What it stops someone saturating your bandwidth, and stops someone impersonating your TCP sequence and IP while DoS'ing you to steal a session?
If it does it's the only firewall in the world that can do all this, there is no firewall in existence that will prevent bandwidth being filled up, or the classic hijack attack. It is possible to prevent usage of all resources, this is done with either dedicated Layer 7 attack mitigation hardware or through ASIC based appliances utilising SYN cookies and broken packet filtering techniques such as boxes from Top Layer.
Sygate certainly does absolutely nothing against this.
