02THE THESIS

One blueprint,
top to bottom.

Most firms either secure your tenant or help with AI pilots. We treat them as one: architecture for production AI, built on a security foundation that makes it safe to ship.

One foundation underneath. Every agent on top.

03Enterprise security

AI doesn’t change
the fundamentals.

AI doesn’t replace Zero Trust principles — it requires them.

Every agent, another actor. Every tool, another permission. Every document, another exposure.

That is why the foundation still comes first: identities, devices, apps, data, clouds, AI.

04Enterprise AI

Any model. Any agent.
Same architecture.

Each team builds agents that know their work, use approved tools, and leave evidence behind.

05About

Founded by three engineers,
deep in the stack.

Everything we’d deploy for you, we run ourselves first. The blueprint isn’t theory. It’s how we operate.

Philippe Meerbergen

The one who keeps asking what the business is actually trying to do. Twelve years drawing the line between secure enough and over-engineered. Managed security at Proximus, senior consulting at IBM, identity research for the European Commission before identity was the perimeter.

M.Sc. Applied Economic Sciences, Business Engineer.

Marnik Bruyndonckx

The one who reads the release notes. Platform hardening and the newer parts of the stack, where documentation runs thin and you build to find out. Five years at Proximus before this, ending as Product Owner of its detection & response service.

B.Sc. Information Management & Security

Tom De Backer

The one who keeps pushing until the thing ships. Eight years keeping client environments standing: tenant hardening, baselines, drift detection, the unglamorous half that decides whether the rest worked. Most of those years at Proximus, ending as Delivery Lead.

M.Sc. Civil Engineer - Industrial Engineering & Operations Research · M.Sc. Industrial Engineer - Electronics & ICT.
