We are Filigran
Best in class
Our company has set itself the sole objective of providing cybersecurity and crisis management teams with the best possible open source software.
We are providing cyber threat intelligence, knowledge subsystems and crisis response solutions to both private and public organizations across the world.
A collaborative approach
Filigran was founded in 2022 in Paris, France, primarily to contribute significantly to this fundamental ecosystem for the security and protection of organizations.
Since the beginning of the journey, we have adopted a proactive approach on collaborative product build, with dedicated committees, user groups and physical events.
Our values
Rooted in open source

We have been engaged in publishing open source projects under free licenses for several years. Providing the best tools to the community is part of our DNA.

The product is king

We focus on the quality of our products and associated source codes by taking the time to review contributions and minimize technical debt.

An open ecosystem

We dedicate energy to maintaining open ecosystems supported by other organizations to ensure constructive feedback on the use and evolution of software.

Teams with high added value

We have chosen to favor small teams with advanced and diversified skills to help our partners and customers to integrate and operationalize our solutions as well as possible.

Committed to the general interest

As our solutions are widely used by administrations, we have built partnerships to help public organizations protect themselves from potential threats and crises.

Innovation and fulfillment

We want to continue to innovate and push new ideas while keeping in mind that professionalism is not incompatible with the fulfillment and fun at work of our teams.

Our vision
We are looking for new Filigran team players in different areas of skills
