Splunk Tool

In this tutorial, you will learn about the Splunk tool, key features and benefits for the organizations using the tool.

In today’s digital world, organizations generate massive amounts of data from servers, applications, devices, and user interactions. But raw data alone isn’t useful—it needs to be analyzed to uncover patterns, troubleshoot issues, or detect security threats.

Splunk is a software platform used for searching, monitoring, analyzing, and visualizing machine-generated data such as logs in real time. It helps organizations collect and index large volumes of log data from various sources and turn it into actionable insights.

What is Splunk?

Splunk is a data analytics and monitoring tool that processes unstructured or complex data from virtually any source—like log files, sensors, or cloud services. It indexes this data in real time, allowing users to search, correlate, and visualize it through dashboards and reports. Originally built for IT operations, Splunk now serves industries like cybersecurity, finance, healthcare, and more.

Splunk History

• Founded: 2003 by Michael Baum, Rob Das, and Erik Swan in San Francisco, California.
• Purpose: Initially created to solve IT operational challenges by indexing and searching machine data.
• Product Launch: The first version of Splunk was released in 2006.
• IPO: Splunk went public in 2012 on NASDAQ under the ticker symbol SPLK.
• Growth: Over the years, Splunk expanded its capabilities beyond IT ops to security (SIEM), DevOps, business intelligence, and observability, becoming a leader in log management and data analytics.

To combine Splunk’s data analytics and security capabilities with Cisco’s network and infrastructure offerings, Cisco acquired Splunk for $28 billion.
