Following My Passion: Joining Linx Security as CTO to Evolve Identity Security

Identity security is broken. And attackers know it.

After more than 25 years in the cyber arena, approaching challenges from different angles and perspectives, one thing has remained clear: identity security is one of the most critical areas in the field—but one where innovation hasn’t kept pace with the evolving threat landscape and business reality.

For years, organizations have struggled to secure identity, not because they weren’t trying, but because the tools they relied on weren’t built for the way modern enterprises operate. Identity is no longer confined to a corporate perimeter. It spans SaaS applications, cloud workloads, privileged accounts, third-party integrations, and an increasingly complex hybrid environment. Yet, the security solutions designed to protect these identities have failed to keep pace.

I’ve seen this challenge firsthand throughout my career - at the Israeli Prime Minister’s Office, at Microsoft, and at Payoneer. And I’ve seen how slow the security industry has been to adapt.

Linx Security is different. And that’s why I’m here.

The Identity Problem No One Wants to Talk About

Enterprise security has undergone a massive shift in the past decade. We’ve moved from firewalls and VPNs to zero trust architectures, cloud-native security, and AI-driven threat detection. Yet, despite all this innovation, identity security has remained stubbornly stuck in the past.

Here’s the reality:

• Most enterprises don’t know who has access to what. Identity data is scattered across countless applications, directories, and systems - leaving security teams with incomplete visibility.

• Access isn’t static - but identity security often is. Enterprises are still using periodic certifications and manual reviews to govern access, while attackers are exploiting identity gaps in real time.

• Legacy solutions weren’t built for today’s cloud-first world. Traditional identity governance was designed for an era of on-prem directories and corporate networks. In today’s decentralized, API-driven ecosystems, these models break down.

The result? Identity is the single largest attack vector today - and the traditional solutions meant to address it are falling short.

Why Linx Security?

Linx Security is solving this problem at its core. Instead of treating identity as just another compliance checkbox, Linx has built an AI-driven platform that continuously maps, monitors, and mitigates identity risk in real time. It provides complete visibility across the modern enterprise—not just who has access, but what they’re doing with it, and what risks that creates.

This is what enterprises desperately need: a way to not just govern identity but to truly secure it—proactively, continuously, and at scale.

Beyond the technology, what truly sets Linx apart is the exceptionally talented team behind it. From world-class security experts to visionary builders, Linx has assembled a group of people who don’t just understand the challenges of identity security—they’ve lived them. What unites them is a shared sense of purpose and a deep commitment to helping customers solve real, urgent problems. The culture here is one of relentless innovation, deep collaboration, and an unshakable drive to make a meaningful impact. It’s a team that moves fast, thinks big, and is driven by a shared mission: to redefine how enterprises secure identity in a world where the old approaches no longer work.

At the heart of it all are the founders—CEO, Israel Duanis, and CPO, Niv Goldenberg—deeply experienced, visionary leaders who have built and scaled security products at the highest levels. What stood out most to me was their deep knowledge of security, their unwavering focus on customers, their ability to build and inspire a world-class team, and their bold approach to innovation. They’ve created a culture where solving real customer problems is the driving force, where top talent thrives, and where big ideas are turned into action.

When I first encountered Linx, it reminded me of the early days of some of the biggest shifts in enterprise security—when companies like Microsoft, Wiz, and CrowdStrike redefined their categories. Linx is doing the same for identity security.

Bringing Enterprise-Scale Security Innovation to Identity

I’ve spent my career scaling security solutions for some of the world’s most complex environments.

At Microsoft, as Vice President of Product & Engineering, I led the integration of CyberX, Aorato, and Adallom into Microsoft’s security ecosystem—transforming best-in-class security technologies into enterprise-ready solutions used by Fortune 500 companies.

At Payoneer, as CTO, I drove platform innovation and system modernization, securing one of the largest global financial infrastructures—enabling businesses to scale securely without compromising compliance.

Now, at Linx, I see a once-in-a-decade opportunity to redefine how enterprises protect identity.

The Future of Identity Security Starts Now

Linx Security isn’t just building another security product. We’re building the future of identity security.

The old ways—reactive identity governance, slow certification cycles, and fragmented visibility—have run its course. Attackers move fast, and security teams need solutions that can move faster.

That’s what we’re delivering at Linx.

I’m excited to be part of this journey—working with a team of security veterans, builders, and innovators to solve one of cybersecurity’s biggest challenges.
