Brook Colangelo has the tough task of keeping the White House's users online and their systems secure. Colangelo is responsible not only for the desktops and servers at 1600 Pennsylvania Ave., but also for making sure that President Obama's BlackBerry isn't hacked.
Colangelo's team remedied a problem the previous administration had with lost email by implementing an EMC archiving system that prevents unauthorized access to the backups. He's also developing a strategy for how the White House can leverage cloud computing.
Colangelo was previously CIO of the Democratic National Convention, and he assisted Obama's transition team on tech issues. Before that, he managed IT for the American Red Cross.
