## Real-time Signal capture

Comma captures Signal messages as they're delivered, with no on-device software or MDM, no battery drain, and no third-party tools.

Signal capture is included in Comma's flat $33/user/month. No add-on, no surcharge, no metered usage. [See pricing](/pricing).

Setup takes one step. Your employee scans a QR code from the Comma dashboard. From that point, every encrypted business Signal message is captured and stored automatically.

**We work the way Signal works:**

- No decrypted local data
- Fully inspectable capture. [Source code on GitHub](https://github.com/comma-compliance/signal-capture)
- No changes to how your team communicates

## How to Archive Signal Messages for FINRA Compliance

FINRA Rule 4511 and SEC Rule 17a-4 require firms to retain business communications, including Signal messages, and make them available for exam. That obligation applies regardless of whether Signal is officially approved or used informally. Firms need a capture solution, a retention policy, and a supervision workflow.

During a FINRA exam, regulators typically request records in a specific date range or involving a specific individual, and expect the firm to produce complete conversation threads, with timestamps and participant details intact, within a short turnaround window.
