Marco Bellumore

I’m a Cyber Security Authority Expert focused on designing security architectures, defining security strategies and master plans, and specifying IT/OT security requirements. In my current role, I coordinate OT Security programs and projects, manage cybersecurity risk assessments and remediation plans, and support cybersecurity acceptance testing and supply chain security controls.

Previously, I worked as an OT Cybersecurity Specialist, where I designed and managed network security architecture and supported IT/OT system integrations for automation projects. I also defined and created security and operational policies and documentation, handled endpoint and systems hardening, and led incident response & analysis alongside security project activities and budgets.

Earlier, as a Cybersecurity Specialist, I managed security projects, antimalware/EDR policies and reporting, and performed vulnerability assessments through early warning, security events, and logs analysis. I bring this delivery mindset into recognized assurance work as an Auditor/Lead Auditor for ISO 27001:2022 and Artificial Intelligence ISO/IEC 42001:2023, and I align my practice with standards including ISA/IEC 62443.
