Integration is the architecture.

I design Zero Trust and Agentic AI architecture for complex enterprises and help teams put it into operation.

Integration needs deliberate design.

Your security platforms need to work with the systems you actually run. The same goes for autonomous agents. I design those connections, including the awkward ones around legacy IT and critical infrastructure.

A diagram is useful only if the architecture survives contact with reality.

I’m Nikola Novoselec.

I have spent 16 years turning enterprise complexity into working architecture, including serving since 2022 as lead programme architect and technical lead for the Zero Trust programme at one of Switzerland’s largest critical infrastructure providers.

I also build and operate autonomous AI systems. Keeping a hand in the work matters to me.

Zero Trust & Agentic AI

Security and autonomy, designed together.

Zero Trust

Beyond the perimeter.

Identity, connectivity and policy need to agree. I design their integration across complex hybrid multicloud environments, including the business-critical legacy systems that cannot simply be replaced.

  • Identity
  • Policy
  • Integration

Agentic AI

Autonomy. With intent.

An agent needs a clear boundary for what it may do and a record of what it did. I apply Zero Trust to AI governance and graduated autonomy, using the systems I build and operate as a working reference.

  • Autonomy
  • Attribution
  • Control
