Subprocessor register
B5 Secure runs on a single hyperscale provider — Microsoft Azure — which keeps our subprocessor footprint deliberately small. The register below lists each subprocessor, its role, the data it may handle, and its processing location. Material changes are notified in advance per our DPA.
Items marked (confirm) are representative categories pending finalization of the vendor set — replace or remove before publication. Microsoft Azure operates under its own SOC 2, ISO 27001/27017/27018, and FedRAMP authorizations; Azure’s compliance documentation is available through the Microsoft Trust Center.
Customers are notified of new or replacement subprocessors in advance, with the opportunity to object as set out in the Data Processing Addendum. To subscribe to subprocessor-change notifications, email privacy@b5secure.com.
