Trust, proven by cryptography. Not promises.
Runs on your laptop. Signs every finding. Your auditor verifies the math — offline.
How a single answer becomes proof
Watch a finding become cryptographic proof.
The only AI governance auditor that runs on your laptop, keeps every document on your machine, and signs every finding with verifiable evidence. 12 frameworks. $299/month. No demo required.
You ask a question
plain English, on your machine
Probatum finds the evidence
cited and reranked — never invented
It checks every claim
ungrounded claims get flagged, not shipped
It signs and seals the proof

“Does our password policy meet SOC 2 CC6.1?”
Tamper-evident. Change one byte and the proof breaks.

The cost of compliance theater
Every quarter you delay, the math gets uglier.
The frameworks aren’t getting softer. The fines aren’t getting smaller. And the questionnaires aren’t getting shorter.
Average cost of a data breach — the bill arrives whether or not your evidence was real.
Maximum EU AI Act fine — or 7% of global turnover, whichever is higher. Enforcement begins phasing in 2026.

The paradigm shift
Your auditor wants evidence, not theater.
Compliance vendors built spreadsheet factories. Probatum builds the only thing an auditor can actually verify — math.
Compliance theater
- ✕Months of manual prep
- ✕Spreadsheets your auditor has to trust
- ✕Reports only verifiable inside the vendor portal
- ✕AI hallucinations silently enter evidence
- ✕Audit trail editable by the vendor
- ✕Your documents shipped to a SaaS cloud
Trust-Native
- ✓Answers in seconds — not months
- ✓Cryptographic proof auditors verify offline
- ✓Every claim grounded; hallucinations flagged
- ✓12 frameworks, unified
- ✓Hash-chained audit log — tamper-evident
- ✓Documents never leave your machine
What makes it different
Six things no demo-gated SaaS can match.
Tamper-proof history auditors trust
SHA-256 linked entries. Alter any record and the chain breaks — immediately detectable.
Signed evidence your auditor verifies offline
Ed25519-signed W3C VCs. Your auditor verifies independently — no account, no portal, no trusting you.
Your documents never leave your machine
LLM inference, embeddings, and vector search all run locally on your device. Zero data egress.
Every answer grounded — or flagged
Claims that can't be traced to evidence are flagged before they enter the record. No silent hallucinations.
12 frameworks, one platform
Dedicated control-mapping for SOC 2, ISO 27001, HIPAA, PCI-DSS, GDPR, NIST CSF, EU AI Act, and more.
Every claim cites its source
Cross-encoder reranked retrieval. Every answer cites the exact document and paragraph.

Does our password policy satisfy SOC 2 CC6.1?
- Sending query (local-only)
- Retrieving & reranking evidence
- Grading for grounding
- Signing & chaining
security_policy_v3.pdfp. 4“Passwords must be at least 12 characters and include a mix of uppercase, lowercase, numbers, and symbols.”
access_review_2024_q3.pdfp. 1“Quarterly access review completed 2024-09-15. All privileged accounts verified and recertified.”
Your password policy satisfies CC6.1. Evidence: 12-char minimum enforced, MFA required for admins, quarterly access reviews documented.

Cryptographic proof
Verify any audit report — yourself. No account.
Every evidence report ships as a W3C Verifiable Credential. Your auditor checks the Ed25519 signature and revocation status without logging into a portal. The proof is portable, public, and falsifiable.

- Revocation via W3C StatusList2021
