Ep910: Keren Leshem | CEO and Board Director, OCON healthcare

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.

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.

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.

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.
