McAfee and Riverbed Technology 
Riverbed’s RSP is a virtualized, extensible data services platform that runs on the Steelhead hardware. McAfee Web Gateway Security can now run on the virtualized machine. Riverbed said there is no performance degradation and various redundancy features have been included to avoid a single point of failure. McAfee Firewall Enterprise software has previously been offered on the RSP.
