Verify it yourself
Don't take our word for it. Download a real (synthetic) Senthex proof bundle, run the offline verifier on your own machine, and change a byte to watch the check fail. The verdict in your browser equals the verdict from our offline Python tool.
Verify it yourself
Most AI-security tools ask you to trust them. Senthex gives you a verifiable record. Below is a real (synthetic) audit bundle — change one byte and watch the cryptographic chain catch it, live in your browser.
Flip the blocked attack's score 0.86 → 0.06 — an insider trying to hide it.
Editable. Nothing proves it wasn't changed.
{ "event": 13, "verdict": "block",
"injection_score": 0.86 }No integrity check — the edit is invisible. “Trust us.”
A SHA-256 hash chain — signed, Merkle-committed, and externally timestamped.
freeTSA is a public demo authority (not eIDAS-qualified); in production the timestamp is a qualified eIDAS QTSP — same mechanism. All three are checked by the offline verifier.

100% synthetic data (ACME Talent GmbH). This proves integrity (an unbroken chain, not silently rewritten), origin (each checkpoint is signed with a composite Ed25519 + ML-DSA-65 key), and time (an external RFC 3161 anchor). The Merkle root commits to the set of events shown; proving none were omitted in a separate snapshot needs a cross-witness, which is deferred. Tamper-evident, not tamper-proof. The verifiable audit trail is a pilot capability (v1.1.7), not yet the published release.
Download the bundle + offline verifier
A self-contained zip: the proof bundle, a one-byte-tampered copy, and a pure-Python verifier — no database, no Senthex server, no trust required. 100% synthetic data; real SHA-256 chain + a real freeTSA RFC 3161 timestamp.
Download the bundle (zip)Python 3.11+ and three public libraries. Intact → chain_ok true, exit 0. Tampered → chain_ok false, exit 1.
pip install rfc3161-client cryptography httpx cd verifier python -m audit verify-export ../proof-bundle.json # -> "chain_ok": true, exit 0 python -m audit verify-export ../proof-bundle.TAMPERED.json # -> "chain_ok": false, exit 1

This proves integrity — an unbroken chain, not silently rewritten before the timestamped anchor. It does not prove completeness or origin. Tamper-evident, not tamper-proof. freeTSA is a public demo authority (not eIDAS-qualified); in production the anchor is a qualified eIDAS timestamp (QTSP) — same mechanism. Audit-as-proof is a pilot capability (v1.1.7), not yet the published release.
