Senior Cybersecurity GRC Analyst at Mondelēz International, advancing security governance and compliance.

Greece
Message

At Mondelēz International, I work as a Senior Cybersecurity GRC Analyst. My information security work spans regulated sectors including healthcare, energy, critical infrastructure, financial services, and FMCG/food.

At XM, I orchestrated security and privacy incident response and embedded NIST and OWASP frameworks into data protection policies and system architectures. I also conducted a proof of concept and onboarded a third-party risk management platform.

At HEDNO S.A., I governed GDPR and ISO 27001 compliance and translated compliance gaps into prioritized remediation roadmaps. Earlier, at AidPlusCare (APC), I led ISO 27001 and HIPAA audit and certification programs and operationalized GDPR compliance.
