Zero Trust, Zero Knowledge
Prove what your AI says. Reveal nothing.
Cryptographic proof your AI stays within policy — verified by auditors, banks and customers without access to your data.
AI governance · Early access
Governing what AI does isn’t the same as governing what it says.
Most tools stop an agent from taking the wrong action. ZTZK also governs the claims your AI makes — and proves it, call by call.
Policy, enforced
Rules for personal data, disclosure, bias and agent boundaries run as each request happens — no extra model calls.
Unsupported claims, blocked
When your AI can’t back up an answer, it declines instead of guessing.
Every decision, signed
What your AI said — and what it refused to say — is kept as a signed record your auditor or examiner can check.

The problem
Compliance evidence can’t prove itself.
Today’s evidence is gathered at a point in time, vouched for by the company it describes, and proven only by handing over the data it’s meant to protect. None of it can be checked independently — so every auditor, bank and customer has to take it on trust.
How it works
From control to verifiable proof.
Every control follows the same path: turned into a rule, checked against live evidence where your data lives, signed, and recorded so anyone can verify it — without calling us.
Map
Each control becomes a precise, versioned rule — so every result records exactly which rule it was checked against.
Versioned rulesCollect
Checks run continuously against your code and connected systems, inside your own infrastructure. Your data stays where it is.
Continuous · in your systemsProve
Each result is signed with post-quantum cryptography and kept in a tamper-evident ledger. Sensitive facts are proven with zero-knowledge proofs instead of disclosed.

Why it holds up
Proof you can hand to anyone.
Give an auditor, a bank or a customer proof they can check themselves — without handing over your data or asking them to take your word for it.
Still valid years from now
Signed with post-quantum cryptography (ML-DSA-65), so your proof holds up even after today’s encryption is broken.
Nothing sensitive changes hands
They confirm the fact. They never see the record behind it.
Zero KnowledgeNo one has to trust you — or us
Anyone can check a proof on their own. The math is the authority.
Zero TrustOne engine, two markets
Prove your AI. Prove your compliance.
The same signed ledger answers two questions every regulated company now gets asked: is your AI doing what you said it would, and are your controls working?

Why ZTZK
Compliance tools collect. ZTZK proves.
Most compliance platforms gather evidence from your cloud accounts and present it for someone to review. ZTZK checks your code and systems directly and signs proof anyone can verify.
- Reads cloud account settings — little view into your code
- Evidence reviewers take on trust
- Evidence that can be changed after the fact
- Hand over the data to prove anything
- A scramble before every audit
- Scans your code in CI — evidence at the source
- Signed proof anyone can verify
- Post-quantum signed, append-only ledger
- Zero-knowledge — prove without revealing
- Continuous — always audit-ready
FAQ
Questions, answered
What is AI governance with ZTZK?
ZTZK enforces your AI policy on every call — blocking claims your AI can’t back up, personal data leaks and out-of-bounds agent actions — and signs a record of each decision, including what the AI declined to answer. Auditors, banks and customers can verify that record without access to your data.
What is ZTZK?
ZTZK — Zero Trust, Zero Knowledge — is a compliance and AI governance platform that turns controls into cryptographic proof. Evidence is collected from your code and connected tools, signed to an append-only ledger, and verified independently by auditors, bank partners and customers without exposing the data behind it.
How is ZTZK different from other compliance platforms?
Most platforms collect evidence and present it for someone to review. ZTZK signs every result so it can be verified independently, proves facts without revealing the underlying data, and works alongside the platform you already use.
Which frameworks does ZTZK support?
AI governance — runtime enforcement, model risk under SR 26-2 / OCC 2026-13 and ISO/IEC 42001 — plus SOC 2, HIPAA, ISO 27001 and BSA/AML. All are in early access.
Does our data leave our environment?
No. Checks run where your data lives, and only proofs leave your systems. Whoever verifies a proof never sees the records behind it.
What does post-quantum mean here?
Results are signed with ML-DSA-65, the NIST-standardized post-quantum signature scheme, so the record stays verifiable even once today’s widely used signatures can be broken.
How do we get started?
Request access. ZTZK is onboarding a small number of early teams and will walk you through the evidence for the framework you need first.
Trust shouldn't have to be rebuilt every time the world changes underneath it. Now it doesn't.
