Security built for healthcare.
Aria handles protected health information for thousands of dental patients every day. Here's exactly how we protect it — and what we expect of every vendor in our chain.
Compliance & certifications
Aria is built to operate as a HIPAA Business Associate of dental practices. We maintain a written compliance posture covering the HIPAA Privacy Rule, Security Rule, and Breach Notification Rule, plus HITECH alignment for breach response and electronic transmission of PHI.
Encryption
All protected health information is encrypted both at rest and in transit. We do not store PHI in plaintext anywhere in the system — including logs, error monitoring, and analytics pipelines.
At rest: AES-256-GCM
PHI fields encrypted with AES-256-GCM via authenticated encryption (master key 64-char hex, stored in cloud KMS, never in application code).
In transit: TLS 1.3
All API traffic, voice streams, and SMS gateway connections require TLS 1.3 minimum. TLS 1.0/1.1 explicitly disabled. HSTS enforced at the edge.
Key rotation
Default 90-day rotation policy on application-layer encryption keys. Cloud KMS-managed root keys rotated annually with cryptographic envelope re-keying.
Phone hash lookups
Patient phone-number lookups use SHA-256 hashing — we don't store decryptable phone numbers in lookup indexes. Original encrypted phone available only when an authorized session decrypts it.
Business Associate Agreement (BAA) process
Every Aria customer signs a BAA before any PHI is transmitted to the platform. Our BAA covers: permitted uses and disclosures, safeguards, reporting of breaches and security incidents, subcontractor flow-down, return/destruction of PHI on termination, and your audit rights as a covered entity.
To request the BAA before you sign, email AriaDental@Velzyx.ai. Standard turnaround is one business day. We will negotiate reasonable customer markups; we will not strip the standard breach-notification or audit-rights clauses.
Subprocessors
Aria uses a small set of vetted subprocessors. Each holds its own BAA with us where PHI may flow, and each holds compliance attestations relevant to its role.
Full subprocessor list with categories, purposes, and data types is available to customers and prospects under NDA — request from AriaDental@Velzyx.ai.
Access controls
Aria operates on the principle of least privilege. Every authenticated session — whether human admin, API client, or background worker — operates with the minimum permissions required for the task.
- Role-based access control (RBAC) across the admin dashboard. Owner, Manager, Front Desk, Provider, Auditor — each with distinct read/write scopes.
- Two-factor authentication mandatory for all admin and Aria-internal accounts. TOTP and WebAuthn supported; SMS 2FA deprecated for internal use.
- API key authorization with per-key scopes and rate limits. Keys rotatable by the practice owner without Aria intervention.
- JWT session tokens with short TTL and refresh-token rotation.
- Full audit logging of every data access event, including read-only views of PHI. Logs retained 12 months minimum, available to the practice on request.
- Privileged access review quarterly. Aria-internal staff who have admin-tier access to customer data is documented, reviewed, and minimized.
Data retention
Default retention policies, configurable per practice within regulatory bounds:
Breach notification
Aria operates a breach notification protocol aligned with the HIPAA Breach Notification Rule and HITECH:
- Internal target: 72 hours from detection — preliminary notification to affected practice contacts within 72 hours of confirmed unauthorized access or disclosure of PHI.
- Regulatory ceiling: 60 days from discovery — formal HIPAA-compliant notification with the standard required content (description of breach, types of PHI involved, steps to mitigate, contact information).
- Post-incident report — full root cause analysis delivered to affected practices within 30 days of notification.
- Coordinated regulator engagement — Aria coordinates with the practice on HHS OCR notification and any state attorney general notifications required.
- NIST Cybersecurity Framework alignment — incident classification and response phases mapped to the NIST CSF Identify/Protect/Detect/Respond/Recover model.
Vulnerability management
Security is a continuous practice, not a checkbox. Aria's vulnerability management program operates across three layers:
- Quarterly external penetration testing by an independent third party. Findings tracked to closure with documented remediation timelines.
- Continuous dependency scanning via GitHub Dependabot + npm audit + pip-audit. Critical CVEs patched within 7 days; high within 30; medium within 90.
- Static code analysis on every pull request — secrets scanning, SAST (semgrep), and CI-blocking on critical findings.
- Bug bounty / responsible disclosure — researchers can report vulnerabilities to AriaDental@Velzyx.ai. Acknowledgement within 48 hours; severity triage within 5 business days; coordinated disclosure once patched.
Incident response
Aria maintains a written Incident Response Plan covering preparation, detection, containment, eradication, recovery, and post-incident review. Key components:
- Tabletop exercises twice annually — leadership rehearses likely incident scenarios (subprocessor breach, internal credential compromise, ransomware, malicious insider) and validates response steps.
- IR playbook — written runbooks for our top dozen incident types, with named on-call owners and escalation paths.
- Customer communication templates — pre-approved language for breach notification, status updates, and post-incident reports. Communication during an incident is the second-most-important thing after containment; we don't want to be drafting tone in a crisis.
- Forensics readiness — log retention, immutable audit trails, and tooling that lets us reconstruct event timelines for regulators and affected practices.
Questions?
Security questions, BAA requests, vendor questionnaires, and pen-test findings all route to AriaDental@Velzyx.ai. We respond within one business day.
