WhatsApp Compliance Archiving for SEC and FINRA-Regulated Firms

FINRA and the SEC have made off-channel messaging a top examination priority. WhatsApp conversations between your team and clients are business records. Comma captures them automatically at the linked-device level, in real time, with zero IT overhead. Everything is stored in WORM-compliant archives and searchable the moment a regulator asks.

Get in Touch

WhatsApp is how your clients communicate. Your solution should capture it.

Comma captures every business WhatsApp conversation in full, including messages, attachments, timestamps, and thread structure, while keeping personal content separate. Employees keep using WhatsApp exactly as they do today. Capture happens off-device, so there is nothing to install and no change to how your team works.

What gets captured - and what doesn’t

Comma captures business conversations from WhatsApp in full. Here is exactly what is in scope.

  • WhatsApp business messages, captured at the source

    • 1:1 and group chats, no matter the device
    • Works with personal or corporate WhatsApp accounts
    • What we don't store: messages from personal contacts

  • Message details, fully preserved

    • Timestamps and contact data included
    • Attachments (images, PDFs, audio) auto-captured
    • Thread structure and message order retained for clarity

  • Cross-device compliance, built in

    • Conversations from phones, desktops, and web versions
    • Auto-archived to tamper-protected, exam-ready storage
    • SEC and FINRA retention requirements fully supported

  • Connector source code available

    • Inspect every line of our WhatsApp capture on GitHub, with complete code access and zero vendor lock-in. See the code →

Every archived conversation is stored with full thread context, participant details, and timestamps, exactly as it was sent.

How to Archive WhatsApp Messages for Financial Services Firms

Archiving WhatsApp messages for financial services requires more than saving chat logs. SEC Rule 17a-4 and FINRA Rule 4511 require that records be captured in real time, stored in tamper-protected WORM-compliant storage, and retrievable on demand — including messages from personal WhatsApp accounts used for business.

The WhatsApp challenge is capturing everything — the archive piece is the easy part. Manual exports miss messages. Modified apps break end-to-end encryption, exposing client communications to third-party intermediaries. Backup-based solutions leave gaps when backups are delayed, disabled, or deleted.

The result: a complete, audit-ready archive of WhatsApp messages for financial services use — without changing how employees communicate.

WhatsApp is now a top examination priority.

SEC Rule 17a-4 and FINRA Reg S-P require firms to capture and retain off-channel communications, including WhatsApp.

Regulators aren't asking whether your team uses it. They're asking whether you have the records.

What Does a Capture Failure Actually Cost?

Regulators aren’t speculating about whether WhatsApp is being used for securities business. They’ve seen the messages. And the fines reflect it.

The enforcement wave started with household names. In 2021, JPMorgan paid $125 million after the SEC found firm-wide use of WhatsApp across three years — including by managing directors — that actively hindered multiple investigations. By 2022, Goldman Sachs and Morgan Stanley each paid $200 million for the same category of violation.

Then it spread. In August 2024, the SEC fined 26 firms a combined $392 million in a single action — including Ameriprise, LPL Financial, Raymond James, and Edward Jones, each paying $50 million. Fiscal year 2024 ended with over $600 million in off-channel penalties against more than 70 firms.

The violations aren’t slowing down. In January 2025, KKR, Charles Schwab, Apollo, and Carlyle were among 12 firms paying $63 million in the latest round.

Individual representatives face consequences too. In May 2024, FINRA accepted an AWC against a registered rep — a 6-month suspension and $15,000 fine after he used WhatsApp to authorize trades with six clients on a channel his firm never captured, and falsely attested he wasn’t doing it.

The compliance gap wasn’t a policy failure. It was a capture failure. Comma closes it automatically — archiving every business conversation from WhatsApp the moment it happens, without changing how your team communicates.

Why the architecture matters

For your compliance team

  • AI-assisted review

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

  • Continuous capture

    Messages archived in real time, even across device switches.

  • Regulator-ready storage

    Designed against SEC Rule 17a-4 and FINRA Reg S-P. Immutable, tamper-protected archives.

For your IT team

  • Centralized deployment, any scale

    Deploy across your full user population from one admin console. No MDM enrollment, no per-device software, no branch IT engagement. The same architecture handles 10 registered representatives or 500 — no additional infrastructure required. Supports holding company structures — deploy once, cover all subsidiary broker-dealers from a single console.

  • No endpoint management

    Comma captures from the network layer. Nothing runs on employee phones — no app to push, no profile to maintain, no update cycle to manage.

For your employees

  • Off-device architecture

    Comma doesn't run on employees' devices. No battery drain, no device enrollment, no local footprint.

  • True-to-WhatsApp experience

    No blocking, interception, or UX changes. They use WhatsApp, and Comma captures it.

FAQ about WhatsApp Compliance Archiving

Does it matter whether employees use personal or business WhatsApp?
No. Comma captures business communications from both personal WhatsApp accounts and WhatsApp Business accounts. The regulatory obligation follows the communication, not the account type. If a client conversation happened on personal WhatsApp, that record is still subject to SEC Rule 17a-4 and FINRA 4511.
Why not use the WhatsApp Business API for compliance archiving?
The WhatsApp Business API is built for outbound customer messaging at scale, like automated notifications and support queues. It doesn't see the conversations that create compliance risk: personal WhatsApp chats and employee-to-client group threads. Comma takes a different route. It captures at the account level as an authorized linked device, which covers both personal and WhatsApp Business accounts across 1:1 and group chats. That's the off-channel activity the Business API leaves out.
Does Comma require installing anything on the employee's phone?
No. Comma does not run on employee devices, requires no app installation, and has no MDM requirement. Archiving happens off-device, which means no battery drain, no local footprint, and no change to the employee's WhatsApp experience.
What is the difference between Comma's approach and TeleMessage's?
TeleMessage used a modified version of WhatsApp that decrypted messages on an intermediate server before writing them to an archive. That intermediate decryption created the attack surface that was exploited in the May 2025 breach. Comma captures messages as an authorized linked device — the same way any connected device receives them — without modifying the app or holding plaintext on intermediary infrastructure. The capture code is published on GitHub for independent verification.
Does Comma capture WhatsApp group chats?
Yes. Group chats, 1:1 conversations, attachments, and reactions are all captured. Thread structure and message order are preserved for examination readiness.
How long do firms need to retain WhatsApp communications?
Under SEC Rule 17a-4 and FINRA Rule 4511, broker-dealers must retain business communications for a minimum of 3 years in an accessible format, with a total retention period of 6 years. Storage must be immutable — either WORM-compliant or backed by a full audit trail that prevents alteration or deletion. Comma captures messages at the point of delivery and writes them immediately to immutable, write-once storage, so records are preserved from the first message.
What if an employee tries to delete a WhatsApp message?
Messages are captured and written to WORM-compliant storage at the point of delivery. A deletion on the custodian's device after that has no effect on the archived record.
Can Comma ingest our existing WhatsApp archive?
Yes, if your firm has existing export files or prior archive data, Comma can ingest them. The important caveat: historical data reflects what was stored at the time of export. Any messages deleted or edited on employees' devices before that export cannot be recovered, and Comma cannot attest to the completeness of a dataset it did not capture live. For records going forward, Comma captures at point of delivery, which eliminates this gap entirely.
How do I prepare for a FINRA or SEC exam of my WhatsApp archiving?
Examiners check WSPs, supervision records, archive readiness, and your ability to produce records on demand. See the [exam-ready checklist](/regulations/exam-ready-checklist) for a full rundown of what to have ready.

WhatsApp is business-critical. Your archive should be too.
