Gurur Yetiskin began his academic and professional journey in Belgium and France, building his foundation in cybersecurity through early work on network security, corporate awareness programs, and application-layer vulnerability research across Antwerp, Brussels, and Paris.

Returning to Türkiye, he developed deep expertise in cloud security, application security, and international project delivery, going on to hold senior consultant and team-leader positions at globally recognized institutions. At Deloitte Risk Advisory, he delivered penetration testing and security audit services to 150+ banks and 50+ multinational enterprises across the financial, telecommunications, pharmaceutical, automotive, and manufacturing sectors. He subsequently led the RSU team at ING Bank as Lead Consultant, owning pentest delivery, vulnerability management programs, and test architecture design. At Paribu, he directed Red and Blue Team operations for crypto-asset infrastructure serving millions of users.

Today, as Cybersecurity Leader at a private holding company, Yetiskin holds end-to-end ownership of security strategy, architectural decisions, threat intelligence, SOC operations, and incident response. The security architectures he designs are aligned with OWASP, NIST, and MITRE ATT&CK, meeting regulatory requirements while effectively managing the organization's risk profile.

Beyond his enterprise responsibilities, he contributes to the global open-source security community as an active member of the OWASP Manchester Chapter. He ranks among the all-time top 50 researchers on the industry's most exclusive bug bounty platforms including Synack Red Team, Yeswehack, and Detectify, and has secured notable placements at international competitions hosted at Black Hat.
