Splunk Inc. is a San Francisco-based multinational company whose software platform indexes machine data, and makes it searchable so it can be turned into actionable intelligence. The Splunk platform aggregates and analyzes digital exhaust from various sources, including application program interface (API) pulls and log files from applications, servers, mobile devices and websites. Turning machine data into operational intelligence helps Splunk's customers gain an understanding of what’s happening across their IT systems and technology infrastructure in real-time in order to facilitate data-driven decision management.
Splunk’s log-management and analysis platform uses its proprietary Search Processing Language for traversing large data sets of machine data and executing contextual queries. Machine data, the fastest-growing area of big data in the enterprise, includes every user transaction, system message, suspicious activity and machine-to-machine (M2M) interaction. Often dubbed the "Google for logfiles," Splunk also bills itself as a security information and event management (SIEM) company. SIEM is essentially log management as applied to security: by unifying logfile data gathered from various systems and devices across an IT environment, users can perform high-level security analyses and assessments of the state of their systems from a single interface.
Named after spelunking, which is the exploration of caves, Splunk was founded in 2003 and became public in 2012. Key verticals that Splunk serves are communications, energy and utilities, financial services, health care, higher education, manufacturing, non-profit, online services, public sector and retail. The company continues to expand through acquisitions, such as the 2013 purchase of Bugsense, a mobile-device data-analytics company, and the 2015 buyout of cybersecurity startup Caspida. In February 2018, Splunk announced plans to acquire Phantom Cyber Corp., which provides security automation and orchestration tools.
