The following is provided by Forefront TMG Update 1:

• SafeSearch Enforcement. Forefront TMG can enforce blocking adult text, images and videos from search results by popular search engines. SafeSearch can be enforced on specific groups or to the entire organization.
• Including non-primary URL filtering categorizations. Forefront TMG uses an algorithm to select a URL’s “primary” category from among up to four categorizations provided by Microsoft Reputation Services (MRS). In Update 1 you can control access to sites that match any of the non-primary categorizations provided by MRS. For example, a URL with a primary categorization of News can now match a rule by any of its non-primary categorizations (such as Web Mail).
• Support for Exchange 2010 SP1
• Bug fixes and various other improvements. For details, see http://go.microsoft.com/fwlink/?LinkId=201151.
