About GRC Factory

Two Services.
Total Focus.

We are an audit specialist consultancy. We focus exclusively on audit readiness and internal audits — and we are very good at both.

Our Story

Specialists,
Not Generalists

GRC Factory was founded on one belief: organisations deserve an audit partner who has done this hundreds of times — with a standardised methodology and consistent, reliable results.

We do two things: audit readiness and internal audits. Every tool, template, and process we have built is aimed at those two services. Our 13-process internal audit framework reflects years of refinement across more than 150 client engagements.

Based in Rotterdam, we work with organisations across finance, healthcare, technology, and logistics throughout the Netherlands.

What We Stand For

🎯
Focused
Two services. Every tool, template, and process we have built is aimed at audit readiness and internal audits — nothing else.
📐

Accurate, evidenced, audit-defensible work. We never pad reports to appear thorough. Every finding is supported by specific evidence.
🤝
Partnered

🔁
Consistent
Standardised methodology. Every client receives the same quality, the same structure, and the same standard of evidence.
