Map the data journey
Identify where messages enter, are stored and can be read, including downstream tools. An open model may run locally or through a hosted service. The label does not establish where processing occurs.
Minimize exposure
Use internal identifiers when full identity is unnecessary. Redact secrets from logs and limit support access. Define purpose-based retention and test deletion across dependent systems, not just removal from the interface.
Verify isolation
Test two customer organizations and a user whose access is revoked mid-session. Ensure retrieval respects current permissions. Have the responsible specialist assess applicable contractual and privacy requirements; design checks do not replace that review.
