Hi Kerry Kidwell,
Thank you for posting in the Microsoft Community Forums.
Cloud-based trusted signatures are typically implemented through online services that verify the integrity and trustworthiness of software and provide digital signatures for the software. Although these services are cloud-based, they can often be verified and integrated on local servers as well.
The local server may communicate with the cloud service to verify the signature and integrity of the software. The local server may send hashes or other identifiers of the software to the cloud service and receive the corresponding signature verification results from the cloud service. This integrated approach ensures the security and integrity of the software in the local environment while taking advantage of the cloud service for verification.
Thus, while cloud-based trusted signatures are primarily provided through online services, they can often be integrated and used with local servers to meet the security needs of a business or organization.
Best regards
