? The Company

Founded in 2022, Filigran is a global cybersecurity company on a mission to empower defense teams to be proactive through open-source solutions that uncover threats and drive action.

Filigran stands out in the cybersecurity ecosystem through its open-source, AI-powered and threat-informed approach to Continuous Threat Exposure Management (CTEM). Our eXtended Threat Management (XTM) platform brings together threat intelligence, exposure validation and cyber risk reduction, enabling organizations to better understand their threat landscape and take action.

At the heart of Filigran is our open-source approach. Our vision is to unite defenders into a integral community to make security more open, resilient and collaborative.

As Filigran continues to scale globally, we are building the organization, infrastructure and capabilities needed for our next stage of growth. How we scale matters just as much as how fast we scale: our CORE values: Cohesion, Openness, Responsibility and Equity shape how we work together, make decisions and build for the future.
