À propos de Pau Marc

OT & IIoT cybersecurity leader and IT/OT architect with 8+ years of experience across industrial environments, enterprise IT, and mission-critical operations; combining security, reliability, and real-world delivery.

I currently lead OT & IIoT cybersecurity at Arxada, supporting teams, projects, and technology deployments across 25+ industrial plants worldwide. I focus on making security effective in operational contexts—balancing risk, availability, and the practical constraints of industrial systems.

Alongside this, I lead IT/OT projects through Zammurai, working across industrial automation (PLC, SCADA), IT/OT networking, and secure architecture initiatives; bridging engineering, operations, and security to deliver outcomes that actually stick.

My background also includes experience in regulated banking (monitoring and operations for critical systems at ING Spain) and industrial 5G/telecom environments (monitoring, automation, and tooling at Telefónica Tech). These environments shaped a pragmatic approach to resilience, operational discipline, and change governance under pressure.

I use a structured OT self-assessment approach, the OT Gap-to-Roadmap Assessment (OGRA), aligned with ISA/IEC 62443 and NIST SP 800-82 Rev. 3, aimed at turning gaps into a prioritized, actionable roadmap (quick wins + longer-term architecture and governance improvements).

I combine technical leadership with a strong hands-on foundation that helps me review, challenge, and improve technical and architectural decisions in complex IT/OT settings. Fluent in Spanish and English. Based in Barcelona.
