A method of safe file transmission and reputation lookup is provided. As a part of the safe file transmission and reputation lookup methodology, a data file that is to be made available to a data file receiver is accessed and it is determined whether the data file needs to be provided a protective file. The data file is wrapped in a protective file to create a non-executing package file. Access is provided to the non-executing package file where the associated data file is prevented from being executed until data file reputation information is received.
