Splunk

Splunk is a US vendor spanning data analytics and security monitoring. Cisco owns the company, whose flagship Splunk Enterprise platform helps organisations collect and analyse operational data. That combination places Splunk across routine technology management and cyber defence, where the same data can expose service problems and suspicious activity.

Security-monitoring products occupy a sensitive position inside an organisation. They need broad visibility across systems to identify unusual behaviour, so defenders depend on their availability and Integrity. A weakness in this layer can create a separate problem from a flaw in an ordinary business application: the tool used to observe an intrusion may itself need urgent protection. Splunk Enterprise therefore matters both as an analytics platform and as part of the defensive systems that watch the wider technology estate.
