Preserve Collaboration Data Confidently with a Single, Defensible Workflow
When litigation or an investigation arises, you need confidence that the right data is protected. Onna’s in-place preservation secures custodian data across your entire tech stack with a single action before it can be deleted, edited, or lost.
Manual Preservation Workflows Leave Your Data Exposed
Legal and IT teams already know how complex it is to collect data across dozens of collaboration apps. Slack, Google Workspace, Microsoft 365, and other apps have transformed how work gets done, but they’ve also made preserving data that much harder. Teams struggle with:
- Preserving the right data across dozens of collaboration apps
- Relying on IT ticketing workflows to manually collect data from each individual app
- Lacking a defensible audit trail, leaving every preservation vulnerable to spoliation
- Starting every matter from scratch with no repeatable preservation workflow

Preservation FAQs
In-place preservation means Onna secures targeted data directly within the source system — preventing it from being deleted or edited — without moving or copying it. This keeps data secure and defensible while your normal retention policies continue to apply to everything outside the preservation scope.
Onna currently supports in-place preservation for Slack Enterprise, Google Workspace, Microsoft Teams Enterprise, and Quip Enterprise. For other sources, Onna’s Source Hold feature provides a comparable level of protection.
Onna supports up to 10,000 custodians per preservation. You can add individuals by name or email, upload a CSV list, or select “Everyone” to preserve all identities within a source.

Every preservation action — creation, edit, export, and deletion — is captured in a comprehensive audit log. Onna’s in-place preservation prevents data from being altered or deleted during the preservation period, giving legal teams a verifiable chain of custody.
No. Legal teams with the appropriate permissions can create and manage preservations directly within Onna, without opening an IT ticket. This eliminates days of lag time and gives legal the control they need to respond immediately to new matters.
When a matter concludes, you can release the hold, which releases the data back to the source while keeping the preservation record in Onna for reference. Alternatively, you can delete the preservation entirely, which removes both the hold and the entry from the interface.
Yes. From within any hold, you can search across the entire preservation or within individual sources. This allows you to quickly assess what data exists before deciding on next steps for collection or review.
By preserving only the custodians and date ranges relevant to your matter, Onna helps you avoid over-preservation — which reduces the volume of data sent to review platforms. Teams using Onna have reduced collection costs by 25% and review costs by 40%.
