CTG Strengthens Cyber Resilience in a Regional Healthcare System

 The Challenge and Opportunity

A large regional healthcare system operating multiple hospitals, medical parks, specialty centers, and an extensive physician network faced growing cybersecurity risk as its digital footprint expanded. Like many healthcare organizations, it operates in a highly regulated environment where downtime directly impacts patient safety, making business continuity critical.

Although foundational security controls were in place, leadership lacked a unified, real-time view of the organization’s security posture and operations. Security data was fragmented across tools, making it difficult to consistently identify, prioritize, and respond to threats. The organization sought to improve visibility, strengthen threat detection and response, and establish a sustainable operating model for managing cyber risk—without disrupting clinical operations.

This created an opportunity to transition from reactive, assessment-driven security activities to a continuous, operational cybersecurity program aligned with healthcare realities. CTG’s mature cybersecurity assessment model and client dashboard—which provides 24x7 end-to-end insight into security operations—made us the ideal partner.

The Solution and Results

CTG partnered with the healthcare system using a phased approach designed to validate risk, establish a strong security baseline, and then operationalize continuous security capabilities.

Phase 1: Baseline and Risk Validation

The initial phase focused on establishing clarity and confidence through:

• A comprehensive cybersecurity assessment aligned to a structured security framework
• External and internal penetration testing to validate real-world exposure
• Identity and cloud security posture analysis to identify priority risk areas
• Foundational security enhancements guided by ranked risk findings

These activities provided leadership with a clear, evidence-based understanding of cyber risk and a practical roadmap for improvement, balancing risk severity, operational impact, and remediation effort.

Phase 2: Operationalizing Cybersecurity

With a prioritized roadmap in place, Phase 2 shifted from understanding the environment to embedding cybersecurity into daily operations through:

• Deployment of full Security Operations Center (SOC) services
• Continuous vulnerability and compliance management
• Managed Detection and Response (MDR) across identity, endpoint, and cloud environments
• 24x7 security monitoring, threat hunting, and incident response
• Ongoing cybersecurity advisory support to align operations, governance, and strategy

This phase shifted the organization from periodic assessments to continuous security operations, improving response readiness while reducing operational burden on internal teams.

Outcomes and Impact

The phased approach delivered meaningful and measurable improvements across the organization:

• Significant reduction in identity-related security risk, reflecting stronger directory hygiene and reduced attack paths
  • 96.5% decrease in PingCastle score
  • 22.4% increase in Microsoft Secure Score
• Steady improvement in cloud security maturity driven by prioritized remediation
• Near real-time visibility into security posture through a centralized security dashboard
• Faster detection and response to security events
• Increased leadership confidence in incident readiness and operational resilience

Most importantly, cybersecurity evolved from a series of disconnected activities into a coordinated, sustainable operating model that supports patient care rather than competing with it.

As a trusted partner, CTG continues to strengthen the client’s security posture with 24x7 managed SOC services, advisory support, and ongoing optimization of security operations to keep pace with evolving threats.
