About Nadir

Throughout my career, I have successfully delivered results by integrating security into the core of business operations. My key strengths include:

Strategic Security & Compliance Leadership: I am responsible for the entire Information Security Management System (ISMS) based on ISO 27001:2022 and ISO 27701 standards. I have extensive experience in implementing and auditing these frameworks, as well as ensuring compliance with GDPR, KVKK, COBIT, SOX and other global data privacy regulations.
Holistic IT/OT Security Management: I possess unique expertise in securing both Information Technology (IT) and Operational Technology (OT) environments. My work with SCADAfence on critical infrastructure and my management of IT/OT security remediations demonstrate my ability to protect complex, hybrid ecosystems against modern threats.
Advanced Security Operations (SecOps): I have hands-on experience building and leading Security Operations Centers (SOC). I led the implementation and management of cutting-edge tools like CrowdStrike EDR, IBM Qradar, Netskope and Cortex XSOAR, enhancing threat hunting, incident response, DLP and vulnerability management capabilities.
End-to-End IT Infrastructure & Project Management: , where I managed a multi-million dollar budget and led projects from data center design to SCADA IT implementation, has provided me with a robust understanding of the IT landscape necessary to support and secure business-critical systems.
I am particularly adept at translating technical risks into business terms for executive stakeholders and fostering a culture of security awareness.I am confident that my blend of strategic governance, technical proficiency, and practical management experience would make me a valuable asset to your team.
