Splunk UBA (User behavior analytics) is a legacy standalone product that integrates with Splunk ES but requires separate management and workflows. Splunk UBA reached End of Sale in December 2025, and End of Support is in January 2027. UEBA, by contrast, is built natively into Splunk ES Premier, offering advanced unsupervised machine learning, broader behavior coverage (including users, devices, cloud, and applications), real-time risk scoring, and integrated investigation workflows. UEBA provides a more unified, efficient, and powerful security operations experience.
