Supervision is the systematic review of archived communications against policies and lexicons to detect misconduct, conflicts of interest, or regulatory breaches. FINRA and SEC rules require certain firms to supervise employees' business communications.

Personally Identifiable Information (PII) is data that can identify an individual; Protected Health Information (PHI) is health data tied to an individual under HIPAA. Archives detect and govern PII/PHI to apply the right security, retention, and privacy controls.
