TMG or UAG? What is the difference?

TMG is an outgoing proxy that protects your internal users from malware, viruses and the like. TMG generates some great web proxy log files to import into WebSpy Vantage allowing you to monitor where your users are going on the Internet, how much they’re downloading etc.  TMG, unlike ISA, now has deep packet inspection for HTTPS traffic, plus a bunch of other new features.

UAG is an incoming proxy that provides employees, partners and vendors secure remote access to corporate resources such as Outlook Web Access (OWA) and Sharepoint (MOSS). It utilizes the TMG engine, but this is mainly just to protect the UAG server (more on this topic here http://technet.microsoft.com/en-us/library/ee522953.aspx).

TMG can also publish your OWA and MOSS sites, but this is no longer recommended by Microsoft. They recommend using a dedicated UAG server to perform this function.
