Find the Evidence. Cut the Outside Counsel Costs.
When litigation or an investigation hits, in-house legal needs to move fast to preserve the right data, surface the communications that matter, and control outside counsel costs. Onna delivers the speed, insight, and control to do all three.

From trigger event to "found it" in under a day
The moment litigation is reasonably anticipated or an investigation opens, the clock starts. In-house legal teams need to lock down data across collaboration apps including Slack, Google Workspace, Zoom, Microsoft 365, and more — without waiting on IT, outside counsel, or a vendor to spin up a process. With Onna, you can connect to all your data systems and start searching within a day, preserve data in place across key collaboration apps the moment a hold is applied to prevent deletion or editing, and search across collected data within minutes of preservation.
Every preservation, collection, and user action is automatically documented with audit logs, so your process is defensible from the start.

The Relevant Data Is There. Find It Before Anyone Else Does
Fast-moving investigations don’t wait for IT tickets or manual keyword searching. Whether it’s an executive misconduct matter, an HR escalation, or a regulatory inquiry, the communications that define the outcome are sitting somewhere across your collaboration apps. Early Case Assessment (ECA) starts the moment data is collected. In-house legal teams that can search and analyze data internally find what matters faster, and with more control over what gets escalated and what doesn’t. With Onna:
- Surface relevant communications across 29+ apps without logging into each system separately
- Get results in minutes, not days, with real-time indexing
- Cull targeted data and assess relevance before anything goes to outside counsel or a vendor — reducing data volumes by up to 70%+

Cut What Goes to Outside Counsel. And What It Costs.
Outside counsel and eDiscovery vendors charge by the gigabyte. When in-house legal teams can’t search and cull internally, everything goes out the door — relevant or not — and the review bill reflects it. Onna gives in-house legal the tools to make relevance decisions before data ever reaches a vendor, dramatically reducing the volume that drives outside costs. With Onna, you can:
- Search and cull internally before passing anything to outside counsel or review vendors
- Reduce data volumes sent for review by identifying and excluding clearly irrelevant material early
- Maintain control over what leaves the organization and when, with a full audit trail to back it up
Give In-House Legal the Speed, Insight, and Control to Own Every Matter
Find It First
Unified search across 29+ apps surfaces the communications that matter, before outside counsel or opposing parties get there first.
Cut Outside Costs
Search, cull, and assess relevance internally before anything reaches a vendor or law firm. Send less. Spend less.
Stay Defensible

“I think of Onna like I think of insurance: you buy it hoping you never need it but if something goes wrong it’s going to reduce your exposure dramatically.”

Setup and in-place preservation across systems can be completed within one business day. Once connected, Onna indexes collected data in real time, meaning your team can begin searching within minutes of the first collection, without waiting on IT, outside counsel, or a vendor to stand up a workflow.
Onna's unified search reaches across all connected apps simultaneously — Slack, Google Workspace, Microsoft 365, Zoom, and more — from a single interface. Targeted filters allow legal to search by custodian, date range, keyword, and data type, surfacing relevant communications without manually logging into each platform or waiting on IT to run separate queries.
Yes. Onna is built for legal and people operations teams to use independently. Once the initial connector setup is complete, in-house legal can apply preservation holds, run searches, and collect data without routing requests through IT on every matter.
Onna's in-place preservation locks targeted data — messages, files, and recordings —t he moment a hold is applied, preventing deletion or editing across all connected apps. Every preservation action is logged automatically, creating a documented, defensible record from the moment the trigger event occurs.
By enabling in-house teams to search, cull, and assess relevance before data ever leaves the organization, Onna dramatically reduces the volume sent to outside counsel and review vendors. Less data out the door means lower processing fees, smaller review populations, and significantly compressed outside spend on matters where internal teams can do the early work.
Every preservation, collection, search, and export generates a timestamped audit log with full user attribution. WORM storage ensures data immutability and a tamper-proof chain of custody. Complete audit trails are available for export and can be produced in response to court orders, regulatory inquiries, or opposing counsel requests.
Onna connects to 29+ apps including Slack, Google Workspace, Microsoft 365, Zoom, and Jira. If workplace communications are happening there, Onna can preserve, search, and collect from it. Check out our connectors page: Connectors | Onna
