 ## Who should use air-gapped containers?
 
-Air-gapped containers help organizations maintain security in restricted environments:
+Use air-gapped containers if:
 
-- Secure development environments: Prevent containers from accessing unauthorized external services
-- Compliance requirements: Meet regulatory standards that require network isolation
-- Data loss prevention: Block containers from uploading sensitive data to external services
-- Supply chain security: Control which external resources containers can access during builds
-- Corporate network policies: Enforce existing network security policies for containerized applications
+- Your organisation requires containers to communicate only with approved internal services
+- You need to meet compliance standards that mandate network isolation (such as SOC 2, ISO 27001, or PCI DSS)
+- You want to prevent containers from leaking data or reaching unapproved external endpoints during builds or at runtime

-Start with the most restrictive policy and gradually expand based on legitimate business needs:
-
-1. Start with: Docker Official Images and Organization images
-2. Add if needed: Docker Verified Publisher Images for commercial tools

 - Monitor usage patterns: Review which images developers are attempting to pull, identify legitimate requests for additional image types, regularly audit approved image categories for continued relevance, and use Docker Desktop analytics to monitor usage patterns.
-- Regularly review the repository allow list: Periodically audit the repositories in your allow list to ensure they remain necessary and trustworthy, and remove any that are no longer needed or maintained.

+- Regularly review the repository allow list: Periodically audit the repositories in your allowlist to ensure they remain necessary and trustworthy, and remove any that are no longer needed or maintained.
 
 ## Scope and bypass considerations
 
 - Image Access Management only controls access to Docker Hub images. Images from other registries aren't affected by these policies. Use [Registry Access Management](/manuals/enterprise/security/hardened-desktop/registry-access-management.md) to control access to other registries.
 - Users can potentially bypass Image Access Management by signing out of Docker Desktop (unless sign-in is enforced), using images from other registries that aren't restricted, or using registry mirrors or proxies. Enforce sign-in and combine with Registry Access Management for comprehensive control.
 - Image restrictions apply to Dockerfile `FROM` instructions, Docker Compose services using restricted images will fail, multi-stage builds may be affected if intermediate images are restricted, and CI/CD pipelines using diverse image types may be impacted.
