What is Splunk?

Splunk Inc. is a technology company that produces software for searching, monitoring, and analyzing machine-generated big data, via a web-style interface.

Splunk's software is designed to help users make sense of the vast amount of data generated by their technology infrastructure, security systems, and business applications. The primary use cases for Splunk include IT operations management, security information and event management (SIEM), and log management.

The core product is Splunk Enterprise, which allows users to collect, index, and visualize large volumes of machine data from various sources such as websites, applications, sensors, devices, and systems. Splunk makes it possible to search, correlate, analyze, monitor, and report on this data in real-time. This capability is critical for troubleshooting, security incident response, operational intelligence, and as a tool for decision-making.

Splunk has expanded its offerings over the years to include:

  • Splunk Cloud: The cloud-hosted version of Splunk Enterprise, offering the same features but without the need for customers to manage the underlying infrastructure.
  • Splunk Light: A lighter version of Splunk designed for small IT environments.
  • Splunk Enterprise Security (ES): An analytics-driven SIEM solution that provides insights into security postures and threats.
  • Splunk IT Service Intelligence (ITSI): A machine learning-powered monitoring and analytics solution designed to optimize IT service performance and availability.
  • Splunk User Behavior Analytics (UBA): Uses machine learning and AI to detect insider threats and external attacks.
