Mattias Pilroth
I work on the strategic and technical foundations of cybersecurity in safety-critical industrial environments.
My focus is on designing resilient OT architectures that hold up when enterprise IT requirements collide with operational reality, long system lifecycles, and constrained connectivity.
Rather than isolated controls, I focus on foundations: identity, trust, network boundaries, and risk management models that can be sustained by the line organization over time.
Areas of focus
- Industrial identity and access foundations
- Risk management through assessments and technical controls
- Network boundaries and segmentation in industrial environments
- Translating regulatory intent into operational engineering
Public technical notes
- ot-security-notes – Ongoing reflections on OT-specific system behavior, risk, and failure modes where traditional IT assumptions break down.
- ot-trust-in-isolated-networks – A focused deep-dive into PKI, certificate validation, and trust management in isolated OT environments.
