Filigran Secures $16M to Expand OpenCTI Cybersecurity Threat Suite
Paris-based cybersecurity innovator Filigran has raised €15 million (~$16M) in a Series A funding round led by Accel, with participation from existing investors Moonfire Ventures and Motier Ventures. The investment will fuel the expansion of its open-source threat management platform, OpenCTI, and the development of its broader eXtended Threat Management (XTM) suite.
Why Filigran Stands Out in Cybersecurity
OpenCTI: A Unified Threat Intelligence Platform
Filigran’s flagship product, OpenCTI, is an open-source threat intelligence platform designed to consolidate and contextualize cybersecurity data. Key features include:
- Multi-Source Data Integration: Aggregates threat intelligence from providers like CrowdStrike, SentinelOne, and Sekoia.
- Modular Architecture: Customizable connectors for seamless data enrichment.
- Visualization Tools: Advanced analytics to map threat relationships and patterns.
“OpenCTI provides a holistic view of your threat landscape—from technical vulnerabilities to strategic risks—enhancing detection, incident response, and risk analysis,” explains Samuel Hassine, Filigran’s CEO and co-founder.
OpenBAS: Simulating Real-World Attacks
Filigran’s second product, OpenBAS (formerly OpenEX), is an attack simulation platform that:
- Tests organizational resilience through realistic scenarios (e.g., phishing emails, SMS threats).
- Integrates with OpenCTI for data-driven simulations.
- Tracks performance metrics to improve security postures.
From Side Project to Global Cybersecurity Player
Rapid Growth and Adoption
- OpenCTI boasts 10M+ downloads and 4,000+ GitHub stars.
- 100+ enterprise clients, including Marriott, Thales, Airbus, the FBI, and the European Commission.
- Offers both SaaS and on-premise enterprise solutions.
Future Roadmap: The XTM Suite
Filigran plans to launch two additional products under its XTM Suite, focusing on:
- Data-Driven Risk Analysis
- Crisis Management
“Our vision is a synergistic ecosystem where each product amplifies the others’ value,” says Hassine.
Scaling for Global Impact
- Current team: 40 employees.
- Plans to expand to 70 employees by end of 2024, including a U.S. presence.
Filigran’s trajectory mirrors industry leaders like CrowdStrike and Palo Alto Networks, positioning it as a key disruptor in open-source threat management.
