SECURITY & GOVERNANCE
Built for organizations that take security seriously.
VAERION's governance architecture ensures every action is traceable, every agent is sandboxed, every decision is auditable, and every communication requires consent. This is not checkbox compliance — it is structural security built into every layer of the platform.
OUR APPROACH
Security is architecture, not configuration.
Most platforms bolt security on after the product is built. VAERION was designed from day one with default-deny access control, immutable audit logging, tenant isolation, and consent-gated execution. Security decisions are structural — they cannot be misconfigured, bypassed, or accidentally disabled.
ACCESS CONTROL
Default-deny. 27 permission categories. Zero world-readable endpoints.
Default-Deny RBAC
Every API endpoint requires explicit permission. Anonymous requests receive 401. Authenticated requests without the required permission receive 403. There are no world-readable endpoints — access must be granted, never assumed.
The permission system spans 27 categories covering every domain: CRM operations, communication dispatch, document management, workflow execution, autonomy control, governance administration, and more. Each user's access is the intersection of their role's permissions and their tenant's entitlements.
Role-Based Permission Model
Four standard roles (Admin, Operator, Analyst, Viewer) with the ability to create custom roles with granular permission selection. Permissions are additive — a user has exactly the permissions assigned to their role(s), nothing more.
Permission checks are enforced at the handler level, not the routing level. Even if a request reaches the correct endpoint, the handler verifies the caller's identity and permission before executing. This prevents authorization bypass through URL manipulation or request forgery.
Tenant Isolation
All data queries are scoped by tenant identifier at the database layer. Cross-tenant access returns empty results — it is structurally prevented, not just policy-gated. Your data never touches another organization's boundary, even in shared infrastructure.
This isolation applies to every table, every query, every API response. A compromised session token from one tenant cannot read, write, or enumerate data from another tenant. Tenant scoping is enforced by the query layer, not application logic.
Session & Authentication Security
Authentication uses secure, HTTP-only session cookies with SameSite protections. Admin operations require a separate, timing-safe API key comparison that prevents timing attacks. There is no identity header spoofing — session identity is derived exclusively from the authenticated cookie, never from request headers.
CI enforcement scripts verify that no code path accepts identity from headers without session validation, preventing the reintroduction of spoofing vulnerabilities.
AUDIT TRAIL
SHA-256 Merkle-chained event ledger.
Every action in VAERION produces an immutable, cryptographically linked audit record. The event ledger is not a simple log table — it is a hash chain where each entry's integrity is verifiable against all previous entries. Tampering with any record breaks the chain and is immediately detectable.
How the chain works
Append-only architecture
Events can only be appended — never modified, deleted, or reordered. The ledger is structurally immutable.
Hash linking
Each event includes the SHA-256 hash of the previous event. The chain is traversed structurally via hash links, not temporally via timestamps.
Tamper detection
A single modified record breaks every subsequent hash. Chain integrity verification walks the entire chain and detects any inconsistency.
Fork prevention
A unique constraint ensures one genesis event per tenant and prevents chain forks. The ledger is a single, linear, verifiable history.
What gets recorded
27 event types
Every category of platform activity: interactions, AI decisions, policy changes, governance actions, consent events, administrative operations, communication dispatches, and more.
Full actor attribution
Every event records who caused it (user, system, or API), the source module, and the full payload context. You can trace any decision back to its origin.
Allowed AND denied actions
The ledger records both successful operations and blocked attempts. You see not just what happened, but what was prevented and why.
Exportable for compliance
The full audit trail is queryable and exportable. Present it to a regulator, a board, or a compliance auditor with cryptographic proof of completeness.
COMMUNICATION GOVERNANCE
Consent-first. Fail-closed. Compliant by design.
VAERION's communication layer will not send a message without verified consent. This is not a configurable setting — it is a structural constraint. If consent is absent, revoked, or expired, the message is blocked. Period.
Per-Channel Consent
Consent is tracked per customer, per channel (SMS, email, voice), per purpose (transactional, marketing, support). Granting SMS consent for appointment reminders does not grant SMS consent for marketing. Each combination is independently managed and audited.
Quiet Hours & Frequency Caps
No messages are sent outside permitted windows (default: 8am–9pm local time, derived from area code). Per-customer frequency caps prevent over-messaging. These constraints are enforced at the dispatch layer — they cannot be bypassed by application code.
Regulatory Compliance
The consent engine is aware of TCPA (US SMS/voice), GDPR (EU email/data), CASL (Canadian commercial electronic messages), and HIPAA (healthcare communications). Compliance rules are applied automatically based on the customer's jurisdiction and the communication channel.
