So many press releases before MacWorld.  This is pretty cool.  You can secure your phone to only allow access behind a firewall if the phone is at pre approved locations.  Nice.  Check out the release..

Mobile Active Defense (M.A.D.
Partners, LLC) announces the release of its patent-pending
mobile firewall and contents filtering mechanisms that
enforce controls based upon the physical location of the
mobile device. The award-winning Mobile Enterprise
Compliance and Security Server (MECS) provides stringent and
comprehensive access, security and compliance enforcement
mechanisms to echo fixed enterprise policies.

With the addition of GeoLocation controls, Mobile Active
Defense (M.A.D.) offers organizations around the world a new
range of previously unavailable flexibility over the content
filtering and access rights of iPhones, iPads, smartphones
and tablet devices.
