Employees create and use their own IT resources that are invisible to IT department. This is known as shadow IT, when IT department oversees and manages IT resources. Everest Group predicts that more than 50% of technology spending in organizations was due to shadow IT. Shadow IT is wide-spread and growing, so it's a matter of managing the risk. The rise of cloud technology compounds this problem, making it easier than ever for employees to use unapproved IT resources. Shadow IT increases the risk of security breaches, as resources are outside IT departments' control.