Fail-closed for healthcare
When a tenant has healthcare PHI controls enabled, VAERION's communication layer automatically blocks all non-BAA communication providers. Protected health information cannot be transmitted through standard messaging channels — regardless of configuration, user action, or application code. This is infrastructure-level enforcement, not a policy toggle.
AI GOVERNANCE
Four levels of autonomy. You control the dial.
Every AI action in VAERION passes through an autonomy gate before execution. The gate checks the current autonomy mode, the available budget, the applicable policy, and the required consent — all before a single action is taken.
MODE D
Hard Block
All AI execution disabled. View-only mode. No autonomous actions of any kind. Use during incidents, audits, or initial evaluation.
MODE C
Assist
AI drafts recommendations and suggests actions. Every action requires explicit human approval before execution. Full human control with intelligent suggestions.
MODE B
Supervised
AI executes within defined policy boundaries. Human oversight on exceptions and escalations. Budget-constrained and policy-governed. The most common production mode.
MODE A
Autonomous
AI operates independently within strict governance rails. Full audit trail on every action. Instant rollback available. Budget limits and policy constraints remain active.
Kill Switch
Instant override to Mode D from any state. One click disables all AI execution across your entire organization. The kill switch is always accessible regardless of current mode, role, or policy state.
POLICY GOVERNANCE
Canary deployment. Version history. Automatic rollback.
Policy Versioning
Every policy change creates a new version. Versions are immutable — you can see the exact policy state at any point in time. Policies progress through statuses: draft, approved, canary, active, rolled back. Each transition is recorded in the audit trail.
Canary Deployment
New policies deploy to a small subset of your operation first (e.g., 10% of customers). VAERION monitors metrics — lift, error rate, sentiment — during the canary period. If any governance threshold is breached, the policy automatically reverts to the previous verified version.
Additive-Only Schema
VAERION's database follows an additive-only migration policy. No tables are dropped. No columns are removed. No renames. Every schema change is strictly append-only, ensuring your historical data and audit records are structurally preserved across every platform update.
Bounded Execution
Every autonomous workflow operates within defined boundaries: maximum spend per day, maximum actions per customer per period, required consent checks at every dispatch point. Execution that exceeds any boundary is blocked and escalated. There is no unbounded AI execution in VAERION.
HEALTHCARE SECURITY
PHI-isolated infrastructure. BAA active. Fail-closed by design.
For healthcare organizations, VAERION operates a physically and logically separate infrastructure for all Protected Health Information. PHI processing, storage, and AI inference occur exclusively within a dedicated, BAA-covered environment.
BAA Active
Signed Business Associate Agreement covering all PHI processing, storage, and AI inference.
PHI Encrypted at Rest
All PHI is encrypted at rest using VAERION's key management system. Encryption keys are per-tenant and never exposed to application code.
Cryptographic Request Signing
Every request to the PHI infrastructure is cryptographically signed. No API keys to rotate or leak — authentication is identity-based.
Fail-Closed Communications
PHI-enabled tenants are blocked from all non-BAA communication providers at the infrastructure level. PHI cannot leak regardless of user action.
PHI Audit Trail
Every PHI access, AI call, and record retrieval is captured in an immutable audit log with actor identity, timestamp, and resource identifier.
Feature Flag Gating
The entire PHI pathway is gated behind an explicit feature flag. Healthcare routing is disabled by default and requires explicit enablement.
VAERION implements HIPAA-ready controls and operates under a signed Business Associate Agreement. "HIPAA-ready architecture" reflects the technical design of the system. Certification status and compliance obligations for your specific use case should be evaluated with qualified legal and compliance counsel.
INFRASTRUCTURE
Enterprise-grade. Globally distributed. Purpose-built.
Edge Computing Platform
VAERION's standard operations run on a globally distributed edge computing platform, delivering sub-50ms response times from anywhere in the world. The infrastructure is SOC 2 Type II certified for security, availability, and confidentiality.
PHI-Isolated Environment
Protected Health Information is processed in a physically separate, dedicated infrastructure environment with full HIPAA controls. PHI never traverses the standard processing path — it is routed through a dedicated gateway with its own storage, AI inference, and audit logging.
Multi-Model AI Architecture
VAERION operates four AI tiers (Core, Pro, Advanced, Apex) across multiple reasoning engines. Each tier is purpose-built for specific task categories. Healthcare AI calls are automatically routed through HIPAA-eligible inference infrastructure regardless of which tier is configured as default.
Automated Security Testing
Every code change runs through 18 automated pre-commit checks including permission seed verification, SQL column validation against schema DDL, canonical module enforcement, destructive SQL guards, consent tenant isolation checks, and identity header spoofing prevention. 10,500+ unit tests validate every module.
