Cybersecurity
& Privacy Podcast

CypherTalk is a twice-monthly podcast hosted by Jade Doherty and Dr. Stefan Beyer, Managing Partner at Oak Security, for people who want to understand how security actually works and how to keep themselves and their projects secure. We talk to the researchers finding vulnerabilities before attackers do, the cryptographers building systems that protect millions of people, and the practitioners navigating the gap between security principles and operational reality. Zero-knowledge proofs, smart contract audits, AI-driven threat intelligence, operational security, privacy technology — covered by people who work on these problems every day. For security professionals and anyone who's ever wondered what's really happening beneath the surface of the systems they depend on. No hype. Just signal.

About CypherTalk

CypherTalk is an independent podcast dedicated to cybersecurity, privacy, and the human side of staying safe in a digital world. We sit down with researchers, practitioners, and experts exploring a broad range of topics: operational security, zero-knowledge cryptography, artificial intelligence in both attacks and defences, threat intelligence, privacy technology, and the evolving regulatory and ethical landscape of data protection.

Our guests come from across the security spectrum, including offensive researchers, privacy engineers, threat intelligence analysts, policy experts, and educators. What unites them is a commitment to making complex security topics accessible and actionable.

CypherTalk is educational content first. Whether you're a security professional, a developer, or someone who just wants to understand the threats shaping our digital lives.
