Microsoft Purview eDiscovery vs Relativity Legal Hold

Microsoft Purview eDiscovery has no write-up on Specifiction yet; its figures are above.

Relativity Legal Hold helps organizations identify and preserve relevant data when litigation is expected. It sends hold notices, interviews custodians, follows up with people who have not responded, and tracks their replies. Reports can document communications with custodians and other relevant parties. The product preserves data in place from major productivity platforms in a secure Azure environment, with Microsoft 365, Google Vault, and Slack listed as integrations. A setup wizard assists with choosing custodians and data sources, and the service provides workflow updates and error alerts. Relativity says analytics and scoping criteria can reduce data volume by up to 80%. Preserved data can move to RelativityOne for review through Collect as a matter or investigation proceeds. Legal Hold runs in Relativity workspaces; full use requires setup of access, email, the custodian portal, and preservation settings. Pricing is provided on request, and the product is licensed separately from the data volume commitment. It is available via web and API.
