As healthcare organizations accelerate digital transformation, cybersecurity has become inseparable from patient safety, clinical continuity, and organizational trust. From electronic health records and connected medical devices to cloud platforms and third-party vendors, today’s healthcare environments are more interconnected, and more exposed than ever before.

For OneZero Solutions, addressing that reality starts with a philosophy that places people at the center of every technical decision.

“At OneZero, ‘Customer First. People Always.’ is not a slogan, it is an operating principle,” says John Christly, Vice President of Commercial Services. “In healthcare and other mission-critical environments, cybersecurity decisions are inseparable from human outcomes.”

Christly explains that every control, recommendation, and incident response plan is evaluated through the lens of how it affects patient safety, clinical workflows, and frontline staff. “Our role is to reduce risk without introducing unnecessary complexity, ensuring security supports care delivery rather than obstructing it,” he says.

Where Healthcare Cyber Risk Often Hides

According to Christly, many of today’s most significant healthcare cybersecurity risks stem from a convergence of aging infrastructure, rapid digitization, and ongoing staffing constraints.

“Many healthcare organizations are operating with legacy systems that were never designed for today’s threat environment,” he says. “Yet those systems are now deeply interconnected with cloud platforms, third-party vendors, and remote access technologies.”

Unexpected vulnerabilities often emerge at the boundaries between traditional silos. Christly points to medical devices, operational technology, identity and access management, and third-party integrations as areas where visibility and governance are frequently inconsistent.

“We also see organizations underestimate how quickly a non-clinical system compromise, such as billing, scheduling, or facilities management, can cascade into clinical disruption,” he says. “Attackers understand this interconnectedness and increasingly exploit it.”

Applying National Security Discipline to Civilian Healthcare

OneZero’s work spans federal, defense, and private-sector clients, an experience Christly says directly informs the company’s healthcare approach.

“Our cross-sector experience allows us to bring disciplined, battle-tested practices into civilian environments in a way that is pragmatic rather than bureaucratic,” he says.

Federal and defense work requires rigor in risk management, resilience planning, documentation, and accountability, principles that are increasingly relevant to healthcare as regulatory scrutiny intensifies.

“What we translate is not complexity, but maturity,” Christly explains. “Healthcare organizations benefit from structured approaches to governance, incident response, supply chain risk, and continuity planning that have long been standard in national security and critical infrastructure sectors.”

Crucially, those practices are adapted to healthcare’s pace and resource realities. “We tailor those practices to fit healthcare’s culture, ensuring they are achievable and sustainable,” he says.

Designing Cybersecurity for Real-World Stress

While cybersecurity is often framed as a technical discipline, Christly emphasizes that breaches ultimately affect people and patient care.

“We deliberately design cybersecurity programs to function under stress, not just on paper,” he says. “Advanced monitoring and technical controls are important, but they are ineffective if people do not understand how to act on them during an incident.”

OneZero integrates cybersecurity directly into operational workflows, focusing on role clarity, decision paths, and scenario-based exercises that include clinical, administrative, and executive stakeholders.

“When an incident occurs, the goal is not perfect technical response,” Christly says. “It is calm, informed action that protects patients, maintains trust, and restores operations quickly.”

Executive-Level Guidance Without Overload

For healthcare organizations without in-house cybersecurity leadership, OneZero’s Virtual Chief Information Security Officer (vCISO) and cyber risk management services provide executive-level guidance without the burden of a full-time role.

“Many healthcare organizations do not need a full-time executive cybersecurity role, but they do need executive-level guidance,” Christly says. “Our Virtual Chief Information Security Officer model provides that leadership without the overhead.”

He adds that OneZero acts as an extension of the leadership team, helping organizations prioritize risk, align security with care and business objectives, and make defensible investment decisions.

“Importantly, we absorb complexity on behalf of our clients,” Christly says. “We translate regulatory requirements, risk assessments, and technical findings into clear, actionable guidance.”

Preparing for the Next Five Years

Looking ahead, Christly says healthcare leaders must shift from a prevention-only mindset to one centered on resilience.

“No organization can assume it will avoid incidents entirely,” he says. “The differentiator will be how quickly and safely operations can continue and recover.”

Key trends include increased regulatory expectations for cybersecurity governance, deeper scrutiny of third-party and supply chain risk, and growing convergence between information technology and clinical and operational systems. Artificial intelligence will further raise the stakes on both sides of the threat landscape.

“Organizations that invest now in visibility, identity management, workforce training, and incident preparedness will be far better positioned than those that focus solely on perimeter defenses,” Christly says.

Trust as the Ultimate Measure

At its core, Christly says healthcare cybersecurity is about trust.

“Patients trust providers with their lives and their most sensitive information,” he says. “Maintaining that trust requires more than compliance or technology—it requires leadership, empathy, and preparedness.”

At OneZero, we view our role as helping healthcare organizations build confidence,” he adds. “Confidence that their systems support care, that their teams know what to do when challenges arise, and that security is an enabler of mission, not a barrier.”
