BlueHat (or Blue Hat or Blue-Hat) is a term used to refer to outside computer security consulting firms that are employed to bug test a system prior to its launch, looking for exploits so they can be closed. Their role involves searching for weaknesses or security gaps that could be exploited, and their aim is to rectify and close these potential vulnerabilities prior to a product or system launch.[1] In particular, Microsoft uses the term to refer to the computer security professionals they invited to find the vulnerability of their products, such as Windows.[2][3][4]
