“I think of Onna like insurance… if something goes wrong it’s going to reduce your exposure dramatically.”

Pra Chandrasoma
General Counsel

We wanted to have confidence that the data we’re preserving and storing is not at risk of accidental deletion or spoliation… That’s where we’re seeing the value — ensuring we’re not going to get in trouble when it comes to any of this data.”

Dylan Tonti

FAQs

When should I choose Onna over Theta Lake?

When your primary need is broad data collection and eDiscovery across the modern collaboration stack, not just voice, video, and chat. Onna’s 29+ no-code connectors cover Slack, Microsoft 365, Google Workspace, Box, Dropbox, Atlassian, GitHub, Salesforce, ChatGPT, Gemini, Miro, and more, with native eDiscovery workflows for legal hold, ECA, defensible collection, and review-ready export.

When does Theta Lake still have the edge?

Unified communications compliance in regulated industries (SEC, FINRA, MiFID II, CFTC, IIROC). Theta Lake’s 100+ UC integrations and AI-driven non-text risk detection are suitable for voice, video, screen-share, and chat compliance. Some regulated customers run both products side-by-side.

How does Onna handle review and production?

Onna is natively integrated with Logikcull. Collect with Onna, then move straight into Logikcull for review, redaction, and production.

How does Onna get teams up to speed quickly?

Onna’s pre-built, no-code connectors require less than a half day of effort from a single IT resource. Initial setup and first collection complete within one business day, ~80% less time than the average collection.

How does Onna keep collections defensible?

Comprehensive audit logs; native in-place preservation for Slack, Google Workspace, and Quip; Microsoft 365 in-place preservation via Reveal Hold; near-native rendering of threads, edits, and reactions; role-based access controls; and WORM storage. Onna is ISO 27001, SOC 2 Type II, and HIPAA certified.

Can Onna and Theta Lake be used together?

Yes, they can. Regulated-industry customers can keep Theta Lake for unified communications compliance (voice/video/chat supervision and archiving) and add Onna for broader eDiscovery and information governance across the rest of their data estate.

eDiscovery and information governance across the full collaboration stack.
