Comma Compliance

Encrypted messaging

Your team uses Signal for privacy. Regulators still want the records.

Full Signal functionality. No workarounds.

Signal conversations between your team and clients are business records under SEC Rule 17a-4 and FINRA Reg S-P. Comma captures them at point of delivery — open-source code, no device installation, no changes to how Signal works — and stores everything in tamper-proof, exam-ready archives.

Why Comma Works for Signal

For your compliance team

  • NLP supervision

    Comma's AI engine prioritizes critical messages, slashes false positives, and reduces analyst fatigue. We let humans call the shots, not algorithms alone.

  • Offline resilience

    If a phone goes offline, Comma still receives the message. Nothing slips through.

  • Regulator-ready storage

    Messages go directly to immutable archives that support SEC Rule 17a-4, FINRA Reg S-P, and more. Archived threads cannot be deleted.

For your IT team

  • Open-source connectors

    Inspect every step. Our Signal capture path is public, peer-reviewed, and available to audit or self-host.

  • Zero-exposure architecture

    Comma captures messages from the Signal network. No unencrypted data on phones, no saved private keys, no unprotected credentials on the device.

For your employees

  • No local footprint

    Our compliance software doesn't run on your employees' phones. Zero battery drain and no privacy concerns.

  • True-to-Signal experience

    We don't block, intercept, or degrade Signal functionality. Your team uses it as intended.

FAQ about Signal Compliance Archiving

Why is Signal harder to archive than email or Slack?
Signal was designed specifically to prevent third parties from accessing message content. Unlike Slack or Microsoft Teams, there is no admin API, no export tool, and no compliance integration built into the platform. Archiving has to happen at the device or account level — and most approaches either modify the app (introducing security risk) or rely on screen capture (which breaks encryption guarantees). Comma captures Signal as an authorized linked device, the same way a second phone would receive messages.
Does Signal have a compliance API?
No. Signal does not offer an archiving API, a compliance export feature, or an enterprise admin console. Platforms like Slack and Teams provide official compliance integrations. Signal does not. Any vendor claiming Signal archiving is doing it through a method outside of an official API — understanding that method is the due diligence question.
Does Comma break Signal's end-to-end encryption?
No. Comma captures messages as an authorized endpoint — the same way a linked device receives them. The message arrives encrypted and is written to tamper-proof storage without being decrypted on an intermediate server. This is different from approaches like TeleMessage, which decrypted messages on an intermediary before archiving them.
What happened with TeleMessage and Signal?
In May 2025, TeleMessage — a compliance archiving vendor acquired by Smarsh in 2024 — was breached. Their Signal archiving worked by modifying the Signal app to decrypt messages on an intermediate server. A hacker accessed a debug endpoint on that server and extracted plaintext chat logs in roughly 15 minutes. Signal's own statement noted it could not guarantee the security of unofficial versions of its app. Comma's Signal connector is published on GitHub and does not use a modified app or intermediate decryption.
What about Signal's disappearing messages feature?
If disappearing messages are enabled on a conversation, Comma captures the message at delivery before it disappears from the device. The archive record is unaffected by the disappearing message timer.
Does Signal compliance work on both iOS and Android?
Yes. Comma captures Signal messages across iOS, Android, and desktop — without installing anything on the employee's device.

Signal doesn't prevent compliance.

It just requires a smarter solution.
