the company offers an enterprise edition that can be used as a cloud service or hosted on the client's premises, with clients including giants such as Airbus, Marriott, Thales, Hermès, Rivian, and Bouygues Telecom.

Thanks to its success with OpenCTI, Filigran has begun developing other products and has created a cybersecurity suite known as eXtended Threat Management (XTM). Another of its developments is OpenBAS, a platform for attack simulations and penetration testing. While OpenCTI and OpenBAS can be used independently, their combined use is recommended to provide a better overview of potential risks.

The startup is already working on its third product, and according to its co-founder and CEO, Samuel Hassine, the goal is to offer a complete suite of three complementary products by 2026, addressing the complex cybersecurity challenges faced by modern organizations. Additionally, Filigran seeks inspiration from platforms like GitHub and Hugging Face, leaders in the development of open-source software and artificial intelligence, respectively. By the end of the year, they plan to launch XTM Hub, a collaborative platform intended to boost the cybersecurity community.

Insight Partners is leading the Series B funding round, with participation from existing investors such as Accel and Moonfire. Part of the funds raised will be allocated to product development and expanding Filigran's presence in new regions, as it currently operates in France, the United States, and Australia, with plans to expand to Germany, Japan, and Singapore.
