Industrial Cybersecurity Architect

Designing resilient cybersecurity for industrial systems where operational reality dictates the architecture.

I build the strategic and technical foundations for security in safety-critical environments. My work centers on OT architectures that survive the friction of long lifecycles, constrained connectivity, and the requirement for continuous production.

Rather than advocating for isolated controls, I prioritize durable foundations—identity, trust, and network boundaries—that can be sustained by the line organization over time.

Core Disciplines

Identity Architecture: Designing access foundations that persist across the system lifecycle.
Grounded Risk Management: Moving from compliance checklists to technically viable controls.
Infrastructure Boundaries: Practical network segmentation patterns for continuous operations.
Regulatory Engineering: Bridging the gap between legislative intent (NIS2) and plant-floor reality.

Writing

Analysis and working notes on OT security architecture, operational constraints, and failure patterns in high-consequence industrial environments.

Operational Resilience & OT Security
Analytical papers on structural constraints, failure patterns, and consequence-driven security in high-consequence industrial environments. Covers identity, trust, and the limits of compliance-driven programs.
OT Security Notes
Working notes and developing thinking. Earlier drafts, fragments, and ideas that have not yet resolved into finished analysis.
