Voice AI Security & Compliance: SOC 2, GDPR, HIPAA in Plain English

Voice AI handles conversations, and conversations can contain personal data. That puts security and compliance at the centre of any serious deployment. Here's what the acronyms actually require — in plain language — and what to demand from a vendor.

The four questions behind every framework

1. Who can access the data? Access controls, SSO, and role-based permissions.
2. How is it protected? Encryption in transit and at rest, and tenant isolation.
3. How long is it kept? Configurable retention and reliable deletion.
4. Can you prove it? Audit trails and independent certification.

SOC 2 and ISO 27001

These are about how the vendor runs its security program: documented controls, monitoring, incident response, and regular independent audits. They don't guarantee any single feature, but they tell you the organisation takes security seriously and is checked by a third party. Ask for current reports.

GDPR (and friends)

GDPR is about respecting people's rights over their data: lawful basis, data minimisation, the right to access and deletion, and not moving data somewhere it shouldn't go. For voice AI, that means capturing only what's needed, retaining it only as long as useful, and supporting deletion requests. Regional residency options matter for sovereignty.

HIPAA

If you're in US healthcare, HIPAA governs protected health information. A HIPAA-ready vendor will sign a Business Associate Agreement, isolate and encrypt data, limit access, and log everything. "HIPAA-ready" should come with specifics, not just a logo.

Compliance is not a feature you switch on — it's a posture you verify. Logos are a starting point; reports, BAAs, and architecture answers are the proof.

Voice-specific concerns

• Recordings. Are audio and transcripts stored? Where, and for how long? Can you turn storage off?
• Presence sensing. Is anything biometric captured, or only presence? (It should be only presence.)
• Grounding data. Does your knowledge base stay within your boundary?
• Sub-processors. Who else touches the data, and under what terms?

A practical checklist

Get current SOC 2 / ISO reports, a data-flow diagram, the retention settings, the sub-processor list, and — if relevant — a BAA. If a vendor can't produce these quickly, treat it as a finding.
