The AI transaction coordinator security stack for 2026: GDPR-ready data processing, TCPA-compliant voice/SMS, encryption in transit and at rest, sub-processor disclosure, and a broker-of-record audit portal.
The Four Compliance Layers
(1) GDPR — data subject rights, DPA, sub-processor disclosure. (2) TCPA — opt-in capture, opt-out honored, recordkeeping for voice/SMS. (3) State privacy laws (CCPA, VCDPA, CPA, others). (4) Encryption — TLS 1.3 in transit, AES-256 at rest.
Why This Matters for Brokers
Brokers face vicarious liability for any data breach involving client information. State real estate commissions audit data-handling. CFPB scrutinizes wire-fraud-related practices. Brokerages selecting AI TC software in 2026 are selecting their compliance posture.

Frequently Asked Questions
How does TCPA compliance work for AI voice agents?
The brokerage must capture documented consent before any automated voice or SMS contact. Consent must be specific to the channel and the party. Opt-out must be honored immediately and recorded. ReBillion captures consent at file open and respects opt-outs across files.
What is a sub-processor and why does it matter?
A sub-processor is a third party the vendor uses to process client data (e.g., Twilio for voice, AWS for hosting). GDPR requires disclosure and DPA pass-through. ReBillion publishes a sub-processor list and notifies before adding new ones.
How is wire-fraud risk mitigated by the security stack?
Verbal verification of wire instructions (workflow guardrail), encryption of all stored wire instructions, and audit trail of every email containing wire data. The security stack supports the workflow; it does not replace it.
Is ReBillion SOC 2 compliant?
SOC 2 is planned.
Does ReBillion publish security documentation?
Planned on the roadmap: a public sub-processor list, a public DPA template, and public privacy policy and TCPA disclosures.
