77 Frameworks. 10 Languages. 1 Protocol.

The evidence clearing house
for AI compliance.

Every AI inference, every infrastructure control, every regulatory checkpoint -- witnessed, anchored, and independently verifiable. Your auditor visits, validates the math, and moves on. No opinions. No vendor lock-in. Just cryptographic proof.

Witness. Anchor. Verify. Move on.

278 Procedures. 80 Frameworks. 10 SDKs.

Every AI action witnessed and mapped to the framework your auditor cares about. 279 procedures across 80 regulatory frameworks. SDKs in 10 languages. 60,000+ downloads.

Three Promises

Anchors never drop. The auditor portal always loads. Verification always resolves. That is the entire service contract. Your evidence is recorded, your auditor can access it, and anyone can verify it.

Completeness Scoring

'37 of 43 required procedures have evidence.' Your auditor sees exactly what is witnessed and what is missing. Gap visibility creates trust. The clearing house shows the full picture, not a cherry-picked subset.

Auditor Findings

Your auditor annotates anchors with findings directly in the portal. You see the findings in your dashboard and resolve them. The collaboration loop that makes neither side want to leave.

The Witness Engine

Deterministic Evidence, Not Opinions

The SDK witnesses every AI action and evaluates it against published rules with a deterministic equation: same inputs, same verdict, every time. Every verdict passes through three cryptographic stages before it becomes an immutable Witness Anchor. Evidence in. Proof out. Nothing else.

1

Provenance

Machine-Gathered Evidence

The SWT3 SDK observes AI inferences, tool calls, and agent actions at the point of execution. Evidence factors are captured and hashed locally. No self-reporting. No screenshots. Every observation is tagged with its origin before it leaves your system.

2

Adjudication

Deterministic Verdict

The Universal Adjudicator evaluates evidence against verdict rules published in your control library. factor_a vs. factor_b. Greater than, less than, equal to. The same inputs produce the same verdict every time. Math, not opinions.

3

Witness Anchor

Cryptographic Proof

The verdict is SHA-256 fingerprinted, minted into an SWT3 Witness Anchor, and written to the append-only ledger. Raw telemetry is surgically purged. You retain the proof. We never retain your data.

// Witness Anchor: adjudicated, sealed, recorded

Independently Verifiable

Assessor Workbench

Your auditor gets a dedicated clearing house portal. Read-only access, full ledger visibility, zero write permissions. They re-derive every anchor on their own terms. When the math is indisputable, the audit is a formality.

Legacy GRC Platforms

Manual + API-Polling Model

  • No visibility into what AI models actually did
  • Evidence is self-reported by the operator
  • No cryptographic proof of assessment
  • AI governance tracked in spreadsheets and tickets
  • Auditor must trust screenshots, not math
  • Assessment artifacts assembled manually over weeks

Axiom Clearing House

Evidence Recording + Auditor Verification

  • SDK witnesses AI actions at the point of execution
  • Evidence is machine-gathered, never self-reported
  • Every verdict is SHA-256 fingerprinted into an SWT3 anchor
  • 279 procedures across 80 regulatory frameworks
  • Auditor portal with findings, completeness scoring, and decision chains
  • Assessment acceleration: auto-triage 200 controls, flag 15 for review
  • Bring your own infrastructure scans via evidence ingestion

Their compliance is self-attested. Ours is witnessed.

Bring Your Own Evidence

Already have compliance artifacts from other tools? Keep them. Ingest scan results, assessment reports, or any evidence file into the clearing house and we anchor them alongside your AI witness data. Your auditor sees one unified evidence chain -- verified the same way, in the same portal.

Check Compliance from Your Terminal

Developers live in terminals, not dashboards. swt3 status shows your completeness score, anchor count, expiring evidence, and open auditor findings without opening a browser. Like terraform plan for compliance.

Assessment Acceleration

Schedule an assessment window. The triage engine evaluates every procedure in the framework, auto-verifies controls with cryptographic fingerprints, and flags only failures and gaps for the human assessor. Your assessor reviews 15 flagged items instead of manually checking 200 controls. One-click report generation from verified evidence. The assessment itself becomes evidence in the ledger.

Assessment-Ready by Design

Axiom generates three OSCAL artifacts (the SSP, POA&M, and Assessment Results) as a single bundle, cross-validated and verified against the NIST reference implementation before they leave the system. POA&M entries cite verbatim DISA fix text from the official XCCDF benchmarks. Every artifact is backed by a cryptographic Witness Ledger the assessor can independently verify. Less time in interviews. More time in evidence review. Shorter audits for everyone.

Are you a C3PAO, 3PAO, or Notified Body? Contact us about our dedicated Assessor Verification tools and read-only auditor portal.

Axiom is an independent third-party evidence platform. It does not grant certifications, issue conformity assessments, or replace the professional judgment of a qualified assessor.

Axiom is an independent third-party evidence platform. The auditor is the judge. Axiom continuously collects, adjudicates, and witnesses compliance evidence using deterministic rules and cryptographic proof. It does not grant certifications, authorize systems, issue conformity assessments, or replace the professional judgment of a qualified assessor, Notified Body, or Authorizing Official. Scores, gate decisions, and recommended outcomes are computed deterministically from machine-gathered evidence and are provided for informational purposes only. The SWT3 Witness Ledger provides a tamper-evident record of what was assessed, when, and with what result. The final authority on compliance or conformity rests with the designated assessment body and their professional standards.
