1. An Information Handling System (IHS), comprising:
a processor; and
a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to:
transmit, from a workspace instantiated by a local management agent to a portal managed by an enterprise: (i) a request to store a once-encrypted document, and (ii) an indication that the once-encrypted document is encrypted with a controlvault key;
receive, from the portal at the workspace, a request to encrypt the once-encrypted document with an enterprise-issued cryptographic key to produce a twice-encrypted document;
encrypt, by the workspace, the once-encrypted document with the enterprise-issued cryptographic key to produce the twice-encrypted document; and
transmit, from the workspace to the portal, a copy of the twice-encrypted document.
