Tenable Names Dino DiMarino CRO to Lead AI Security Push

Introduction

How prepared is your organisation for a cyber threat landscape that AI is making more complex by the day? That's the question Tenable — one of the world's leading cybersecurity companies — is answering with a major leadership move. The company has appointed Dino DiMarino as its new Chief Revenue Officer, tasking him with scaling global sales and accelerating growth in exposure management and AI security. For Indian enterprises and CISOs navigating an increasingly hostile digital environment, this appointment signals where enterprise cybersecurity investment is heading next.

The Big Announcement

Tenable Holdings has appointed Dino DiMarino as Chief Revenue Officer, effective immediately. Based in Boston, DiMarino will lead the company's global sales operations, partner ecosystem, and revenue functions as Tenable doubles down on its exposure management and AI security portfolio for enterprise customers.

DiMarino succeeds Dave Feringa, who retired from the role after a long tenure at the company. He brings over two decades of leadership experience across cybersecurity and technology, having previously served as Chief Revenue Officer at Snyk, Qualys, and Mimecast, and as Chief Executive Officer at AppViewX. Earlier career stints include senior roles at RSA Security and Dell EMC — a CV that covers virtually every major chapter of enterprise cybersecurity's evolution.

Mark Thurmond, Co-CEO of Tenable, described the appointment's strategic intent clearly: the goal is to expand Tenable's global footprint and accelerate pipeline growth with enterprises looking to strengthen their AI exposure management programmes. DiMarino himself noted that AI is rapidly expanding the attack surface — and that Tenable is positioned to help organisations convert security insights into measurable risk reduction.

What This Means for Your Brand

For Indian enterprise brands, this leadership appointment at Tenable is more than a corporate reshuffle. It's a directional signal about where the cybersecurity industry is placing its biggest bets — and Indian CIOs and CISOs need to be paying attention.

AI adoption in India is accelerating across BFSI, healthcare, retail, and manufacturing sectors. With that acceleration comes a proportional expansion of the cyber attack surface. Every new AI tool, every large language model deployment, every automated workflow introduces potential vulnerabilities that traditional security frameworks weren't built to address. Exposure management — identifying, prioritising, and reducing cyber risk across an organisation's entire digital footprint — is precisely the discipline Tenable is investing in.

Consider this for Indian brands: a mid-sized Indian fintech deploying AI-powered credit scoring tools or a healthcare platform using AI for diagnostics is creating new data exposure points daily. Without a structured exposure management approach, these organisations are flying partially blind on risk.

The forward-looking reality? As global cybersecurity vendors like Tenable scale their enterprise sales operations under aggressive new leadership, their India presence — already growing — is likely to intensify. Indian enterprise buyers will have more options, more competition among vendors, and potentially better pricing leverage in the near term.

Expert Take

DiMarino's appointment reflects a broader industry pattern: cybersecurity companies are placing seasoned revenue leaders — not just technical executives — at the top of their commercial functions. This matters because enterprise cybersecurity selling has evolved from product demos to boardroom conversations about risk, compliance, and business continuity.

With over 20 years across Snyk, Qualys, Mimecast, and AppViewX, DiMarino understands both the technology and the commercial complexity of selling security at scale. In India, where cybersecurity spending among enterprises is growing rapidly — NASSCOM estimates the Indian cybersecurity market is on track to reach $5 billion by 2025 — the arrival of aggressive global CROs with expansion mandates translates directly into increased sales activity, partner investments, and local hiring.

For Indian channel partners and resellers in the cybersecurity space, global leadership transitions like this often precede renewed partner programme investment and go-to-market restructuring — worth watching closely.

The brands.in Perspective

India's enterprise sector has long treated cybersecurity as a compliance checkbox rather than a strategic investment. That mindset is being challenged — not gently, but forcefully — by the scale and sophistication of modern cyber threats. Tenable's decision to bring in a high-calibre CRO with an explicit mandate around AI exposure management is a reminder that the global cybersecurity industry is moving fast and expecting enterprise buyers to keep pace. Indian brands that wait for a breach to take exposure management seriously are not being cautious — they are being reckless. Leadership appointments like this one set the commercial agenda. The question is whether Indian enterprises are ready to engage with it.
