The New Identity Crisis: A Conversation with Avihay Nathan, SVP of AI at CyberArk

The New Identity Crisis: A Conversation with Avihay Nathan, SVP of AI at CyberArk

In the age of AI agents, cybersecurity is shifting from focusing on identity to addressing agency. Autonomous agents, which act and reason like humans but operate at machine speed, are being created on the fly. Traditional identity management tools—like user directories and group policies—are ill-equipped to handle these ephemeral, unpredictable entities that can take action and disappear before a human can even react.


CyberArk’s SVP and Head of AI, Data & Research, Avihay Nathan, describes this as an unprecedented challenge. His team is tackling it with a three-part framework:

  • Secure from AI: Defending against new AI-driven threats.

  • Secure with AI: Using AI to augment human defenders and reduce alert fatigue.

  • Secure of AI: Protecting organizations from the AI systems they themselves are deploying.


Many companies are overwhelmed by the rapid adoption of agents without understanding what data or systems these agents can access. This creates a trust crisis, and they are now looking to security vendors for solutions.


CyberArk is mapping out a new agent lifecycle, from discovery (how many agents spun up?) to observability, access control, behavior monitoring, and governance. The key insight is that securing these agents requires understanding their context: what data they touch, what tasks they perform, and why they act in a certain way. An agent's behavior is often "zero-shot," meaning it can act without a history, so context is the only way to anchor and secure its actions.


To build this new vision, CyberArk underwent its own transformation, shifting from a traditional company to an AI-native startup mindset. This involved creating a centralized AI and data group with full ownership and educating the entire organization on the importance of data.


Avihay believes the proliferation of agents will continue as companies prioritize productivity. The new security promise is not just to block threats, but to enable innovation—helping organizations adopt these powerful new technologies both confidently and safely.

The Human Zero Day Series | Ep1161: Dr. Joshua Scarpino: Personalizing Security Culture

From phishing tests to AI-driven impersonation scams, Joshua Scarpino has seen firsthand how the human element remains the most critical factor in cybersecurity. Drawing on his experience across organizations from NIST to Trust Engine, he explains why technology alone can’t safeguard an enterprise. Instead, effective defense comes from a culture where security is personal—linked to daily habits and values employees carry beyond the workplace. With threats evolving faster than traditional training can adapt, Scarpino shares how bite-sized, relevant, and personalized awareness programs not only reduce risk but transform how teams think, act, and protect.

The Human Zero Day Series | Ep1160: Ira Winkler: Awareness Is Not a Strategy

How do you protect an organization when every link in the chain can—and will—fail? Ira Winkler, NSA veteran and author of You Can Stop Stupid, unpacks why human error isn’t the root of security breaches—it’s the visible tip of deeper systemic gaps. From smashing the myth of awareness-as-strategy to advocating for consequence-driven behavior change, Ira brings sharp wit and decades of hands-on insight. His stories span black-bag hacks, social engineering triumphs, and boardroom-level shifts needed to reimagine how we address human vulnerabilities in a world of zero days.

The Human Zero Day Series | Ep1159: Daniel Flowe: Building Trust in Digital Identity

What happens when your “meatspace” identity can no longer keep up with your digital life? Daniel Flowe, Head of Digital Identity at the London Stock Exchange Group, takes us inside the tectonic shift reshaping how we verify who we are online. From the flaws of content-based systems to the promise—and risks—of government-issued e-IDs, he unpacks what equitable, secure, and scalable identity should look like in an AI-infused world. With insights drawn from India, Africa, and beyond, Daniel reveals why the West is lagging—and what we must do to catch up.

The Human Zero Day Series | Ep1158: Beni Beeri Issembert: Who Am I in AI?

The Human Zero Day Series | Ep1158: Beni Beeri Issembert: Who Am I in AI?

Beni Beeri Issembert’s journey from aspiring philosopher to Head of AI Research and Ethics at Metaphysic is anything but linear. With a deep reverence for Nietzsche and an early curiosity about ethics in technology—long before it became a buzzword—Beni brings a rare perspective to synthetic media and AI. In this thought-provoking conversation, he explores how deepfakes challenge our sense of truth, what it means to have an identity in a world of synthetic realities, and why human discernment remains our most powerful tool. As AI continues to blur the lines between real and fake, Beni offers a hopeful yet grounded view on how we might navigate the future—with integrity, curiosity, and resilience.

The Human Zero Day Series | Ep1157: Akis Papadopoulos: Verifying What’s Real

Years before deepfakes hit the mainstream, Akis Papadopoulos was already sounding the alarm. From early GAN breakthroughs to today’s ultra-realistic, low-res media threats, he’s led research at the intersection of AI, media forensics, and public trust. In this episode, he explores why detection alone isn’t enough—and how explainability, user experience, and civic responsibility must shape our response to synthetic media.

The Human Zero Day Series | Ep1156: Ilke Demir: Detecting Deepfakes by Heart

Ilke Demir’s journey from computational geometry to combating deepfakes began with a question: what makes something truly human? At Intel’s Trusted Media team, she developed FakeCatcher, a tool that detects deepfakes using biological signals like heart rate. In this episode, she unpacks the technical, ethical, and social layers of media trust, explaining why provenance and human perception matter as much as detection. Her insights reveal how defending truth in the AI age isn’t just about better algorithms—it’s about understanding people.
