Dino DiMarino

Dino DiMarino is Chief Revenue Officer at Tenable, where he leads the company's global sales organization, partner ecosystems, government affairs and revenue operations, driving Tenable's next phase of growth as demand surges for exposure management and AI security. A cybersecurity industry veteran with more than 20 years of leadership experience, Dino has spent his career at the intersection of security innovation and the critical sectors that depend on it — insight he brings to conversations about the evolving threat landscape facing power distribution networks and the broader energy grid, from AI-powered attacks to the growing convergence of IT and operational technology (OT) risk. At Tenable, he works at the forefront of helping organizations manage exposure across both IT and OT environments, as the company extends its leadership in exposure management to address AI-driven threats alongside the traditional and industrial systems that power critical infrastructure. 

Prior to Tenable, he served as CEO of AppViewX, a leader in automated certificate lifecycle management, and as CRO at Snyk and Qualys, delivering strong growth at both, following earlier senior leadership roles across the cybersecurity and enterprise technology industry. Dino earned his business administration degree from Wilfrid Laurier University.
