Summary
👤
Senior🎓
Top SchoolFrank Leitner is a cybersecurity consultant based in Germany with nine years of focused experience bringing industrial product security into compliance with standards like IEC 62443 and the EU Cyber Resilience Act. He has led product security for Siemens SIMATIC visualization and engineering systems, driving threat modeling, gap analyses, security requirements, architecture, and verification across complex OT/industrial software. Frank blends deep embedded and software development roots (ARM, QNX, C++, real-time systems) with pragmatic security program design, having created secure development guidelines and supported ISO27001 and SDLC integration. He frequently acts as the bridge between development teams and certification requirements, translating regulatory needs into testable implementation and verification steps. Now leading his own consultancy, he helps product organizations operationalize resilience where many struggle to meet new EU and IEC mandates. An early career background in CAD/CAM tooling and cross-border engineering projects gives him a rare combination of low-level technical fluency and applied product-security strategy.
