I don't know if you've read the two Elder Scrolls novels, The Infernal City and Lord of Souls, but in it you find out that the Penitus Occulatus function half as bodyguards for the Emperor and half a spies. Planting and gathering information, assassinating Imperial enemies, stuff like that. Anyone can join so long as they show proper aptitude.

Obviously Stormcloak fanboys wouldn't be too crazy about it, but it's what we've got.
