Managed Detection & Response (MDR) | SIEM | Endpoint Security | Vulnerability Management | Network & Cloud Operations

Executive summary

A privately held women's healthcare provider with a large, distributed footprint needed a security partner that could deliver 24x7 monitoring, rapid response, and a program that fit a mid-sized healthcare budget. After an initial risk assessment and security engineering engagement, STIGroup expanded support into a transparent, co-managed security services model that combined SIEM-based monitoring, endpoint protection and monitoring, and comprehensive vulnerability management across internal and external assets. Over time, the partnership grew to include network operations support and Microsoft cloud engineering to help mature endpoint and device management.

At a glance

Organization profile	Multi-state women's healthcare network with 150+ outpatient locations and hundreds of providers across the Northeast and Midwest.
Primary challenges	Need for responsive endpoint and log monitoring, improved visibility, and scalable security operations under healthcare budget constraints.
Services delivered	Managed SIEM monitoring and response, endpoint security monitoring, internal and external vulnerability scanning, security program consulting, network monitoring/support, and Microsoft Intune advisory and engineering.
Engagement model	Co-managed, transparent partnership: the client retains console visibility while STIGroup designs, configures, and operates the security program.

 

Client profile

The client is a national women's healthcare provider operating a large number of outpatient locations across multiple states. Clinical services include routine and specialty OB/GYN care, diagnostics and imaging, and other women's health services. The organization relies on a combination of on-premises systems at care sites and cloud services that support clinical workflows, making consistent security visibility and control a critical requirement.

Challenges

• Distributed footprint: 100+ sites with a mix of on-premises equipment and cloud services required consistent monitoring and vulnerability management.
• Operational responsiveness: the incumbent endpoint MDR provider often took up to a full day to respond to requests, creating risk and friction for the internal IT team.
• Environment-specific context: the client needed a partner who could understand its unique clinical and operational technology landscape, not a one-size-fits-all service.
• Healthcare constraints: HIPAA-aligned governance and reporting were required, while maintaining cost discipline typical of mid-sized healthcare organizations.

 

STIGroup approach

STIGroup partnered with the client through a phased roadmap that started with assessment and engineering, then expanded into 24x7 managed security services and supporting IT operations. The approach emphasized transparency, practical risk reduction, and progressive expansion as needs and priorities evolved.

Phase 1 - Establish a risk-informed baseline

• Conducted HIPAA-focused security risk assessment activities and targeted security engineering to prioritize improvements.

Phase 2 - Build a security monitoring foundation

• Implemented managed SIEM services by collecting and correlating logs from critical systems and security platforms to enable faster detection and response.

Phase 3 - Expand into endpoint security monitoring

• Transitioned endpoint monitoring and response to STIGroup to improve responsiveness and align endpoint telemetry with SIEM monitoring.

Phase 4 - Broaden continuous risk reduction

• Expanded vulnerability management to include both external and internal scanning, with actionable reporting and remediation guidance.

Phase 5 - Extend into IT operations where it mattered most

• Added network monitoring/support and Microsoft cloud engineering, including Intune advisory and implementation support, to strengthen security and reliability.

Solution

STIGroup delivered an integrated set of managed services and advisory support tailored to the client's environment:

• 24x7 security monitoring and incident response support, aligned to the client's operational needs and escalation preferences.
• Managed SIEM program: log onboarding, correlation, alert tuning, investigation workflows, and reporting to demonstrate program health and value.
• Endpoint security monitoring and response using an industry-leading endpoint detection and response platform, integrated with SIEM monitoring.
• External and internal vulnerability scanning with prioritization guidance to focus remediation effort where risk is highest.
• Security program consulting: threat awareness and risk advisories, and periodic governance touchpoints with IT leadership.
• Tabletop exercises for both IT and executive leadership to test readiness and improve decision-making during incidents.
• Quarterly participation in the client's Information Security Committee meetings to review monitoring outcomes, risk themes, and next-step recommendations.
• Network monitoring and support services for troubleshooting, administration, and targeted operational tasks.
• Microsoft cloud engineering and Intune advisory to mature device management and support security hardening initiatives.

Outcomes

• Improved responsiveness and collaboration: the client gained a partner that understood its environment and could respond rapidly to operational needs.
• Consolidated security visibility: endpoint telemetry, security alerts, and critical system logs were brought together to support faster investigation and decision-making.
• Expanded continuous risk management: internal and external vulnerability scanning helped the organization identify and prioritize remediation across a broad footprint.
• Greater transparency: the co-managed model provided direct client visibility into security tooling, alerts, and configurations rather than a black-box experience.
• Broader operational support: the relationship expanded beyond monitoring into network operations and Microsoft cloud initiatives to address real-world constraints in healthcare IT.

Why STIGroup

The client selected and retained STIGroup because we combined enterprise-grade capabilities with the flexibility and attention required by mid-sized healthcare organizations:

• Responsive service backed by a 24x7 SOC and on-call escalation model.
• Environment-specific expertise: a partner that learns the client's technology landscape and adapts monitoring, workflows, and guidance accordingly.
• Transparent operations: shared visibility and collaboration rather than black-box monitoring.
• Practical cost discipline: right-sized solutions and phased expansion to align to budget and priorities.
• One partner across security and critical IT operations, reducing friction between tools, teams, and vendors.
