Welcome to the Data Security Decoded podcast, brought to you by Rubrik Zero Labs. In each episode, we discuss cybersecurity with thought leaders and industry experts, getting their take on trends, themes, and how they see data security evolving. This is a must-listen for security and IT leaders looking to better understand trends shaping data security and how they can achieve cyber resilience. 

In this episode, our host, Caleb Tolin, is joined by Errol Weiss, Chief Security Officer at Health-ISAC and former cybersecurity leader at Citi and Bank of America. Errol shares his journey from the NSA to building one of the most collaborative threat intelligence networks in healthcare, discussing cyber recovery, the minimum viable hospital model, and why culture and community matter in achieving true resilience.

Errol Weiss has been a driving force in advancing cybersecurity resilience across critical sectors, beginning with his early work at the National Security Agency and later leading security programs at Citi and Bank of America. As Chief Security Officer at Health-ISAC, he built a threat operations center from the ground up, delivering original threat intelligence to healthcare organizations that often lack the resources to do it alone. With deep experience across consulting, finance, and healthcare, Errol has become a leading voice in shifting the conversation from protection to recovery, promoting a resilience-first mindset, collaborative intelligence sharing, and a human-centric security culture.

Join Caleb and Errol as they explore what makes healthcare cybersecurity unique, how to embed security into clinical culture, and why building a “human firewall” is just as critical as any technical control in today’s evolving threat landscape.
