The Security Manager Office is a
room in the Sarif Industries Headquarters. It is located on the third floor and overlooks the atrium. It features a level 3 secured computer and an unlocked security terminal that controls the building's defenses. During the events of Deus Ex: Human Revolution, the room is occupied by Adam Jensen, who doesn't care to keep the room clean.
Jensen's personal computer can be hacked twice (second time on return visit) or accessed with the password (mandrake) from Pritchard.
Jensen's personal computer is also exploitable to create an 'xp loop' where saving before completing the hack stacks previous experience, making it possible to get maximum augmentations early in the game.
