D-KaP SMS — the EpochCore product that turns every business text between your reps and clients into a tamper-evident communication record — captures who texted whom, when, and a one-way fingerprint of the message content. FINRA Rule 3110 communication evidence without trusting your carrier or text-archiving vendor.
Off-channel communications — reps texting clients from personal devices — have generated more than $2 billion in SEC and FINRA fines in the last three years. Your firm has a text-archiving solution (Smarsh, Global Relay, MirrorWeb). It captures the messages. But your examiner is asking a sharper question: how do you know the text history you exported today matches what was actually sent? Vendor archives can be re-indexed. Records can be soft-deleted. A screenshot is not evidence.
SMS sits next to your existing text-archiving system. Every time a business text is captured (by your carrier, MDM, or archive vendor), you POST the metadata (sender, recipient, timestamp, message ID) plus a one-way fingerprint of the message content to a single endpoint. The service seals that record with a tamper-evident signature and timestamp. The message body stays in your archive; only the fingerprint goes to us. Months or years later your examiner asks for a specific conversation — you hand them the messages, the sealed receipts, and a verifier. They confirm in seconds that the text history they are reading is byte-for-byte the same content sent at the time, and that the receipts have not been touched since.
Add a webhook from your text-archiving tool (Smarsh, Global Relay, MirrorWeb, Twilio Conversations) that fires on each captured message. The webhook POSTs metadata and the content fingerprint to our endpoint.
The endpoint returns a sealed receipt within seconds. Store it next to the message in your archive (S3, vendor portal, or compliance data warehouse).
When FINRA or the SEC asks for a specific text history, export the messages plus the sealed receipts. The examiner runs the open verifier — the receipt signatures hold and the content fingerprints match. Investigation moves on.
Example: A wealth-management firm's rep texts a high-net-worth client about an upcoming private placement. Two years later the client claims the rep promised a specific return in writing. The CCO produces the full text thread from the archive plus the SMS receipts sealed at the time. The arbitrator runs the open verifier — signatures hold, content fingerprints match. The actual words sent become the question, not whether the texts are real. The CCO closed the issue in one meeting instead of three depositions.
SEC and FINRA off-channel-communication fines have ranged from $750,000 for small firms to over $200 million for the largest. The findings that drive those fines are almost always about the integrity and completeness of the archive, not the texts themselves. One $29 seal per text removes the integrity question. For a firm sending 1,000 business texts a week, the cost is a rounding error against a single deferred fine.
Adds an invisible stealth watermark keyed to your firm on the exported receipt. The watermark survived 90 of 136 measured attack vectors in our test matrix at SSIM 0.985 (visually identical to the original) with zero false-positive matches. Stays attached through screenshots and re-uploads. If a receipt ever leaks or surfaces in another proceeding, you have a machine-readable trace back to your firm. Not "uncopyable" — a determined attacker can still scrub it — but tamper-evident in the ways FINRA, the SEC, and arbitration counsel actually care about. MEASURED
