The Prism team builds the systems that turn Elastic Security’s raw data into a trustworthy picture of the users, hosts, and services in a customer’s environment
We power the Entity Store, entity risk scoring, entity resolution, and the data maintainers that analysts rely on to understand who did what, what’s risky, and what to investigate next
