Audit-grade AI safety for every prompt.Bring your own AI.
Every prompt your team sends to AI passes through ZeroH Disclosure first. Field-level classification, policy-based redaction, cryptographic proof of what the AI saw. And what it never saw. Designed to sit beside Microsoft Copilot, internal agents, and any AI tooling your staff already uses. Patent-pending architecture (UK GB2604344.8).
How it works
Watch a prompt get cryptographically redacted before it reaches an AI
ZeroH Disclosure intercepts every prompt at the policy boundary. Sensitive fields are masked by your governance rules, the AI sees only the redacted version, and a signed, tamper-evident audit record is produced. Designed to be verifiable by your DPO and your regulator.

AI Safety Primitives, Cryptographically Verified
Every prompt classified at field level. Every redaction signed and tamper-evidently recorded. Every disclosure designed to be third-party verifiable. Aligned to PRA SS1/23, EU AI Act, QCB, CBUAE, and GDPR.
Prompt-Layer Interception
Every prompt your team sends to AI is intercepted at the policy layer before it reaches the model. Field-level classification identifies PII, PHI, financial sensitivity, and Shariah-sensitive content. Redaction is applied under your disclosure policy.
Tamper-Evident Proof of Non-Disclosure
Most audit logs prove what happened. ZeroH Disclosure is designed to prove what did not happen. That a specific PII field was redacted before the prompt reached the model, under a specific policy, at a specific time. Tamper-evidently recorded; designed to be verifiable by any third party.
Selective Disclosure
Share proof of compliance without exposing the underlying data. Your auditor sees what they need; your regulator sees what they need; nobody sees more than they need. Designed to use cryptographic proof, not editorial redaction.
Deterministic, Rule-Based Classification
Classification rules are deterministic. Not probabilistic AI guesses. Every redaction decision is traceable to a specific regulation article (GDPR Article 5, AAOIFI FAS 4, Qatar PDPPL, QFC DPR). Auditable. Reproducible. Defensible.
On-Premise Data Residency
Original documents and source data stay on infrastructure under your control. Only redacted content leaves your perimeter. Tamper-evident audit anchors are designed to be written with on-soil storage where available. Schrems II and Gulf data residency compliant by architecture.
Proof Packs on Demand
Generate regulator-grade evidence in one click: what your AI saw, what it never saw, under what policy, with what timestamp. Designed to support evidence under PRA SS1/23, EU AI Act Article 12, QCB AI guidance, CBUAE responsible AI principles, and GDPR Article 35 DPIA evidence.
Why ZeroH Disclosure Instead of LLM Security Tools or DLP
Cryptographic Proof, Not Vendor Assertion
LLM security platforms deliver runtime LLM security. Prompt injection defence and model integrity. Microsoft Purview and Google DLP do file-level redaction. None produce cryptographic, third-party-verifiable proof of what an AI saw and never saw. ZeroH Disclosure is designed to.
Bring-Your-Own-AI, Not Vendor Lock-In
ZeroH Disclosure sits beside the AI your team already uses. Microsoft Copilot, ChatGPT Enterprise, Claude, internal LLM deployments, custom agents. No need to switch vendors. Specific plugin integrations (Microsoft 365 Copilot, browser extension, MCP servers) are in active development.
Regulator-Grade Evidence, Pre-Mapped
Proof packs are designed to support evidence requirements under PRA SS1/23 model risk, EU AI Act high-risk system logging, QCB AI guidance, CBUAE responsible AI principles, NIST AI RMF, ISO 42001, and GDPR Article 35 DPIA evidence. One product satisfies multiple supervisors at once.
