1. Company Overview

Legal EntityTenable Nova LLC
JurisdictionUnited States
Primary ProductSWT3 (Sovereign Witness Token v3): cryptographic accountability protocol for AI systems and regulated infrastructure
PlatformAxiom Sovereign Engine: compliance evidence platform built on the SWT3 protocol
Websitetenova.io (corporate), sovereign.tenova.io (platform)
Business ModelProtocol-first. SWT3 is an open specification; SDKs are open source (MIT). Axiom is the commercial platform for evidence management, reporting, and audit exports.

TeNova builds the SWT3 protocol, which generates cryptographic witness anchors for AI inferences, governance decisions, tool access events, and agent handoffs. These anchors are independently verifiable using standard SHA-256. No proprietary tooling is required for verification.

The protocol is designed for regulatory compliance across multiple frameworks simultaneously. A single integration produces evidence that maps to 77 regulatory frameworks, including NIST 800-53, CMMC, EU AI Act, NIST AI RMF, and SR 11-7.

3. Data Handling

3.1 What Is Stored

The SWT3 witness ledger stores metadata and cryptographic hashes only. The following table describes what crosses the network boundary and what remains within the customer's infrastructure.

Stored in Witness LedgerNever Leaves Customer Infrastructure
SHA-256 fingerprint (12 hex characters)Raw prompts and user inputs
Numeric compliance factors (integers)Raw model responses
Clearing level designation (0-3)Model weights and parameters
Millisecond-precision timestampTraining data
Procedure identifier (e.g., AI-INF.1)PII and sensitive content
Verdict (PASS/FAIL)System prompts
Tenant and model identifiersEmbedding vectors
Key point: No PII, model weights, prompts, responses, or inference content is stored in the witness ledger. Raw data never leaves the customer's infrastructure. Only cryptographic hashes and numeric metadata cross the wire.

3.2 Clearing Levels

The SWT3 protocol defines four clearing levels for data classification. Customers control which level applies to each witness anchor.

LevelNameDescription
0AnalyticsMaximum metadata retained for internal analysis
1StandardDefault. Raw evidence purged at source before transmission
2SensitiveReduced metadata. Model identity and prompt hashes included
3ClassifiedMinimum metadata. Model identity is hashed. Suitable for classified environments

4. Compliance Frameworks

4.1 Supported Frameworks

The SWT3 protocol and Axiom platform support 77 regulatory frameworks through a crosswalk registry. Each accountability procedure maps to one or more framework controls via the registry.

FrameworkCoverage
NIST 800-53 Rev 5123 active controls, 72 PASS, 9 INHERITED. Self-assessed.
CMMC Level 2Full crosswalk mapping via CCI bridge
FedRAMP ModerateCrosswalk support with OSCAL export
NIST AI RMF (AI 100-1)Full crosswalk via AI namespace procedures
EU AI Act (incl. GPAI Art. 51-56)Full crosswalk via AI namespace procedures
SR 11-7 (OCC Model Risk)Full crosswalk via AI namespace procedures
NIST 800-171 Rev 2CUI protection crosswalk
ISO/IEC 42001AI management system crosswalk

The full list of 77 frameworks is available in the public UCT Registry.

4.3 OSCAL Export

4.4 W3C Verifiable Credentials

5. Business Continuity

5.1 Continuity Planning

5.2 Key Person Risk Mitigation

Protocol independence: SWT3 is a published open specification. Any organization can implement the protocol from the published spec without depending on TeNova. SDKs are open source (MIT license) and published to 11 package registries. Key person risk does not affect protocol availability.

5.3 Evidence Integrity

6. Subprocessors

SubprocessorFunctionData ProcessedCertifications
Vultr Compute infrastructure (US data center) Application runtime, log storage SOC 2 Type II
Supabase Database and authentication Tenant metadata, witness anchors (hashes only), user credentials SOC 2 Type II, HIPAA BAA available
Stripe Billing and payment processing Payment method, billing address, subscription status PCI DSS Level 1
GitHub Source control, SDK distribution, container registry Source code, SDK packages, container images SOC 2 Type II
Data minimization: No customer inference data, PII, model weights, or prompt content is shared with any subprocessor. Subprocessors receive only operational metadata necessary for their function (hashes, timestamps, subscription status).
