Box is approved for High Sensitivity content, with limited CUI and FOUO.

Special handling requirements exist for CUI and FOUO documents, and requires an External System Request (ESR).

  • Contact for directions on the process.
  • Contact for projects that may involve Personally Identifiable Information (PII), Protected Health Information (PHI), to determine if a new or updated Privacy Risk Assessment may be necessary, and for any privacy related questions.
