About poisettx
We believe every organization deserves access to professional-grade cybersecurity exercises — regardless of budget or team size.
Why we built poisettx
The European NIS2 directive is changing the landscape for cybersecurity readiness. A growing number of organizations are now required to structurally invest in incident response training — including tabletop exercises.
Yet for most organizations, conducting a tabletop exercise remains a time-consuming, expensive, and logistically complex process. Scripts take weeks to write, key roles are unavailable, and external consultants charge tens of thousands of euros for generic scenarios that don't reflect the organization's actual context.
We built poisettx to change this. By combining AI with a purpose-built digital environment, we make it possible for any organization to generate, execute, and evaluate realistic tabletop exercises — in minutes instead of months, at a fraction of the cost.
Our principles
Security-First
We handle sensitive organizational data with the highest standards. Encryption, access control, and data isolation are foundational — not afterthoughts.
AI with Human Oversight
AI generates and assists, humans review and decide. Every generated script, document, and report can be reviewed and adjusted before use.
Accessible by Design
Professional-grade cybersecurity exercises shouldn't require a consultant and a six-figure budget. We're democratizing what was previously only available to enterprises.
Built in Europe
Designed with European compliance requirements in mind from day one. GDPR-compliant, NIS2-aligned, and hosted on European infrastructure.

Michiel started his career in cybersecurity at Fox-IT, delivering security services to organizations in high-risk threat environments, before moving to KPN to shape enterprise cybersecurity product offerings. He later co-founded and exited one of the first Dutch digital-asset investment firms. At poisettx, he leads product strategy and go-to-market, drawing on his security background and years of operating through high-stakes situations to build a platform that reflects what incident readiness looks like in practice.

Floris Hol
Co-founder, Product & Technology
Floris started his career in AI a decade ago, spending seven years on Deloitte's AI team where he finished as lead AI engineer, shipping large-scale AI systems into highly regulated enterprises. His consulting background gave him a sharp eye for how technology lands inside real organizations and where it actually creates value. He went on to found and raise funding for a separate venture before founding poisettx, where he leads product and technology — building AI that gives organizations the edge they need in a world where threats don't wait.
