Hospitals, clinics and healthcare in general have a lot of data to deal with. Tracking of a vast amount of data and making sense of it in real time and semi-real time can be a real challenge. In this blog, we'll take a look at how Splunk can help the healthcare professional to know what devices are connected to their network.
Cisco bought Splunk to integrate the unique capabilities of the tool into the wider Cisco eco-system. Splunk allows us to take various sources of information and to analyse those sources and display the outcomes on a dashboard. The ability to cross-correlate data from more than one source is a pretty interesting capability - a bit like an artist building up the full picture with added brushstrokes, Splunk adds more detail as we add more data sources.

Just before we run through the solution with Splunk, let's take a look at a closer analysis of why hospitals and healthcare in particular can benefit from this solution.
There are many verticals that could use the functionality that we're going to run through in this blog, but to start with, let's take a look a case study in Healthcare.
The question is with the Splunk IT Service Intelligence (ITSI) deployment is how does this help a hospital? To answer that, we need to dive a little more into how a hospital operates.
The key challenge is the sheer number of devices - there are many laptops, biomedical equipment types, guest users and so on.
A large amount of mobile equipment is difficult to track and determine the base use case: what is plugged into my network?
There are a unique set of factors that every healthcare professional will recognise:
That's a lot of moving parts to track! Staff in hospitals need some help to keep track of what's connected - and where they can find it when they need.
At the core of the challenge is visibility. BioMedical equipment in particular are very expensive assets - one patient monitor can exceed $5000 for a single unit. These assets need to be used as much as possible - but also to know where spare ones are, when needed.
Hospitals operate with an enormous number of connected assets—clinical devices, biomedical equipment, staff laptops, guest devices, and third-party systems. Many of these devices are mobile, shared, or temporarily connected, making it difficult to answer fundamental questions such as:

With Splunk ITSI, we can ingest multiple sources of data, allowing us to cross correlate. Even taking a single source of data, we can show what's connected to the network and where.
In this case study, we have worked with a clinical client to build out a system to help track assets. As with an investment - for any business, but in particular healthcare - the return on investment is important.
Here's a shortlist of reasons why it's worth investing the effort to build out the capability:
1. Speed and Operational Efficiency
Traditionally, tracking down equipment or diagnosing issues requires logging into multiple systems—often by specialised IT staff with the necessary access and expertise. This approach is slow, resource-intensive, and unsustainable in high-pressure clinical environments.
With Splunk ITSI dashboards, clinicians, operations teams, and IT staff gain rapid, role-based access to the insights they need—reducing investigation time and allowing issues to be resolved before they impact patient care.
2. Deeper Insight into Biomedical and Clinical Assets
Splunk ITSI enables deeper analysis through filtering, correlation, and rule-based logic. For example:
These insights directly support patient safety, asset utilisation, and regulatory compliance, all while improving clinical efficiency.
3. Executive and Management Reporting
Healthcare leadership teams require clear, timely insight into system availability, risk, and performance—without placing additional strain on already stretched ICT teams.
Splunk ITSI provides live and semi-live (it depends on the information source we are ingesting), intuitive dashboards that allow executives and managers to:
This self-service access reduces dependency on manual reporting while strengthening governance and accountability.
The Hospital and Clinical case study is all about providing visibility into what is connected at a clinical site. This allows the tracking of devices and can help spot anomalies and issues. When you're dealing with as many devices as a hospital does, this can be invaluable.

In the lab image from below, we can see the overview of the data (we have used a lab example, so there's no real clinical data here).
This is an easy-to-use dashboard that’s taken data from an API and displayed it in a accessible format.
The data can now be filtered – we’ve put in a filter to view all Apple devices and the data below shows the specific detail on those.
This simple dashboard allows the clinical staff to:

What are the next steps? Really that depends on what you want to extract from the data.
Adding some rules means we can extract data that meets those rules – this could be looking for suspicious devices for example:
As for the visuals, Splunk has its Dashboard Studio to be able to generate ITSI Glass tables, such as the one shown below. This allows us to overlay our live data onto maps and other images, which makes this a really visually appealing option:

This blog has highlighted the unique intersection of factors in healthcare environments that make it difficult for staff to find and maintain a vast array of equipment.
Part of the solution is being able to locate devices when they're needed - and sometimes that has to be quickly. Occasionally a device gets lost, so knowing where it was last seen can be a major help in finding that device and returning it to service.
All clinical professionals are busy, so any help we can offer using IT Service Intelligence can help to make their lives a little easier.
