Forefront Unified Access Gateway (UAG) enables you to provide remote access to corporate applications and resources for remote employees, mobile workers, partners, and other third-parties. However, providing remote access to applications and resources that are located on your corporate network could potentially lead to security breaches. Forefront UAG helps you to provide secure remote access only to the users and endpoints that you want to allow access to your applications and resources, by using a combination of endpoint health policies, authentication servers, and application access authorization.
