In one embodiment, a device may obtain an identifier of a proof of location process (PLP) and an identifier of a node where the PLP is executed. The device may receive a query from a compliance engine for a proof of location of the node where the PLP is executed. The device may identify, based on the identifier of the PLP and the identifier of the node, a physical location of the node. The device may provide, to the compliance engine, a response to the query that is indicative of the physical location of the node, wherein the compliance engine enforces one or more data compliance policies with respect to a workload executed by the node and based on the physical location of the node.
