About

I started my professional career in 2005 as a Sales Executive, gaining hands-on experience in direct sales and customer relationship management. After a year in White Goods Maintenance sales, I moved into the Telecommunications industry, where I worked as an Enterprise Account Manager for over two years, managing corporate clients and developing strategic accounts. Since 2008, I have been actively working in the Information Technology sector, and since 2010. I have specialized in Cybersecurity Solutions, building deep expertise in enterprise security, channel development, strategic account management, and business growth across complex enterprise environments. From 2017 to 2026, I was part of Exclusive Networks Türkiye, where I progressed into leadership roles and ultimately served as Director of the Sales Unit. During this journey, I led high-performing teams, managed strategic vendor relationships, expanded partner ecosystems, and drove sustainable business growth within one of the world's leading global value-added distributors. Following this chapter, I joined Vitel as Senior Sales Manager and Team Leader, where I broadened my experience across Cybersecurity, IT Operations Management (ITOM), IT Service Management (ITSM), Endpoint Management, and enterprise IT solutions. Today, I serve as Regional Director – META at Defensium, leading the company's business growth and strategic expansion across the Middle East, Türkiye, and Africa (META) region. At Defensium, I am committed to helping organizations transform the way they investigate, detect, and respond to cyber threats. I strongly believe the future of cybersecurity lies in the convergence of Digital Forensics and Incident Response (DFIR), faster IOC Scanning, Threat Detection, CyberSecurity Operations, CyberSecurity Intelligence. Our mission is not only to detect threats faster but also to empower security teams with intelligent, automated investigation capabilities that enable confident and timely decision-making. Throughout my career, I have remained passionate about building trusted partnerships, developing high-performing teams, and creating measurable business value. I believe leadership is built on trust, continuous learning, and a relentless commitment to innovation. My goal is to help organizations strengthen their cyber resilience while contributing to the evolution of the global cybersecurity ecosystem.
