Microsoft confirmed to Gardner recently, that the Microsoft Forefront Thread Management Gateway will not continue with a new full version.
Not to continue with an edge protection solution, should be based on a strategic decision at Microsoft, not to compete with vendors in this area anymore.
So current infrastructure with TMG will receive the usual five years lifecycle extended support. But customers can not expect any new product in this area from Microsoft.
We already investigated alternatives in the past months for branch office solutions. As there are some limitations with TMG for such solutions compared for the former ISA versions.
When we finally finished our evaluations about alterntives, I will post information about it.
