My latest video screencast is looking at Bouncer from CoreTrace. They have a new software-only version 6 that provides solid endpoint protection by only allowing vetted applications to run across your enterprise. There are agents for all 32-bit versions of Windows since 2000 and 64-bit Windows 7 and Server 2008.

CoreTrace Bouncer. Pricing begins at $35 per endpoint
