Microsoft Forefront Threat Management Gateway (TMG) 2010 Service Pack 1 (SP1) introduces new features and functionality to Forefront TMG 2010 Standard and Enterprise Editions.
The service pack includes the following new features and feature improvements:
The new User Activity report displays the sites and site categories accessed by any user.
All Forefront TMG reports have a new look and feel.
Enhancements to URL Filtering
You can now allow users to override the access restriction on sites blocked by URL filtering. This allows for a more flexible web access policy, in that users can decide for themselves whether to access a blocked site. This is especially useful for websites that have been incorrectly categorized.
You can now override the categorization of a URL on the enterprise level; the override is then effective for each enterprise-joined array.
Denial notification pages can now be customized for your organization's needs.
Enhanced Branch Office Support
Collocation of Forefront TMG and a domain controller on the same server, which can help reduce the total cost of ownership at branch offices.
When installed on a computer running Windows Server 2008 R2, SP1 simplifies the deployment of BranchCache at the branch office, using Forefront TMG as the Hosted Cache server.
Support for publishing SharePoint 2010
Forefront TMG SP1 supports secure publishing of SharePoint 2010.
