Because auditors assess implementations of systems, and VMware Cloud is an implementation of VMware’s infrastructure products, VMware can certify the environments against common regulatory frameworks.
VMware keeps a record of these certifications at the VMware Cloud Trust Center:

Given the Shared Responsibility Model, certifications of infrastructure do not carry over to workloads themselves but do help organizations conduct audits faster because third-party auditors already certify the infrastructure, with the results posted in the VMware Cloud Trust Center or available under non-disclosure agreement via account teams.
