TrustNun is a service that compares file contents and file hashes with "known good" files from ICS/SCADA installation media.
Maybe you prefer not to upload files to our service and would rather have an onsite version of TrustNun? Maybe you simply desire access to the raw data that powers TrustNun? If this is the case, please send us an email @ contact@qedsecure.com and we can work something out
