AttestLayer

Review-ready proof for operational evidence

Turn exported evidence into a proof package reviewers can actually use

Use AttestLayer when screenshots, ticket threads, and ad hoc exports are too weak to forward. Teams submit exported artifacts they already have. AttestLayer returns deterministic PASS or FAIL and, on PASS, a signed package reviewers can verify in the browser or offline.

Record-only company model

AttestLayer works from submitted artifacts rather than direct access to customer systems.

Signed proof outputs

PASS produces a receipt, manifest, and review-ready package with clear provenance.

Verification beyond delivery

Browser verification, offline checks, and registry publishing support stronger downstream review.

What AttestLayer is

A record-only evidence company for workflows that need stronger provenance

AttestLayer helps organizations turn exported artifacts into signed proof packages for change review, procurement review, audit follow-up, partner validation, and similar operational workflows. Teams submit artifacts they already have. AttestLayer evaluates the submission, binds PASS output into a signed verification kit, and makes verification available in the browser or offline.

The company takes a narrow role on purpose: improve packaging, provenance, and verification without requiring software inside customer infrastructure or a large process overhaul.

Example inputs

  • Exported security-review evidence
  • Change approval or release evidence
  • Procurement proof packets
  • Vendor or partner review evidence
  • Incident follow-up artifacts
  • AI governance or operating-control evidence

Example outputs on PASS

  • Signed verification kit
  • SHA-256 manifest
  • Ed25519-signed receipt
  • Registry-linked proof material
  • Offline verifier
  • Reviewer-forwardable proof package

Common uses

  • Change approvals and release evidence
  • Buyer and procurement review
  • Audit follow-up and dispute defense
  • Partner and vendor validation

What it is not

  • Not an audit opinion or certification
  • Not a compliance consultancy
  • Not an agent inside customer systems
  • Not a requirement to replace existing tools

VerificationLocal or offline verification path

Best fit organizations

  • B2B software companies moving into more serious buyer review
  • AI vendors needing stronger proof packaging
  • Technical vendors with real artifacts but weak external packaging
  • Teams dealing with procurement, security review, or counterparty validation

What the output looks like

A PASS gives reviewers a clear, signed package

The output is shaped for handoff: understandable by reviewers, grounded in provenance, and verifiable without direct access to AttestLayer operations.

Integrity

Each file is indexed in a SHA-256 manifest so reviewers can see exactly what was bound into the package.

Provenance

The receipt is Ed25519-signed and linked to the manifest so the output can be independently checked later.

Verification path

Use verify.attestlayer.com or the bundled offline verifier without needing an account or private infrastructure access.

The proof model at a glance

1 Submit

Upload artifacts you already have

2 Evaluate

Deterministic PASS or FAIL

3 Bind

PASS is sealed into a signed kit

4 Verify

Review locally in-browser or offline

5 Forward

Send a review-ready package internally or externally

Bounded outcomes with review-ready output

PASS

A signed verification kit is issued with a manifest, receipt, offline verifier, and a package that can be shared onward.

FAIL

A bounded blocker list is returned so teams can see what prevented issuance and what needs correction before resubmission.

On issuance, each proof package includes:

Signed manifest Ed25519 receipt Offline verifier Forwardable package

See the operating flow

See how exported artifacts move through evaluation, issuance, and verification in a browser-based workflow.

How it works

  1. Submit evidence you already have

    Export artifacts from your existing workflow — tickets, logs, approvals, change records, or related materials — and upload them through the browser.

  2. AttestLayer evaluates and binds

    AttestLayer returns deterministic PASS or FAIL. On PASS, the artifacts are bound into a signed, verifiable record with clear provenance and integrity checks.

  3. Forward or verify the result

    Use the resulting proof kit for internal approval, audit follow-up, dispute defense, partner review, or downstream verification.

Why organizations use AttestLayer

Replace manual evidence assembly

Stop stitching screenshots, exports, and ticket fragments by hand. AttestLayer packages raw artifacts into a structured, signed proof output.

Give reviewers something usable

Instead of forwarding messy internal evidence, teams can send a clean, review-ready package for approvals, client review, or audit follow-up.

Reduce operational exposure

No installs. No system access. No agent footprint. The model stays record-only, so teams keep control of production systems.

Keep proof independently verifiable

Receipts and manifests can be verified later, making the output stronger than informal documentation when defensibility matters.

Stronger than screenshots, ticket threads, and ad hoc approvals

Most teams already have evidence, but not in a form that is structured, review-ready, easy to forward, or easy to defend later.

Typical current process

  • Screenshots and exports assembled manually
  • Approval context scattered across tools
  • Hard to forward cleanly
  • Weak consistency across teams
  • Difficult to verify later

With AttestLayer

  • Structured, signed proof output
  • Clear record of what was submitted
  • Review-ready forwardable package
  • Repeatable handling across workflows
  • Offline-verifiable when defensibility matters

Verification and trust foundations

  • Cryptographically signed receipts (Ed25519)
  • SHA-256 manifest for every submission
  • Offline verification support
  • Record-only operating model — no system access
  • Published security model and verification documentation
  • GCP northamerica-northeast1 (Montréal) data residency

Access paths in more detail

The chooser above is the short version. These paths add more context on who each AttestLayer surface is built for and what each one is expected to handle.

Direct buyer path

Start here if your team is buying for itself and needs the main AttestLayer commercial and evaluation flow.

  • Pilot, activation, and monthly coverage
  • Sample kit, trust, and docs in one surface
  • Straight path for direct organizational use
Open buy.attestlayer.com

Partner path

Start here if you run MSP, distributor, reseller, or multi-client programs that need reserved capacity and structured commercial terms.

  • Reserved capacity tiers
  • Multi-client operating model
  • Structured rollout and commercial path
Open partners.attestlayer.com

Review and verification path

Start here if a kit already exists and you only need to inspect, validate, or forward proof output rather than purchase a plan.

  • Browser-based proof inspection
  • Offline verification path
  • Clean route for downstream review
Open verify.attestlayer.com

Registry and trust path

Start here if you are doing technical trust review and need keys, checkpoints, or transparency material without entering a commercial flow.

  • Issuer keys and verification support
  • Checkpoints and transparency material
  • Independent trust review over time
Open registry.attestlayer.com
