St. Luke’s University Health Network used Security Copilot in Microsoft Defender as the “connective tissue” across its security stack. By doing this, they reimagined how their teams work with alerts, access controls, and vulnerabilities. Instead of jumping between separate tools, Security Copilot provided a single, AI-powered, agentic view of their environment. This consolidated view helped analysts see related alerts together, understand access risks faster, and spot vulnerabilities in context. As a result, their security operations became more coordinated and easier to manage day to day.

St. Luke’s reports saving **nearly 200 hours every month** by using Security Copilot in Microsoft Defender. Those time savings come from: - Reducing manual investigation work across multiple tools - Speeding up triage of alerts - Making it easier to understand access controls and vulnerabilities in one place By freeing up close to 200 hours monthly, their security team can shift more effort from routine, repetitive tasks to higher-value work like proactive threat hunting and improving overall security posture.

For teams like the one at St. Luke’s, Security Copilot reshapes daily security work by: - **Consolidating signals**: Bringing alerts, access control data, and vulnerability information into a single, AI-assisted view. - **Providing agentic assistance**: Acting as an AI-powered agent that helps interpret signals, surface what matters, and guide next steps. - **Reducing context switching**: Analysts spend less time moving between tools and more time making decisions. Because Security Copilot is integrated with Microsoft Defender and Microsoft Sentinel, it helps security staff move from reactive, ticket-by-ticket work toward a more strategic, insight-driven approach—while still handling the day-to-day alert load more efficiently.
