Reducing Phishing Click Rates by 74% Across a Regional Hospital Network
A regional hospital network handling thousands of patient records daily faced a growing wave of targeted phishing attacks. With clinical staff under constant time pressure and limited cybersecurity training, the organization needed a practical, non-disruptive way to build human-layer resilience — without pulling staff away from patient care.
The Challenge
Healthcare organizations are prime targets for credential theft and ransomware. The hospital's security team needed to transform staff behavior without disrupting clinical workflows.
- Phishing click rates exceeding 38% among clinical and administrative staff
- Limited security awareness — staff trained only once per year via static compliance modules
- High exposure to targeted spear-phishing campaigns impersonating internal systems
- Regulatory pressure from NIS2 and national health data protection requirements
The Solution
AI-powered phishing simulations were deployed across all departments, automatically adapting difficulty based on each employee's risk profile and response patterns — with zero disruption to clinical operations.
- Continuous, realistic phishing simulations tailored to healthcare-specific attack vectors
- Automated risk scoring and adaptive training paths per employee
- Instant micro-training at the moment of failure — directly in the workflow
- Executive dashboards tracking department-level risk and compliance readiness
Deployed by ZeroLayer
ZeroLayer deployed Arsen across the entire hospital network — configuring healthcare-specific simulation scenarios, integrating with the organization's email infrastructure, and establishing automated training workflows. Full deployment was completed within 10 days with no impact on clinical systems.
Arsen"Before this, over a third of our staff fell for well-crafted phishing emails. Now the click rate is in single digits and reporting has gone up significantly. It changed how our people think about email security."
