About Casey R.

I serve as Field CTO for North America and LATAM at Tenable, where I help organizations transform cybersecurity from a reactive function into a strategic business enabler.With over two decades of experience spanning infrastructure, security engineering, and executive advisory, I bring a rare combination of technical depth and strategic perspective. My career began in data center operations and infrastructure engineering, where I developed a foundational understanding of how complex systems operate at scale. Over time, I expanded into wireless architecture, physical security, disaster recovery, and enterprise security programs—eventually leading critical security initiatives for organizations preparing for public markets.Today, I partner closely with CIOs, CISOs, and executive leadership teams to design and implement exposure management strategies that align security investments with measurable risk reduction. My focus is helping organizations gain clarity from complex security data, prioritize effectively, and build scalable, automation-driven security programs that improve operational efficiency and resilience.Beyond advisory, I remain deeply engaged in advancing security automation. I am the creator of Navi, an open-source platform that operationalizes exposure management through automation and data integration. This work reflects my broader philosophy that modern cybersecurity must evolve into an engineering discipline—one defined by measurable outcomes, intelligent automation, and continuous improvement.My leadership approach is grounded in translating technical complexity into clear strategic direction. I work to empower organizations to move beyond reactive security models toward proactive, data-driven risk management frameworks that support innovation and growth.Core focus areas include:• Exposure management and risk prioritization• Security Automation and Data Engineering• AI-assisted Security Operations• Executive Security Strategy and Transformation• Aligning cybersecurity with business objectivesI am driven by curiosity, continuous learning, and the belief that meaningful innovation happens at the intersection of engineering, leadership, and vision.
