Cybersecurity governance for Belgian SMEs

Real security.

Not compliance theater.

CySLok helps Belgian and European SMEs turn ISO27001, CyFun 2025 and NIS2 into security that people understand, apply and sustain.

Tom De Cubber

Founder & Virtual CISO

I help organizations build security that works in practice, not just on paper.

Many SMEs invest in ISO27001, CyFun or NIS2 preparation and end up with policies that look good but are rarely used. That creates the illusion of control, without improving day-to-day security.

My approach is different. I translate requirements into governance, processes and controls that are clear, proportionate and usable by the people who actually need them.

The result is a security program that supports certification, improves resilience and remains workable for management and operational teams.
