Theta Lake is a unified communications compliance platform built around enterprise collaboration tools.
For most financial firms, the compliance gap isn’t Webex recordings or Cisco integrations. It’s mobile - texting, iMessages, WeChat - the channels your team is already using with clients, right now, without a capture solution in place.
This comparison breaks down Comma Compliance vs. Theta Lake on the metrics that matter most: capture coverage, security, pricing, and regulatory exam readiness — helping you find the right compliance archiving solution for your firm.
At a Glance
Theta Lake is strong for Unified Communications and Collaboration (UCC) tools.
Mobile consumer messaging is a different story. WhatsApp, Signal, and iMessage capture routes through third-party partners (LeapXpert, Movius, CellTrust), not Theta Lake’s own capture layer. If your examination risk lives in encrypted consumer messaging apps — not just recorded meetings — that distinction matters.

| Mobile capture method | Native — no third-party mobile partner required | Partner-dependent — routes through LeapXpert, Movius, or CellTrust |
| WORM storage | Yes | Yes |
| iMessage capture method | Point-of-delivery — not iCloud-dependent | Not documented in mobile capture materials |
| WhatsApp capture | Captures both WhatsApp Business and personal WhatsApp | Via partner integrations (LeapXpert, Movius, CellTrust) |
| Signal capture | Yes — open-source capture code published on GitHub | Via LeapXpert integration |
| Channels supported | 35+ channels where conversations happen: iMessage, WhatsApp, Signal, SMS, Voice, Microsoft 365, Teams, Exchange, OneDrive, Gmail, Google Workspace, Slack, Zoom, Webex, Bloomberg Chat, Salesforce, Telegram, and more. | 100+ integrations across UCC, voice, video, email, social, financial messaging |
| Pricing model | Flat monthly pricing, all platforms included. No per-connector fees, no storage overages, no export fees. $33/user active, $15/user archival. | Not publicly listed; tier and feature-set based; annual or multi-year |
| Free trial | Yes | Not publicly offered |
| Personal vs. business separation | Automatic contact-based filtering — personal contacts can be excluded automatically | Dependent on mobile partner (e.g., Movius provides second business line) |
| Custom policy matching | Yes | Yes |
| Case management | Exam-ready — built for regulatory examination prep | Oriented toward litigation |

When Theta Lake may be a better fit
- Firms whose compliance risk lives entirely in recorded enterprise meetings
- Firms where employees do not use WhatsApp, Signal, Wechat, or iMessage for business communications
Partner Dependency
Mobile consumer messaging is different from recorded meetings. WhatsApp, Signal, and iMessage operate outside the collaboration stack, outside IT control, and outside the reach of Theta Lake’s native capture layer. To cover those channels, Theta Lake relies on third-party mobile compliance partners: LeapXpert, Movius, and CellTrust. WhatsApp and Signal capture isn’t run by Theta Lake; it runs through a partner’s system. The capture method, data handling, and reliability are subject to the partner’s architecture, not Theta Lake’s.
iMessage
Theta Lake’s mobile capture documentation does not address iMessage. Comma’s iMessage capture happens at the point of delivery, independent of iCloud. If the message is delivered, it’s captured. No iCloud backup dependency, no sync window, no failure if a device is offline.
Due Diligence
Questions to Ask Any Compliance Vendor
- 01
Where exactly is the message first captured - at the point of delivery, or after a backup or sync cycle?
- 02
What conditions must be true for a message to be captured? What happens if any of those conditions aren't met?
- 03
If a user edits or deletes a message before capture occurs, what version gets archived?
- 04
Can you show documentation - architecture diagrams, code, or an independent audit - of how your capture actually works?
- 05
Where are encryption keys stored, and who controls them?
- 06
Are all channels included in the base price, or are there per-connector fees?
- 07
Are there export or egress fees?
- 08
Does your case management workflow support regulatory examination prep?
- 09
Can cases be opened directly from flagged message threads?
- 10
Is any client data used to train your models? Under what conditions?
- 11
Can we adjust, refine, or contribute feedback to my policy models? (e.g., different languages, customer-complaint responses)
