Strategy, Not Hype: Building a Zero Trust Hospital

One of the most effective—and forward-thinking—frameworks healthcare organizations can embrace to bolster cybersecurity is called Zero Trust. But what does Zero Trust really mean in a healthcare context, and how can it be applied without getting lost in the noise of industry buzzwords? Tamer Baker, Healthcare CTO, and Steven Hajny, Healthcare Technology Evangelist at Zscaler, joined us at the ViVE Conference in Nashville to demystify this concept. With more than a decade of experience delivering secure solutions to healthcare, the duo introduced their new book series, Zero Trust Hospital, designed specifically to help organizations adapt to this paradigm. One book speaks to CxOs and executive decision-makers, while the other is an in-depth guide for architects and IT professionals.

Cutting Through the Buzzword Confusion

Baker and Hajny don’t shy away from acknowledging that “Zero Trust” has become a marketing mantra in many circles—sometimes overhyped or dismissed as too complex to implement. Yet, they argue that when stripped of the “marketecture,” Zero Trust represents one of the most important shifts in modern cybersecurity.

Traditional, perimeter-based security models—which the duo jokingly call “1999 architecture”—constructed protective walls around networks but often couldn’t adapt to today’s threats like phishing, ransomware, and advanced malware. Zero Trust reframes this approach entirely, focusing not on borders but on ensuring that every interaction, user, and device is authenticated, authorized, and encrypted in real time. This granular approach replaces static defenses with dynamic, certificate-based transactions, making it both more flexible and resilient for increasingly fragmented healthcare environments.

Debunking Misconceptions: Security Doesn’t Have to Slow You Down

One common myth surrounding Zero Trust is that it inherently makes workflows clunky or less efficient—a dealbreaker for fast-paced hospital environments. However, Hajny and Baker share evidence to the contrary. For example, they describe an organization where improved cybersecurity measures actually increased radiology productivity, allowing more images to be processed per provider. Such stories challenge assumptions that enhancing security comes at the cost of user experience or operational speed.

And what about implementation timelines? The idea of a multi-year migration can be intimidating, but Baker and Hajny point to examples that defy this perception. They mention how an organization of 50,000 users successfully rolled out Zero Trust in just three weeks—achieved by a single, highly capable intern. While this scenario may be atypical, it demonstrates that with focused efforts, Zero Trust doesn’t have to be an overwhelming undertaking.

Driving Adoption Across Organizations

Implementing Zero Trust isn’t just about deploying new technology; it’s about fostering buy-in at all levels of the organization. Baker and Hajny emphasize the Zero Trust Hospital books (Did I mention you can download them for FREE?) are designed to bridge knowledge gaps and help tackle common obstacles—particularly the “inertia” that can keep a hospital tied to outdated security frameworks. Packed with practical strategies and real-world use cases, these resources aim to empower leadership teams and IT departments to work toward Zero Trust together.

Importantly, Zero Trust isn’t limited to large healthcare systems. Baker and Hajny stress that organizations of any size can benefit from adopting the framework, even incrementally. By addressing misconceptions and offering clear implementation pathways, the books provide a blueprint for creating a security posture that balances protection with performance.
