Case Study

Rebuilding Security Operations in Just Over Two Weeks with Microsoft Sentinel and Managed Detection & Response

A global healthcare and life sciences leader with more than 19,000 employees and 50+ facilities worldwide was plagued by alert fatigue and poor visibility from its existing SIEM, with an incumbent MSSP that lacked urgency ahead of an expiring contract. Netrix deployed Microsoft Sentinel and delivered fully managed MDR through its Security Operations Center, standing up the new environment in just over two weeks. Daily security data visibility grew from roughly 10-12 GB to about 500 GB, dramatically reducing alert noise and establishing a trusted, ongoing cybersecurity partnership.

The Client

A global healthcare and life sciences leader with more than 19,000 employees, over 50 facilities worldwide, and responsibility for supporting more than 1,000 customer programs sought to transform its cybersecurity operations and eliminate security monitoring inefficiencies.

The Challenge

The organization's existing SIEM environment generated excessive noise while providing insufficient visibility into actual threats. Key challenges included:

  • Alert fatigue caused by poor-quality detections
  • Limited useful security telemetry
  • Significant security visibility gaps
  • Lack of urgency from the incumbent MSSP
  • Need for a trusted consultative cybersecurity partner
  • Tight transition timelines due to expiring provider agreements

The company viewed the initiative as a complete cybersecurity reset rather than a simple technology replacement.

The Solution

Netrix implemented Microsoft Sentinel and delivered fully managed MDR services through the Netrix Security Operations Center (SOC). Key components included:

  • Microsoft Sentinel deployment and configuration
  • Microsoft 365 E5 enablement
  • Security Orchestration, Automation and Response (SOAR)
  • 24x7x365 monitoring and investigation
  • Human analyst validation of alerts
  • Ongoing cybersecurity advisory and optimization

The project scope covered:

  • Approximately 4,000 servers
  • 12,000 endpoints
  • 24,000 identities across employees, contractors, and vendors worldwide

To me, it's about the trust and the partnership. We're getting great service for what we're paying, as well as the knowledge base that we didn't have before.

The Implementation

  • Full security operations review and redesign
  • Rapid Sentinel deployment
  • MDR onboarding
  • SIEM optimization and tuning
  • Security monitoring modernization
  • Continuous collaboration with internal teams
