Custom CTFs for your teams
A CTF ("Capture The Flag") is an open-source investigation exercise in the form of a game: your staff solve, alone or in teams, a series of challenges drawn from real cases. A lively way to build skills, raise awareness and bring people together.
How it works
Rather than a top-down course, your teams investigate. Each challenge is solved by applying the right OSINT reflexes — searching, cross-checking, verifying — on a dedicated platform where progress is tracked in real time. The pull of the game embeds learning far more durably than a classic lecture.
What it's for
Train
Build your teams' open-source investigation skills through hands-on practice.
Raise awareness
Show concretely how large a footprint an organisation and its staff leave online.
Bring together
A team format ideal for a seminar, a corporate event, or strengthening cohesion.
Assess
Spot and gauge the abilities of staff or candidates in realistic conditions.

Proven expertise
Since 2020 I have co-organised the Challenge OSINT 317, an annual competition for French government services, including several editions at the InCyber Forum. The custom CTFs draw on a platform I have built and refined over these editions.
