1. A data governance system for use with an existing organizational file system, said data governance system comprising a non-transitory, tangible computer-readable medium in which computer program instructions are stored, which instructions, when read by a computer, cause the computer to automatically manage access permissions, said system comprising: a probe engine communicating with said organizational file system and being operative to collect access information from said organizational file system in an ongoing manner; a redundancy reducing engine receiving an output from said probe engine and providing a redundancy reduced information stream; and a redundancy reduced information database receiving and storing said redundancy reduced information stream; said redundancy-reduced information database storing information relating to a subset of a set of access permissions to said organization file system, said subset being created by said redundancy reducing engine, said redundancy reducing engine being operative: to ascertain whether there exists a first subset of said multiplicity of access permissions permitting access to a portion of said organizational file system, which permitted access is identical to access permitted by a second subset, different from said first subset, of said multiplicity of access permissions to said portion of said organizational file system, said first subset of said multiplicity of access permissions therefore being redundant; and responsive to said ascertaining whether any of said access permissions are redundant, to eliminate from said multiplicity of access permissions to said organizational file system, said access permissions to said organizational file system which are redundant.
