A first computing device on a first network establishes a secure communications channel with a second computing device on a second network. The first computing device receives, via the secure communications channel from the second computing device, a first software product and a first software product identifier that identifies a previously manufactured first software product. The first computing device obtains first validation information that uniquely identifies the previously manufactured first software product. The first computing device analyzes the first validation information and the first software product to determine whether the first software product is different from the previously manufactured first software product. The first computing device, in response to determining that the first software product is different from the previously manufactured first software product, sends a first message to the second computing device indicating that the first software product is not validated.
