Systems and methods can allow for secure cross-device sharing of transient data using direct transient data sharing (“DTDS”). A source destination can share data using local DTDS with an agent on a first device. The agent can send the data to a hub server that runs a security control process and data formatting process. The hub server can determine risk scores for the source and destination devices and allow the sharing to occur if a safety threshold is met. Then an agent on the destination device can receive the transient data and use local DTDS to send the data to a destination application.
