Strengthening Healthcare Security with Sentri-Zone

With over half of physicians feeling unprotected at work, Sentri-Zone offers a proactive shield against the rising tide of healthcare violence.

Physicians are feeling increasingly unsafe. Medical facilities, long viewed as spaces dedicated to healing, are experiencing an alarming rise in threats and violence. The Medscape Physical Security in Medical Workplaces Report 2026, published January 23, 2026, offers one of the most comprehensive data sets to date on how physicians perceive their personal safety across various healthcare settings.

The results are sobering; fewer than half of physicians feel “reasonably” protected from physical harm at work.

Physicians Report Low Confidence in Physical Protection

Across all clinical environments, the report reveals widespread concern:

• Academic and public sector facilities: Only 46% of physicians feel “reasonably” protected—the highest rate of any setting.
• Medical offices: 43% report feeling only “slightly” protected or worse.
• Hospitals and clinics: 40% say they feel “slightly” protected or worse from potential physical attacks.

The data illustrate a clear decline in perceived safety and underscore a growing vulnerability among healthcare professionals.

Why Physician Fear Is Rising

Workplace violence has been escalating for years, and physicians now report that physical security concerns have intensified significantly over the past three years:

• 26% of physicians in medical offices say physical security is “much more important” today
• 30% of physicians in hospitals and clinics report the same

Physicians face threats from both internal aggressors and external sources, including patients, visitors, and even family members. The report highlights that insider-related violence may pose an even more complex risk than external threats.

These findings serve as more than a warning; they represent a call to action for healthcare systems.

The Path Forward: Strengthening the Security Ecosystem

To effectively reduce violence and improve clinician safety, healthcare organizations must take decisive steps, including:

• Enhancing physical security infrastructure
• Expanding workplace violence prevention programs
• Providing consistent de-escalation and emergency response training
• Improving reporting systems and reporting culture
• Investing in staffing and environmental design strategies

Healthcare facilities face unique vulnerabilities: open access, emotionally charged environments, and increasingly volatile interactions. To meet these challenges, many organizations are turning to modern Active Violent Event (AVE) technology, including Sentri-Zone from Crotega.

The Role of Sentri-Zone in Modern Healthcare Security

Sentri-Zone is a patented, ceiling-mounted assailant suppression system designed specifically to deter, disrupt, and delay an active violent perpetrator inside a building. Developed by Crotega, the system delivers rapid, remote-activated defense during the most dangerous moments of an active shooter or violent event—crucial minutes before police arrive.

Sentri-Zone deploys REPULS®, a water-based irritant spray that causes intense but temporary discomfort to the eyes and skin. The resulting disorientation makes it extremely difficult for an attacker to continue aggressive actions.

REPULS is the first approved, non‑aerosol defense spray designed for safe indoor deployment without contaminating sensitive areas within medical facilities. It has successfully passed rigorous evaluations conducted by state health regulators.

Why Sentri-Zone Represents the Next Generation of AVE Technology

1. Rapid, Targeted Deployment
Installed discreetly in ceilings or pendant mounts, Sentri-Zone covers entrances, corridors, lobbies, offices, and other high-risk areas. When triggered, it deploys 10-second bursts of REPULS directly onto the threat location.

2. Intuitive Remote Activation
Authorized personnel can activate the system within seconds using:

• A touchscreen interface
• A hardwired UL-listed control panel

This near-instant activation dramatically reduces response time.

3. Effective Suppression of Violent Behavior
Exposure to REPULS produces:

• Intense eye, nose, and throat irritation
• Involuntary eye closure
• Skin irritation

Together, these effects disrupt an offender’s ability to see, aim, or continue violent behavior.

4. Safe for Evacuation and First Responders
REPULS is not a fog or aerosol; visibility remains clear. Staff and patients can evacuate safely, and law enforcement can enter the area without delay.

5. Filling the Critical Response Gap
Most casualties in active shooter incidents occur within 5–7 minutes, long before police can intervene. Sentri-Zone fills this gap by delivering immediate, on-site suppression at the onset of violence.

6. Scalable and Non-Intrusive
Sentri-Zone integrates into existing buildings without creating visible anxiety-inducing hardware. The system is scalable, discreet, and re-certified annually to maintain readiness.

Strengthening Organizational Reputation and Retention
Healthcare organizations that prioritize safety foster a culture that:

• Enhances physician morale
• Reduces turnover driven by fear
• Supports recruitment and retention of clinical talent

With workplace violence now a daily concern for many physicians, both invisible and visible investments in security technology demonstrate a genuine commitment to staff well-being.

For physicians across the United States, workplace violence is no longer an abstract threat; it is a growing reality that affects personal safety, mental health, and the ability to deliver quality patient care. The evidence is clear: physicians do not feel adequately protected.

Sentri-Zone provides a modern, proactive, and highly effective approach to strengthening security within healthcare environments. By integrating layered physical defenses, improving response times, and reducing risk, the system helps create the safer, more predictable environments physicians need to provide exceptional care.
