SBOM Evidence Bundle

The signed artifact your auditor or customer accepts in lieu of a portal access.

The SBOM Evidence Bundle is a signed package WASViking® builds directly from your tenant data. It is the artifact you hand to an auditor, a customer due-diligence team, or a regulator, without giving them portal access.

What is in the bundle

Artifact Notes
CycloneDX 1.5, per submission Original Sentinel submissions, signed.
Consolidated CycloneDX Org-wide aggregate at bundle creation time.
Cover PDF Brand cover, executive summary, organization metadata.
Drift CSV Component drift over the chosen window.
Findings CSV Open and accepted findings tied to components.
Audit CSV Audit log slice scoped to the bundle window.
Compliance CSV Per-control hits for the primary catalog.
verification.txt The chain of signatures and how to verify them.

How it is shared

Token plus password, time-limited, revocable. Same model as Posture Shares.

  1. Operator clicks Inventory → SBOM → Generate Bundle.
  2. WASViking builds and signs the bundle.
  3. Operator gets a one-time share URL and a separate password.
  4. Operator delivers each piece out of band (the URL by email, the password by phone or chat, for example).
  5. Recipient enters the password on first access and downloads.

Bilateral audit log records every access on both sides. Operators can revoke any time; revocation is immediate.

How verification works

verification.txt documents:

  • The signing chain for every artifact in the package.
  • The signature algorithm and key fingerprint.
  • The bundle creation time and the window it covers.
  • The hashing strategy for the consolidated CycloneDX.

A recipient can verify with:

# Pseudocode; the file contains exact commands per artifact
cosign verify-blob \
  --signature bundle.sig --certificate bundle.crt \
  --certificate-identity-regexp '^[email protected]' \
  --certificate-oidc-issuer https://accounts.google.com \
  consolidated-cyclonedx.json

The WASViking signing identity and OIDC issuer for each environment are listed in the file.

API

Method Path Scope Purpose
POST /v1/sca/bundles evidence.share Issue a bundle.
GET /v1/sca/bundles sca:read List bundles for the org.
POST /v1/sca/bundles/{id}/revoke evidence.share Revoke a bundle.
GET /v1/sca/bundles/{id}/audit audit_logs:read Access log.

Example, issue a bundle:

curl -sS https://api.wasviking.com/v1/sca/bundles \
  -H "Authorization: ApiKey ${KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "window_days": 90,
    "include": ["sbom", "drift", "findings", "audit", "compliance"],
    "description": "Customer XYZ due diligence"
  }'

Response:

{
  "id": "bundle_88aa12",
  "share_url": "https://posture.wasviking.com/b/88aa12d4",
  "password": "9F7K-X3WT-4B2P-LMNE",
  "expires_at": "2026-08-19T00:00:00Z",
  "scope": ["sbom", "drift", "findings", "audit", "compliance"]
}

Both share_url and password are shown once at issuance. Store them.

When to use it

  • Customer due diligence. Replace the PDF dump with a verifiable artifact your prospect can validate.
  • Auditor binder. Attach the bundle to the per-control evidence in your audit binder.
  • Procurement gates. Some procurement processes ask for an SBOM and proof of continuous scanning. The bundle answers both.

When NOT to use it

  • For ad-hoc internal sharing inside your organization, the portal Compliance tab is faster.
  • For a Slack channel notification, use webhooks; the bundle is not the right unit.
