Frequently Asked Questions
What is Splunk used for?
Splunk is primarily used for enterprise security operations (threat detection, incident response, compliance) and IT observability (monitoring, AIOps, application performance). It ingests machine data from across an organization's infrastructure and applies AI-driven analytics to surface insights and automate responses.
Is Splunk part of Cisco?
Yes. Splunk was acquired by Cisco in 2024 and now operates as a Cisco company, with plans to integrate Splunk's security and observability capabilities into Cisco's broader networking and security portfolio.
What is the difference between Splunk SIEM and SOAR?
Splunk's SIEM (Enterprise Security) focuses on collecting, correlating, and analyzing security event data to detect threats. Splunk SOAR (Security Orchestration, Automation and Response) takes action on those detections by automating response workflows, reducing the need for manual analyst intervention.
Does Splunk support cloud environments?
Yes. Splunk offers a Cloud Platform as a fully managed SaaS option, as well as support for hybrid and multi-cloud environments. Its Observability Cloud specifically targets real-time monitoring across cloud-native and distributed systems.
How does Splunk use AI?
Splunk embeds AI throughout its platform — from anomaly detection (UEBA) and automated threat analysis (Attack Analyzer) to AIOps for IT service health, alert noise reduction, and AI-assisted search and investigation workflows within its SecOps and observability products.
