Customer Story

California Health System Improves Application and Infrastructure Health with RevealX

The organization is ranked as one of the top not-for-profit hospital systems in the United States, serving more than 100 cities across Northern California.


Maintaining staff members’ access to patient information wherever and whenever they need it, so they can provide the highest quality care to patients.

ExtraHop enables us to quickly troubleshoot and identify the root cause for performance issues that can impact patient care.

CTO California Health System

The Technology Environment

  • More than 20 hospitals and dozens of cancer, cardiac, trauma, and rehabilitation centers
  • Nearly 35,000 applications, including an electronic health record (EHR) system that provides patient care, clinical, and billing functionality
  • A strategic initiative to scale up virtual desktop infrastructure (VDI)


Why the California Health System Chose RevealX

Visibility reduces service disruptions and enables proactive improvements

  • "ExtraHop enables us to understand how our applications work—all 35,000 of them," says the CTO. "We now have performance and security data for everything that communicates on the network."

RevealX provides much-needed insight into VDI stack

  • “I was blind to what was going on in the VDI stack and I knew ExtraHop could enable me to see," the CTO says.

The Outcome

Unmatched Visibility for Better Security and Improved Care

Successful VDI scaling initiative

  • Using ExtraHop to understand both user experience and how well the VDI environment was operating, the team migrated 10,000 desktop PCs to the VDI infrastructure, added over 50,000 subscribers to My Virtual Workspace, and went from zero users to more than 10,000 thin clients in ten hospitals, in a year and a half, with another dozen hospitals planned for the following year.

Keen security insights

  • "ExtraHop is an added layer of security for us,” says the CTO. “Everything communicates across the network and if anything looks suspicious, we can surface these insights up to our security team for further investigation. It's next generation virus definition for network traffic."
  • "We are not allowed to adjust the software on some medical devices that have been FDA certified, which means we cannot deploy some security software on those devices," explains the CTO. "ExtraHop, in combination with other tools, allows us to monitor the communications of those devices on the network and identify non-compliant behavior."

Proactive clinical informatics through HL7 messaging protocol visibility

  • "Imagine being able to access data like bed-count availability and correlate that with information on scheduled discharges. Being able to do that in real-time instead of waiting for the daily report allows us to act in more efficient ways. It could mean being more efficient with our resources and seeing more patients per week," says the CTO.
  • "There's a big focus right now on making sure doctors don't over-prescribe medications and that they don't prescribe particular medications if avoidable. ExtraHop gives us the data and ability we need to act in real time to set up intervention measures if needed—something that has not been possible until now,” explains the CTO.
