European CyberTech Filigran raises €15M in series A funding, set to expand to the United States and Australia

Filigran has quickly secured more than 4,200 customers globally, including Marriott, Hermès, Airbus, Novartis, the FBI and the European Commission. The investment will be used to expand internationally, further develop its open-source “eXtended Threat Management” suite, and grow its team. This round comes just six months after a €5M seed round.

European cybertech Filigran announces a €15M Series A fundraising led by global venture capital firm Accel, just six months after its initial €5M seed round. Existing investors Moonfire Ventures and Motier Ventures also participated in the round. Filigran, founded in France in October 2022 by Samuel Hassine and Julien Richard, is building a next generation open source threat intelligence management platform. It is already being used by more than 4,200 organisations worldwide.

Threat intelligence is now more important than ever due to AI threats and faster exploitations. However, it has historically been constrained by customers’ ability to afford, absorb, contextualise and incorporate data in real-time. It is due for a refresh.

Filigran helps enterprises unlock threat intelligence and fully realise its benefits, enabling them to better prioritise alerts, investigate threats and optimise their existing cybersecurity stack. Thanks to its open source and easy-to-use offering, Filigran is reducing the barriers to threat intelligence adoption and harnessing the open source community to create a network of enterprises, governments and researchers who contribute to threat intelligence and other cyber data.

Filigran will use the funding to accelerate its global expansion and product development in three key areas:

  1. Filigran will open offices in the United States and Australia in 2024 with a focus on securing new strategic partnerships, accelerating adoption of Filigran’s solutions by organisations in North America and Asia-Pacific, and providing local customer support.
  2. Filigran will continue to grow its XTM portfolio with:
    • OpenCTI: A threat intelligence platform designed to help cybersecurity teams organise, store and operationalise  threat intelligence information at a technical, operational and strategic level.
    • OpenBAS: An attack simulation platform that uses OpenCTI’s Threat intelligence to create attack simulations, stress tests, and threat management exercises. OpenBAS establishes a consolidated view of potential gaps in a company’s cyber security response. 
    • A new XTM solution which will be released in 2024. 
  3. Filigran will develop its Big Data and Artificial Intelligence teams, recruiting new talent and enriching its XTM solutions.

“In a difficult environment for tech fundraising, completing two significant rounds of financing in less than a year demonstrates Filgran’s ability to develop and execute a strong platform for anticipating and analysing cyber threats,” said Filigran CEO Samuel Hassine. “This Series A will enable us to accelerate the development of our XTM portfolio and accelerate the business. With a strong international focus and an open-source vision of the future of cybertech, we have the resources to achieve our mission more quickly.”

“The Filigran team has achieved a huge amount since launch and we believe that their open source community and platform approach will enable organisations to upscale their threat intelligence efforts,” said Andrei Brasoveanu, Partner at Accel. “With Sam and Julien’s deep sector expertise and a large number of government and enterprise customers already using Filigran, there’s a significant global opportunity ahead for the company and we look forward to joining their journey!”

Filigran’s clients include global companies such as Marriott, Thales, Hermès, Airbus, Novartis, Bouygues Telecom as well as public sector entities including the NYC Cyber ​​Command, the FBI, the European Commission, ENISA, and the Dutch police. Filigran has built a strong ecosystem of partners including Deloitte, Orange Cyberdefense, Deepwatch, Arctic Wolf, Atos, Wavestone and Intrinsec. 

Founded in October 2022, Filigran currently has 40 employees, with plans to grow the team to 70 by the end of 2024. It was co-founded by Samuel Hassine (CEO) and Julien Richard (CTO). Samuel has more than 15 years’ experience in cyber threat intelligence and risk management, including with the French National Agency for the Security of Information Systems (ANSSI), where he managed and planned national cyber defence exercises before heading the Threat and Risk Analysis team. Julien Richard has more than 20 years’ experience leading product and engineering teams while designing complex software in big data and AI.
