About Don Ringelestein

I am an enterprise technology and cybersecurity executive with more than 18 years of experience leading complex IT organizations at scale. My leadership integrates infrastructure strategy, security operations, risk governance, and digital transformation.I have directed enterprise infrastructure modernization initiatives while simultaneously building and maturing cybersecurity programs — including full SIEM implementation, centralized log management architecture, and executive oversight of Manager Security Services Providers in 24x7x365 security monitoring environments. My focus is not simply deploying tools, but aligning telemetry, identity governance, zero-trust network security, cloud services, and incident response into a cohesive and measurable security operations model.I translate technical complexity into operational resilience and board-level risk clarity. I am particularly focused on the responsible integration of AI and automation into enterprise environments — leveraging intelligent analytics to enhance threat detection, streamline operations, and improve executive decision visibility while maintaining strong governance controls.Whether strengthening hybrid infrastructure, formalizing identity and access controls, or aligning programs to NIST and CIS frameworks, my work centers on integrating performance, protection, and trust.Earlier in my career, I led multi-site private-sector technical operations, helping standardize and scale service delivery models nationally — experience that continues to inform my disciplined, business-aligned approach to enterprise technology leadership.Certifications: CISSP | CISM | ITIL v4
