As a Fractional Virtual CISO, I advise organizations on securing critical IT and OT infrastructure by identifying vulnerabilities across operational technology and manufacturing systems. I analyze regulatory compliance gaps within ISO 27001, TISAX, NIS2, and DORA frameworks, explaining business risks of non-compliance. I execute comprehensive security assessments of converged IT​/​OT environments, precisely identifying critical vulnerabilities and compliance deficiencies. Additionally, I provide strategic threat intelligence for industrial sectors facing sophisticated attacks. I establish robust, cost-effective security operations bridging IT and OT domains, transforming reactive compliance models into proactive threat hunting strategies that ensure regulatory compliance and business resilience.
