Welcome
Application Control
BigFix Application Control 2.x lets IT administrators centrally manage and enforce application allowlisting on Windows endpoints using Windows Defender Application Control (WDAC). Built on BigFix, it delivers kernel-level execution control, deny-by-default policy enforcement, TPM-backed code signing, and compliance-ready audit reporting across the enterprise.
Application Control v1.0.0 (To be deprecated)
BigFix Application Control v1.0.0 is a lightweight, native enforcement system for managing application execution across enterprise endpoints. It delivers policy-driven application control within BigFix, enabling IT administrators to enforce usage policies with real-time monitoring and streamlined exception management.

Blocked Application Notifications
When an end user on a BigFix Application Control-managed Windows endpoint attempts to launch a blocklisted or unauthorized application, the system immediately displays a pop-up notification indicating the application is blocked. The user can either close the notification and contact their administrator for more information, or click the Request Access button to submit a formal application exception request.

Lifecycle guides in PDF format
Following is a list of links to the BigFix Lifecycle guides in PDF format:
Software Distribution
Use the BigFix Software Distribution applications to deploy software to endpoints across your network from a single location. Maintain control and visibility into software delivery and installation. Device owners can use the Self Service Application to manage software and other BigFix actions that are deployed to them as offers.
OS Deployment
BigFix OS Deployment, which is part of the BigFix Lifecycle Management suite, provides a consolidated, comprehensive solution to quickly deploy new workstations and servers throughout a network from a single, centralized location. This solution saves time and money, enforces a standardized and approved image, and reduces risks associated with non-compliant or insecure configurations.
Remote Control
BigFix Remote Control application helps to communicate between different components, clients, and endpoints within BigFix environment.
Power Management
Use Power Management to control, monitor, and manage conservation policies in your deployment.
Application Control
BigFix Application Control 2.x lets IT administrators centrally manage and enforce application allowlisting on Windows endpoints using Windows Defender Application Control (WDAC). Built on BigFix, it delivers kernel-level execution control, deny-by-default policy enforcement, TPM-backed code signing, and compliance-ready audit reporting across the enterprise.
- Application Control 2.x
  BigFix® Application Control 2.x uses Windows Defender Application Control (WDAC) as its enforcement engine to apply application allowlisting and blocklisting policies at the kernel level across managed Windows endpoints — centrally managed through the BigFix® Console without relying on Group Policy Objects or separate tools.
- Migrate AC v1.0.0 to v2.x
  Migrate from the custom BAC rule engine in BigFix Application Control v1.0.0 to the Windows Defender Application Control (WDAC)-based enforcement model in v2.x. This one-time, non-reversible six-step process exports existing allowlist rules for recreation as WDAC Supplemental Policies, removes v1.0.0 BAC components from endpoints, deploys a WDAC base policy, and verifies policy activation across managed endpoints.
- Application Control v1.0.0 (To be deprecated)
  BigFix Application Control v1.0.0 is a lightweight, native enforcement system for managing application execution across enterprise endpoints. It delivers policy-driven application control within BigFix, enabling IT administrators to enforce usage policies with real-time monitoring and streamlined exception management.

    - Application Control Overview
      BigFix Application Control is a native, Windows Defender Application Control (WDAC)-based, policy-driven enforcement system for comprehensive application management across enterprise Windows endpoints. IT administrators gain real-time visibility and granular control over application execution; endpoint users are protected by automated policy enforcement with a clear, self-service exception request workflow for legitimate access when an application is blocked.
    - Blocked Application Notifications
      When an end user on a BigFix Application Control-managed Windows endpoint attempts to launch a blocklisted or unauthorized application, the system immediately displays a pop-up notification indicating the application is blocked. The user can either close the notification and contact their administrator for more information, or click the Request Access button to submit a formal application exception request.
    - Raise Application Exception Request
      End users on BigFix Application Control-managed endpoints can raise a temporary exception request for a blocklisted application directly from the blocked application notification using the Request Access button. The request requires a business justification and a valid start-to-end date window; it is routed to the organization's exception manager for approval via a ServiceNow ticket, and the application is automatically re-blocked after the end date. A maximum of 60 exception requests can be raised per endpoint.
    - View Exception Request Tickets
      End users on BigFix Application Control-managed endpoints can view all the application exception request tickets they have self-raised by accessing the My Approvals section in the ServiceNow™ service portal. From the All Approvals screen, click any ticket number to open the Approval Form and see its full details. Users can only view their own exception request tickets.

Blocked Application Notifications in BigFix Application Control

When an end user on a BigFix Application Control-managed Windows endpoint attempts to launch a blocklisted or unauthorized application, the system immediately displays a pop-up notification indicating the application is blocked. The user can either close the notification and contact their administrator for more information, or click the Request Access button to submit a formal application exception request.

In a managed device with BigFix® Application Control installed, if any end user attempts to run a blocklisted application or process, they will receive a notification informing them that the application is blocked on the endpoint. The notification message looks like this:

BigFix Application Control pop-up notification dialog on a managed Windows endpoint showing that an application has been blocked by policy. The dialog displays the name of the blocked application, a message indicating the application is not permitted to run, a Request Access button to initiate a formal exception request, and an option to close the notification and contact the administrator. — Figure 1. BigFix Application Control — Application Blocked Notification Dialog on Managed Windows Endpoint

In such a scenario, a user can take either of the following steps:

close the notification and contact his organization’s BigFix Lifecycle Application Control admin for more information or
raise an application exception request using the Request Access button.
