Zapproved
Zapproved is an ediscovery and legal hold platform built for corporate legal departments, acquired by Exterro in January 2023 and sold as ZDiscovery within the Exterro Legal GRC suite. It automates hold notices and custodian reminders, in-place preservation across Microsoft 365, Google Vault and Slack, targeted collection from Office 365, and Nuix-powered processing with deduplication, search, tagging and redaction. In-house teams use it to keep preservation defensible, cut data volumes before review, and reduce dependence on IT and vendors.
About the product
Zapproved is a corporate ediscovery software company founded in 2008 and acquired by Exterro in January 2023, where the ZDiscovery platform it launched in 2021 is now sold inside the Exterro Legal GRC portfolio. It was built specifically for in-house legal teams that must issue litigation holds, preserve and collect data, and review documents without routing every step through outside vendors.
Key features of Zapproved include:
- Legal Hold Management: Creates, distributes, and monitors hold notices with automated custodian reminders, acknowledgement tracking, and audit trails that support defensibility in court.
- In-Place Data Preservation: Preserves custodian data directly in Microsoft 365, Google Vault, and Slack without IT involvement, recording an automated audit record of every preservation action.
- Targeted Data Collection: Collects from Office 365 sources including Teams chats using certificate-based authentication, targeted search criteria, and real-time collection status monitoring.
- Processing & Culling: Runs the Nuix processing engine across file types and applies deNISTing and deduplication to cut data volume before review or transfer to outside counsel.
- Review & Production: Supports keyword search, tagging, redaction, and multi-format export so routine matters can be reviewed and produced entirely in house.
Best for: Corporate legal and litigation teams at mid-market and enterprise companies that need defensible legal hold, preservation, and in-house review across high-volume matters.
The platform keeps ediscovery under corporate legal control from the moment litigation is anticipated through production, lowering outside counsel and vendor spend while reducing the risk of spoliation sanctions.
Zapproved is a corporate ediscovery and legal hold platform, now part of Exterro and sold as ZDiscovery, that automates litigation holds, preservation, collection, and review.
