Hungary’s cybersecurity leadership spans public authorities, telecom and IT services, healthcare, insurance, and multinational enterprises—an ecosystem where security leaders are increasingly expected to balance governance, regulatory alignment, and real-world operational resilience. The professionals below reflect that range: from long-tenured CISOs building mature security governance in large organizations, to leaders shaping programs in regulated public-sector and healthcare environments, to practitioners with strong network and infrastructure roots now translating that expertise into enterprise security strategy.
Lászlóné Gerecsei — Chief Information Security Officer, Szabályozott Tevékenységek Felügyeleti Hatósága
Lászlóné Gerecsei is Chief Information Security Officer at Szabályozott Tevékenységek Felügyeleti Hatósága in Budapest, with a career strongly anchored in Hungarian public-sector institutions and regulated environments. Alongside her full-time CISO role, she has held Chief Information Security Officer responsibilities for multiple organizations in parallel—including Magyarságkutató Intézet (part-time), Budapest Főváros Kormányhivatal (both full-time and part-time periods), and Kelet-Pesti Tankerületi Központ (part-time). Her earlier tenure includes a long period as Informatikai Főkoordinátor at Nemzeti Közlekedési Hatóság and system administration experience at Fejér Megyei Közlekedési Felügyelet. This portfolio signals deep familiarity with governance-heavy operating contexts where security must map cleanly to oversight, policy, and institutional accountability.
István Kalmár — Chief Information Security Officer, PANOR Informatika Zrt.
István Kalmár is Chief Information Security Officer at PANOR Informatika Zrt. in Budapest, after serving as Head of the IT Security Division for several years. His profile is distinctly infrastructure-forward, emphasizing core networking and security domains: TCP/IP routing and switching, major routing protocols (RIP, EIGRP, OSPF, BGP), and enterprise security controls for WAN/Internet environments including firewalls, VPNs, and intrusion prevention systems. He also references governance and regulatory frameworks such as NIST Special Publication 800-53, ISO/IEC 27001, and the Network and Information Security Directive (NIS 2). The tool and vendor surface area he lists—spanning Cisco, HP, Ruckus Wireless, Palo Alto Networks, Riverbed, Extreme Networks, F5, Fortinet, Forcepoint, Aruba, and Check Point—points to a leader comfortable operating across complex enterprise and service-provider-grade environments.
István Hagen — Chief Information Security Officer, Bonafarm Co.
István Hagen serves as Chief Information Security Officer at Bonafarm Co., with a long tenure at the organization and a parallel role as IT specialist and IT security specialist. His experience indicates an operational model where security leadership is closely tied to business demand management and IT operations support—particularly across Villány and Budapest contexts. He explicitly references managing IT-related business demands, and strategic consulting and control of IT security issues, suggesting a pragmatic, business-embedded approach to security governance within a diversified corporate group.
József Bíró — Chief Information Security Officer, Randstad Enterprise
József Bíró is Chief Information Security Officer at Randstad Enterprise, bringing senior management experience across software and cloud services contexts. His stated strengths emphasize information security management and program fundamentals—ISO/IEC 27001, security operations center work, IT service management, IT strategy, and security best practices—supported by advanced security certifications including Certified Information Security Manager (CISM) and Certified Information Systems Security Professional (CISSP), including the Information Systems Security Management Professional concentration. This combination reads like a security leader built for scaling governance and operating models in complex, service-driven environments.
Tibor Bodor — Chief Information Security Officer, 4iG Nyrt.
Tibor Bodor is Chief Information Security Officer at 4iG Nyrt. in Budapest, with an emphasis on information security governance and information security management. His profile highlights ISO/IEC 27001 experience, ethical hacking, and project management—suggesting a mix of governance discipline and hands-on security understanding. In a large technology and services organization, that balance often matters: aligning controls and assurance while keeping a practical view of threat reality and implementation constraints.
Gábor Csehi — Chief Information Security Officer, OKPI – Országos Korányi Pulmonológiai Intézet
Gábor Csehi serves as Chief Information Security Officer at OKPI – Országos Korányi Pulmonológiai Intézet under a contract arrangement, while also acting as Security Liaison Officer at Dél-pesti Centrumkórház – Országos Hematológiai és Infektológiai Intézet. His experience centers on healthcare information technology and information security, with focus areas that include risk analysis and business continuity planning. In healthcare settings—where availability and data protection are inseparable—this kind of dual-role coverage often signals someone operating at the intersection of governance, clinical operations realities, and resilience planning.
György Petercsák — Chief Information Security Officer, Pro Patria Electronics
György Petercsák is Chief Information Security Officer at Pro Patria Electronics in Budapest, following earlier roles inside the same organization that span IT operations and security, and technical project management. His progression includes leadership experience as Chief Executive Officer and Chief Technology Officer at DATA ELEKTRONIK Kft., and earlier public-sector IT management at the Mayor’s Office of District 12, Budapest. Across these roles, the common thread is a blend of operational execution (infrastructure, security controls, and day-to-day IT) and leadership responsibility—an advantage for building security programs that are both implementable and measurable.
Hímer Attila — Chief Information Security Officer, Lechner Tudásközpont
Hímer Attila is Chief Information Security Officer at Lechner Tudásközpont in Budapest. The role placement in a national knowledge/innovation institution context implies a security mandate that likely spans governance, institutional systems protection, and risk oversight across data-heavy operations. His profile is straightforward in title and tenure, signaling a stable CISO appointment within a public-sector-adjacent environment.
Csaba Siket — Chief Information Security Officer, AEGON
Csaba Siket is Chief Information Security Officer at AEGON with a notably long tenure beginning in 2002, including responsibilities framed around security governance and operation, and representation as a Central European information security representative.

Hungary’s Cybersecurity Leaders and the Road Ahead
