Most companies with networks are faced with the dilemma of having unsupervised employees. This allows employees to go to their favorite online gaming site or waste time in other ways. With Net Spy Pro, a network supervisor can filter this and other types of content on their network. Net Spy Pro can block any web site you specify from ever being launched. When a user tries to go to a web site listed in the supervisor-created block list, their browser will completely close.

In addition to keeping a list of web sites that can't be accessed, a network supervisor can create a list to block specific applications from being launched by keyword. If an application on this user-created block list is clicked on, it will not launch. This allows the network supervisor to restrict certain applications that they do not want their employees to use such as web browsers or chat clients.
