SecureSBOM

SBOM signing and verification

Trust the SBOM before you trust the software.

SecureSBOM gives software producers and consumers a practical way to prove SBOM authenticity, detect tampering, and support audit-ready software supply chain workflows.

Integrity

Detect tampering

Verify that an SBOM has not been modified after signing.

Authenticity

Prove authorship

Connect SBOM data to the organization or workflow that created it.

Operations

Automate trust

Use APIs and CI/CD integrations instead of fragile manual verification steps.

Why SecureSBOM?

SBOMs are only useful when teams can trust them. A complete component list still leaves risk if the document can be spoofed, silently modified, or disconnected from the build process that produced it.

SecureSBOM focuses on the trust layer around SBOMs:

  • Standards-aligned signing for CycloneDX and detached signature workflows for SPDX
  • Managed key infrastructure so teams do not have to operate their own PKI
  • Online and offline verification for CI/CD, vendor review, clean-room, and air-gapped workflows
  • Audit evidence for security reviews, customer requests, and compliance programs

2026 SBOM minimum elements

Author signatures are now part of the baseline conversation.

The July 29, 2026 CISA, NSA, FBI, and international partner update to the SBOM minimum elements adds SBOM Author Signature as a new element, along with SBOM version, tool metadata, component hashes, and component license data.

That matters because SBOM programs are moving beyond inventory. Buyers and operators increasingly need evidence that the SBOM came from the claimed author and was not changed after generation.

How It Works

For SBOM producers

  1. Generate SBOMs from builds, source code, containers, or release artifacts.
  2. Sign them through the SecureSBOM API, CLI, or CI/CD integration.
  3. Distribute signed SBOMs with releases, customer evidence packages, or internal records.
  4. Archive signing metadata for repeatable audits and incident response.

For SBOM consumers

  1. Receive SBOMs from vendors, internal teams, or release pipelines.
  2. Verify author signatures and document integrity before analysis.
  3. Enforce policy in CI/CD, procurement, vulnerability management, or GRC workflows.
  4. Reuse previously verified SBOMs when assembling larger product inventories.

Built For Real Supply Chain Workflows

API-first integration

Integrate signing and verification into existing release, vendor, and compliance workflows.

CI/CD support

Use native pipeline integrations, including GitHub Actions, to sign SBOMs during release automation.

Managed key protection

Avoid spreading private signing keys across build systems and developer machines.

Offline verification

Support clean-room, regulated, and air-gapped environments that cannot call an external service.

CycloneDX and SPDX

Support common SBOM formats used by producers, consumers, and tooling ecosystems.

Audit evidence

Retain verification-friendly records that help answer customer, regulator, and incident-response questions.

Common Questions

What is SBOM Author Signature?

SBOM Author Signature is metadata that helps verify who authored an SBOM and whether the document has changed since it was signed.

Why sign an SBOM?

Signing turns an SBOM from an inventory claim into evidence that can be verified before it is used for vulnerability management, procurement, compliance, or incident response.

How does SecureSBOM support the 2026 SBOM minimum elements?

SecureSBOM focuses on the signature and verification layer around SBOM programs, including author signature workflows, managed key protection, and repeatable online or offline verification.
