EU AI Act high-risk enforcement begins August 2, 2026. Can you prove your AI followed the rules?
Defining the AI Accountability Standard

One protocol. Zero Integrity Debt.

Cryptographic accountability
for AI and regulated infrastructure.

The first flight recorder for AI accountability.

Every AI inference, every infrastructure control, every regulatory checkpoint - witnessed, fingerprinted, and sealed into a tamper-evident record. Machine-gathered evidence. Deterministic verdicts. Proof that both sides of the table can independently verify.

What We Build

One protocol. Two products. Trusted integrity for defense, finance, healthcare, and AI governance.

Infrastructure Compliance

Axiom Sovereign Engine

Continuous compliance evidence for NIST 800-53, CMMC, FedRAMP, and 9 more frameworks. 210 controls scanned, adjudicated, and anchored with the SWT3 protocol. Agentless. Cloud, on-prem, or air-gapped. OSCAL-validated exports for C3PAO assessments.

AI Accountability

SWT3 AI Witness SDK

Cryptographic attestation for every AI inference. Prove your models are running approved weights, guardrails are active, and inferences are traceable. Zero data retention. Three lines of code. Works with OpenAI, Anthropic, Vercel AI SDK, Bedrock, Ollama, and any OpenAI-compatible endpoint.

Regulatory Coverage

Native mapping to the frameworks that matter. Not a crosswalk bolted on after the fact.

How It Works

Three phases. No agents installed. No data retained.

01

Witness

The SDK or scanner observes your AI inference or infrastructure control. Evidence factors are captured and SHA-256 hashed at the point of observation.

02

Anchor

Factors are sealed into an SWT3 Witness Anchor - a tamper-evident, cryptographic receipt binding evidence to a verdict at a specific moment in time.

03

Verify

Any party can independently verify the anchor using the open-source library or the browser-based verifier. No API keys. No vendor access. SHA-256 runs locally. Just math.

The Clearing Engine

The proof survives the data. The data doesn't outlive its purpose.
100% auditability with 0% data liability.

L0

Analytics

Hashes, factors, model ID, provider, and guardrail names. For internal analytics and non-sensitive workloads.

L1

Standard

Default. Hashes and factors only. No raw prompts or responses on the wire. Production-grade privacy.

L2

Sensitive

Hashes, factors, and model ID only. No provider metadata. Built for healthcare, legal, and PII-adjacent workloads.

L3

Classified

Numeric factors only. Model ID hashed. Zero metadata. Built for defense, air-gapped, and classified environments.

Proxies monitor traffic. We witness execution.

AI Governance Proxies

Sit between your app and the model. Can be bypassed. Cannot see inside private enclaves. Store prompts and responses on their servers. Single point of failure for compliance.

SWT3 Witness (SDK-Level)

Embedded in your execution logic. Cannot be bypassed. Works inside private enclaves, air-gapped networks, and sovereign clouds. Stores only cryptographic proofs. Verification is independent and offline-capable.
