As organizations globally grapple with a rapidly expanding and increasingly complex digital attack surface, the integration of artificial intelligence into both defensive and offensive cyber operations has marked a pivotal turning point for the industry. In a significant strategic move designed to harness this technological shift, cybersecurity firm Tenable announced on December 15, 2025, that it has appointed Vlad Korsunsky, a seasoned technology executive from Microsoft, to the dual positions of Chief Technology Officer and Managing Director of Tenable Israel. This high-level appointment is poised to accelerate the company’s dominance in the exposure management sector by placing a proven innovator at the helm of its long-term technological vision. Reporting directly to co-CEO Steve Vintz from the Tenable Israel Innovation Center in Tel Aviv, Korsunsky is now tasked with scaling the flagship Tenable One Exposure Management Platform and, most critically, spearheading the advancement of the company’s AI strategy to meet the next generation of cyber threats head-on.

During his time at the software giant, Korsunsky was instrumental in building and leading global businesses centered on multi-cloud security, enterprise AI security, and exposure management—domains that align perfectly with Tenable’s core mission. His contributions were pivotal in not only shaping Microsoft’s overarching security strategy for artificial intelligence but also in creating disruptive new business lines that addressed emerging market needs. This extensive experience in architecting and scaling security solutions for some of the world’s most demanding enterprise environments positions him as a key asset for Tenable’s ambitious growth and innovation plans.
The decision to bring Korsunsky on board is a direct response to a cybersecurity landscape being fundamentally reshaped by artificial intelligence and the growing necessity for comprehensive, platform-based security solutions. Tenable’s co-CEO, Steve Vintz, described Korsunsky as a “visionary technology leader,” emphasizing that his unique expertise is essential for advancing the company’s exposure management vision and satisfying the surging demand for robust AI risk management. As attackers increasingly leverage AI to automate and sophisticate their methods, defensive strategies must evolve in lockstep. Korsunsky’s proven ability to navigate this complex intersection of AI and security is expected to fortify the Tenable One platform, ensuring it provides customers with the predictive and preventative capabilities needed to stay ahead of adversaries. This strategic hire underscores Tenable’s commitment to investing in top-tier talent to solve the most pressing security challenges facing modern enterprises.

In his capacity as Chief Technology Officer, Vlad Korsunsky assumes direct responsibility for guiding Tenable’s long-term technological trajectory, overseeing its overarching technical vision, platform strategy, and culture of innovation. A central pillar of his mandate will be to continue scaling the Tenable One Exposure Management Platform, a comprehensive solution designed to provide organizations with a unified view of their entire attack surface. Beyond platform enhancement, his most crucial task is to spearhead the advancement of the company’s AI strategy. This involves embedding sophisticated AI and machine learning capabilities deep within Tenable’s product ecosystem to deliver more accurate threat predictions, automate vulnerability prioritization, and provide actionable insights that empower security teams to act decisively. His leadership is expected to unify Tenable’s global engineering efforts and accelerate the delivery of cutting-edge features that address the nuanced challenges of securing cloud environments, operational technology, and identity systems.
The appointment of a leader with Korsunsky’s credentials signaled a clear and decisive investment by Tenable to solidify its market leadership in the face of an AI-driven paradigm shift.
