Cisco made another move to the vertical security space yesterday. They bought a company for $51M and 27 people that provides them video surveillance capabilities. This acquisition maps well to what they’ve done well, meaning buying smaller innovative teams that address an enterprise vertical need. And, it seems a sure thing that other Security vendors should be concerned. The reason I say that? They have a “Director of Security for Worldwide Channels”. Nobody does that unless they are extremely aggressive about a vertical space.
