Traditional Security Lagging against the Scale of the Cloud

I came away from HP Protect 2013 wondering if current security sold by the traditional security players will actually scale to the hybrid cloud? Are these security tools still system-centric or are they moving to data-, user-, and app-centric? I feel that this move has started but has far to go. I do not think many of the current batch of traditional security services implemented in data centers today can scale properly.
