Legal Hold Management platforms automate the issuance, tracking, and compliance monitoring of litigation hold notices — ensuring that potentially relevant electronically stored information (ESI) is preserved when litigation or investigation is reasonably anticipated. Core capabilities include hold notice creation and distribution, custodian acknowledgment tracking, reminder and escalation automation, custodian interview management, hold release workflows, compliance dashboards and reporting, and audit trail documentation for defensibility. The category spans dedicated legal hold platforms (Exterro, Zapproved/Exterro, Lighthouse) and hold management modules within broader eDiscovery and legal operations suites.
