Cyber threats no longer knock politely at the door. They move fast, evolve faster, and exploit every weakness with precision. Organizations across the world now face a reality where waiting for an attack is no longer an option—anticipation, intelligence, and preparedness are the only real defenses. It is within this demanding and ever-shifting landscape that Filigran has emerged as a force reshaping how cybersecurity is built, shared, and strengthened.

Founded with a bold vision to make cybersecurity more open, collaborative, and actionable, Filigran is not just another technology company. It is a mission-driven organization built on the belief that security is strongest when knowledge is shared and when tools are created for the collective good. In a short span of time, the company has grown into a global open-source cybersecurity powerhouse, and is trusted by thousands of organizations that rely on its platforms to understand threats, test defenses, and respond with confidence.

A Company Built on Purpose and Open Values

Filigran was created in September 2022 with a single, clear objective: to equip cybersecurity and crisis management teams with the most powerful, practical, and accessible tools driven by real-world threat intelligence. From welcoming its first employee and customer to rapidly scaling across continents, the company’s journey has been defined by speed, focus, and a deep commitment to the public interest.

Within months of its founding, Filigran had grown into a strong engineering-focused team. By 2023, it had secured significant investment to accelerate development and expand its capabilities. As adoption surged, so did the company’s workforce, crossing 50 employees in 2024 and surpassing 100 people globally by 2025. Today, Filigran supports users across EMEA, North America, and the Asia-Pacific region, delivering round-the-clock expertise and service.

What truly sets Filigran apart is not just its rapid growth, but the values guiding it. The company remains deeply rooted in open source, believing that transparency and community collaboration produce stronger, more trustworthy security technologies. Small, highly skilled teams drive innovation, while a relentless focus on product quality ensures that every line of code serves a purpose. Filigran also actively supports public institutions and critical infrastructure providers, reinforcing its commitment to the broader good beyond commercial success.

Powering Modern Security with the XTM Suite

At the heart of Filigran’s technology ecosystem lies its open-source Extended Threat Management (XTM) suite, designed to help organizations understand their threat environment, anticipate attacks, validate defenses, and respond decisively. The suite brings together advanced threat intelligence management and real-world attack simulation into one unified security approach.

The first cornerstone of this ecosystem is OpenCTI, Filigran’s cyber threat intelligence platform. OpenCTI transforms raw threat data into structured, actionable intelligence that security teams can actually use. By collecting, correlating, and visualizing threat information from hundreds of global sources, OpenCTI enables organizations to see the bigger picture behind attacks—actors, techniques, malware, and indicators—within a single, intuitive interface.

With advanced automation and artificial intelligence embedded into its workflows, OpenCTI dramatically accelerates the entire intelligence lifecycle. Threat detection and response become faster, false positives drop significantly, and analysts spend less time chasing noise and more time making strategic decisions. Real-time sharing, role-based access, and centralized case management turn intelligence into coordinated action across teams and tools.

The platform’s flexibility allows it to adapt easily to varied use cases such as threat monitoring, hunting, investigations, and disinformation analysis. Through AI-powered search, summaries, and report generation, OpenCTI simplifies even the most complex intelligence tasks, empowering both seasoned analysts and smaller security teams to operate at a higher level.

Turning Intelligence into Action with Exposure Validation

Understanding threats is only part of the equation. Proving that defenses can withstand those threats is just as critical. This is where Filigran’s second major platform, OpenAEV, redefines how organizations validate their security posture.

OpenAEV is the industry’s first open-source, threat-informed adversarial exposure validation platform. It allows organizations to simulate real-life cyberattacks based on prioritized intelligence, testing not just tools, but processes and people as well. By emulating the most probable attack paths using globally recognized frameworks, security teams can identify weak points before attackers do.

What once took weeks of planning can now be achieved in a fraction of the time. OpenAEV reduces crisis simulation planning dramatically, while enabling organizations to scale their simulation programs with measurable growth. Its AI-driven remediation guidance helps teams move from detection to resolution faster, offering practical, prioritized actions rather than generic vulnerability alerts.

Because OpenAEV works with existing security tools and does not require additional endpoint agents, it fits seamlessly into resource-constrained environments. Organizations can run recurring simulations across multiple threat vectors—from phishing and ransomware to lateral movement and network infiltration—while tracking performance improvements over time through data-driven reporting.

Most importantly, OpenAEV brings continuous improvement into daily security operations. It enables proactive defense, strengthens team response, and ensures that security strategies evolve as rapidly as the threats they face.

A Human Vision for a Safer Digital World

Despite its advanced technology, Filigran’s story remains deeply human. It is a company built by engineers, researchers, and security experts who believe that innovation must serve people first. Its culture promotes fulfillment and creativity alongside professionalism. Its partnerships with public organizations protect communities, not just corporations. And its open ecosystems ensure that users are not just customers, but contributors to a shared mission of resilience.

In a world where cyber risks grow more complex by the day, Filigran stands as a reminder that the strongest defenses are built not in isolation, but through collaboration, intelligence, and trust. By making powerful cybersecurity tools accessible, adaptable, and open, Filigran is not only helping organizations defend themselves—it is reshaping the very way digital security is understood and practiced worldwide.

As the digital battlefield becomes more unpredictable, Filigran’s open, intelligence-driven approach offers something rare in today’s security landscape: clarity, preparedness, and confidence for the future.
