Tenable has appointed Vlad Korsunsky as Chief Technology Officer, bringing onboard a seasoned technology leader with 25+ years of experience in cybersecurity, cloud platforms, and software engineering.Korsunsky joins from Microsoft, where he led critical initiatives across cloud, enterprise, and AI security, operating at the intersection of large-scale platforms and emerging threat landscapes. In his new role, he will define Tenable’s long-term technology vision, scale the Tenable One exposure management platform, and deepen the company’s AI-driven risk and exposure management capabilities.This appointment signals a decisive move by Tenable to lead cybersecurity’s next phase where AI expands both the attack surface and the defence toolkit.
Why This Appointment Matters
Cybersecurity has entered an era where traditional vulnerability management is no longer sufficient. AI, cloud-native architectures, identity sprawl, and third-party dependencies have dramatically expanded enterprise exposure.
Tenable’s leadership move reflects several market realities:
- AI is reshaping how threats are created, scaled, and automated
- Security leaders need unified visibility across cloud, identity, and AI systems
- Exposure management—not point security—is becoming the dominant model
- Platforms must scale with enterprise complexity and speed
Hiring a CTO with deep experience inside Microsoft’s global security engine positions Tenable to operate at enterprise scale, with AI-native thinking baked into its roadmap.
What Vlad Korsunsky Brings to Tenable
At Microsoft, Korsunsky worked on some of the most complex security challenges in the industry—protecting massive cloud environments, enterprise customers, and AI-driven workloads.
At Tenable, his mandate includes:
- Shaping long-term technology and platform strategy
- Scaling Tenable One as a unified exposure management system
- Strengthening AI-driven analytics and risk prioritisation
- Addressing emerging AI-specific risks across enterprises
- Translating deep security telemetry into actionable business insight
His background uniquely aligns with Tenable’s goal of moving beyond “finding vulnerabilities” to measuring, prioritising, and reducing real-world cyber exposure.
Leadership Perspective: Platform Leadership in an AI-Driven Threat Landscape
Steve Vintz, Co-CEO of Tenable, highlighted the strategic importance of the appointment:
“Vlad is a visionary technology leader who has operated and succeeded at the highest levels of the industry. As we boldly advance our exposure management vision, he is exactly the leader we need to accelerate our platform leadership, especially with rising demand for AI risk management.”
The emphasis is clear: AI risk management is no longer optional it’s core to enterprise security strategy.
CTO Perspective: Exposure Management for the AI Age
Commenting on his appointment, Vlad Korsunsky said:
“Tenable is the defining leader in exposure management, with unmatched breadth and depth of coverage, analytics and expertise. We are uniquely positioned for this moment, where AI is not only reshaping how we work, but also the attack landscape and how it is defended.”
His statement underscores a critical shift:
AI is simultaneously a productivity multiplier and a threat accelerator and security platforms must evolve accordingly.
The Bigger Trend: From Vulnerabilities to Exposure Intelligence
Tenable’s move reflects a broader transformation in cybersecurity:
- Enterprises want risk context, not raw alerts
- Security teams need prioritisation tied to business impact
- AI-driven analytics are becoming essential for scale
- Boards and CISOs are demanding exposure-level visibility
Exposure management platforms that unify assets, identities, cloud workloads, and AI systems are emerging as the new control plane for cyber risk.
Strategic Signal to the Market
By appointing a CTO with deep hyperscaler and AI security experience, Tenable is sending a clear signal:
- It is building for enterprise-scale complexity
- AI risk is a first-class security problem
- Platform depth matters more than tool sprawl
- Long-term leadership requires architectural vision
This positions Tenable strongly as organisations rethink security strategies for AI-first environments.
Vlad Korsunsky’s appointment as CTO marks a pivotal moment for Tenable as exposure management evolves into a core enterprise security discipline.With AI reshaping both offence and defence, Tenable is doubling down on platform leadership, intelligence-driven risk reduction, and future-ready security architecture.This isn’t just a leadership hire.It’s a strategic bet on how cybersecurity will be built, scaled, and governed in the AI era.
