Systems and methods for evaluating security risks using a manufacturer-signed software identification manifest are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: receive a request to perform attestation of a client device; retrieve, from an agent executed by the client device, a manifest comprising: (i) a signature portion encrypted with a first key, and (ii) a software identification (SWID) portion encrypted with a second key; retrieve the first key from a manufacturer database; retrieve the second key from a customer database; decrypt the signature and the manifest with the first and second keys; and perform the attestation using the decrypted manifest.
