Onna review
A focused choice for preservation, collection, and targeted culling across business applications.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Onna is a vendor-cloud data collection and management platform for legal, compliance, and IT teams. It connects collaboration tools, cloud storage, and business applications to preserve, index, search, filter, cull, and export unstructured data for eDiscovery, investigations, and compliance workflows. Its supported ecosystem includes Slack, Microsoft Teams, Microsoft Outlook, Google Workspace, Zoom, Box, Dropbox, Microsoft OneDrive, SharePoint, Amazon S3, Jira, Confluence, Salesforce, Zendesk, and GitHub. A REST-based Platform API supports custom data ingestion, while the deployment options are web and API.
The product’s strongest fit is the early and middle portion of an eDiscovery workflow. In-place preservation and legal holds help maintain data within connected applications, while real-time indexing and unified search provide a central way to locate relevant material. Filters for custodian, date, keyword, channel, and file type support targeted collection, and audit logs plus chain-of-custody records provide documentation around the process. Targeted culling can reduce the material sent downstream, with review-ready exports to Reveal, Logikcull, and other review platforms.
Onna uses contact-sales pricing. Published plan details state that pricing is based on processed and stored data, starts at 1 TB, and requires a sales conversation. The platform is suited to teams that need broad application coverage, preservation controls, defensible records, and focused exports before review. Teams seeking redaction, production, or AI capabilities within the same product should consider a broader platform or pair Onna with downstream tools that cover those stages.
