Thanks to this partnership, cybersecurity teams can now directly access VMRay’s indicators within OpenCTI. Contextualized and immediately actionable, these indicators help save time in investigations and strengthen early attack detection.

Paris, October 13, 2025 – Filigran, the European cybertech company specializing in open-source cybersecurity solutions, and VMRay, the German pioneer in advanced malware and phishing analysis, today announced a strategic partnership. The collaboration will make VMRay’s UniqueSignal feed—renowned for its rich context and high reliability—directly available within OpenCTI.
A Partnership Born from Field Needs
This initiative originated from requests expressed by many joint users of VMRay and OpenCTI. Several large enterprises and government organizations already rely on Filigran’s platform to structure and enrich their threat intelligence feeds.
“This partnership with VMRay illustrates our commitment to providing cybersecurity teams with immediate access to reliable, contextualized intelligence that is ready to be used in their investigations,” said Samuel Hassine, CEO and co-founder of Filigran. “By integrating UniqueSignal into OpenCTI, we make it easier to adopt threat-led cyber defense, benefiting the most exposed companies and government bodies.”
“With UniqueSignal, we want to give cyber teams reliable and directly actionable intelligence,” explained Dr. Carsten Willems, CEO and co-founder of VMRay. “This partnership with Filigran allows them to access it directly within OpenCTI in a simple and immediate way.”
Unique Expertise in Malware Analysis
Founded in 2013 in Bochum, at the heart of Germany’s cybersecurity ecosystem, VMRay has established itself as a leader thanks to its advanced malware analysis technology. Its UniqueSignal feed draws on proprietary sources (spam traps, honeypots, partner networks) and more than ten years of reverse-engineering research.
Each indicator is enriched with detailed information: type of malware, targeted sector, attack methods used, and malicious actors involved. An independent assessment showed that more than 90% of the data provided by VMRay is unique and available earlier than through other sources.
Plug-and-Play Integration with OpenCTI
OpenCTI users can now access VMRay’s UniqueSignal feed without complex setup. Indicators appear directly in their interface, enabling them to:
- Detect emerging threats earlier, including initial attack stages that often lead to ransomware;
- Enrich and correlate investigations with reliable, contextualized data;
- Anticipate malicious campaigns and reduce the risk of costly data breaches.
Benefits and Next Steps
Early feedback from pilot customers highlights both the ease of integration and the complementarity between the UniqueSignal feed and OpenCTI’s graphical knowledge base. Combining VMRay’s behavioral insights with Filigran’s correlation power delivers to cyber teams:
- Significant time savings: direct access to contextualized indicators without technical integration.
- Greater accuracy: over 90% of the data is unique and non-redundant.
- Advanced detection: early identification of infections that could lead to ransomware.
- Enhanced investigations: simplified correlation thanks to OpenCTI’s knowledge graph.
- Faster responses: reduced time to qualify and block threats.
The partnership is already available to joint customers, with a 60-day evaluation period for first adopters. Filigran and VMRay also plan to strengthen community engagement through webinars, conferences, and hands-on training sessions.
