About Mark Lezerkiewicz

I’m a business minded security leader and engineer at heart — inventive, relatable, and committed to delivering secure multi-cloud environments in highly regulated, complex industries. I connect strategy to execution to drive results at an enterprise scale. My experience spans IAM/PKI, cloud posture and code protection, data protection, threat and vulnerability management, and zero trust adoption — all with a focus on creating value. I lead cross-functional teams, diverse portfolios, and delivered enterprise-scale security capabilities across industries. I’ve secured the most critical payment systems that run the world’s financial backbone, processing trillions in daily transactions, and modernized the core security functions — launching and enhancing more than a dozen enterprise services serving thousands of institutions. I lead architecture and engineering efforts end-to-end — designing secure, scalable solutions, building them into production-ready systems, and then operating them at enterprise scale with high availability, resilience, and measurable results. My work blends engineering depth and product thinking — from defining the vision and securing executive sponsorship, to aligning roadmaps with operational requirements and delivering against strict audit and regulatory standards. I’m an expert in translating enterprise policy into actionable controls, conducting readiness reviews, and ensuring compliance with NIST 800-53, NIST CSF, ISO 27001, FedRAMP, SOX, PCI DSS, GDPR. I lead with clarity, ownership, and trust — mentoring talent, creating sustainable systems, and ensuring security enables the mission when there is no margin for error…
