Introduction to Rego Training
This Rego training teaches attendees Rego's features and functions, including how Rego is used for policy enforcement, the role of queries and decisions, and how to implement policies. Through hands-on labs, students learn how to create, test, and optimize policies, as well as integrate Rego into sample applications.
