      • Browser Session
      • Browser Hardening
      • Network Protection
      • Extensions
      • Internet Explorer Compatibility Mode
      • Printers
      • Privacy
      • Browser Session

      • The Rule can include Profile configurations that can be configured outside of the Rule. Select Saved profiles to select a preconfigured profile in place of the Data controls.
    5. Save.

    Configure External Controls

    Inline profiles should be configured within the Rules in the Controls sections. This allows you to create specialized rules containing different combinations and configurations of controls.
    The Profiles feature is used when you want to use legacy profiles and add them to the rules.
    Rules can contain either inline data controls or external controls.
    The Controls for the Prisma Access Browser rules are configured internally, within the body of the individual rule. This means that each rule contains its own unique set of controls.
    There are some use cases when you might want to create multiple rules using the same list of controls. To accomplish this task, Prisma Access Browser has a mechanism to create external controls that are not built into a rule but exist separately. Each control defines a particular use case containing configurations for the Policy control types.
