In big organizations, shadow IT (also known as embedded IT, fake IT, stealth IT, rogue IT, feral IT, or
client IT) refers to information technology (IT) systems deployed by departments other than the central
department, to work around the shortcomings of the central information systems. Shadow IT systems are
an important source of innovation, and shadow systems may become prototypes for future central IT
solutions. On the other hand, shadow IT solutions increase risks with organizational requirements for
control, documentation, security, reliability, etc.
