Case Study: McKesson Health Solutions achieves 90% reduction in MTTR and 75% faster Citrix launches with ExtraHop

McKesson Makes Application Hosting for Hospitals Faster, More Efficient

McKesson Managed Services hosts hospitals’ clinical, financial, and EHR applications and must meet strict performance-based SLAs while rapidly expanding its customer base and infrastructure. As the environment grew more complex, the team could no longer rely on assembling specialists to diagnose problems quickly, putting SLAs and efficient operations at risk.

By deploying ExtraHop to analyze real-time wire data, McKesson gained correlated, cross-tier visibility to triage and troubleshoot issues—uncovering, for example, failed DNS lookups that reduced Citrix launch times from 40 to 12 seconds. The change delivered a 90% reduction in MTTR, a 75% improvement in Citrix performance, avoidance of SLA penalties, retirement of legacy tools, and more than $660,000 in annual savings (including over $260,000 in staffing reductions).
