    Abstract: Disclosed herein are system, method, and computer program product embodiments for hybrid-type authorization. An embodiment operates by parsing a policy expression into an abstract syntax tree (AST) and receiving, from a local server, user attribute data of a user. The embodiment further operates by traversing the AST to evaluate the user attribute data and determining whether a result of the traversing is indeterminate. In addition the embodiment operates by sending, to a remote server, a request for additional user attribute data in response to determining that the result is indeterminate, and receiving, from the remote server, the additional user attribute data. Then the embodiment operates by re-traversing the AST to evaluate the user attribute data and the additional user attribute data, authorizing the user based on at least one of the traversing or re-traversing, and outputting an authorization result.
