What is an SBOM?

Section titled “What is an SBOM?”

A Software Bill of Materials (SBOM) is a structured, machine‑readable inventory of the components, libraries, and dependencies inside a software product.
Think of it like a food label: it tells you what went into the software, which versions are used, and where each component comes from.

At minimum, an SBOM typically includes:

  • Product name and version
  • List of components and their versions
  • Supplier or source of each component
  • Unique identifiers (e.g., PURL, CPE) and dependency relationships
  • Timestamp and author of the SBOM data

Common formats such as CycloneDX and SPDX make SBOMs easy to process automatically in tooling and pipelines.

Why SBOMs matter

Section titled “Why SBOMs matter”

Modern applications are assembled from many third‑party components, creating complex software supply chains.
When a new vulnerability is disclosed, teams often struggle to answer a simple question: “Are we affected, and where?”.

SBOMs create the transparency needed to:

  • Find vulnerable components quickly and prioritize remediation.
  • Support compliance with customer, sector, and regulatory expectations.
  • Manage technical debt by detecting outdated or unsupported components.
  • Increase supplier transparency by sharing software composition details with customers and partners.

This website helps you understand SBOMs and start using them in your own projects or organization.

How to get started with SBOMs

Section titled “How to get started with SBOMs”

The term “SBOM” refers to a concept implemented primarily through the CycloneDX and SPDX standards.
SBOMs can be generated at different stages of the software development lifecycle, and the most useful form depends on your role and use case.

If you’re just starting out, a simple approach is:

  1. Assess your environment
    and identify business‑critical applications.
  2. Pick a tool that matches your stack (e.g., containers, packages, language ecosystems).
  3. Generate or request your first SBOM
    by building it yourself or requiring it from your vendors.
  4. Validate and store
    the SBOM securely and make it available to the right stakeholders.
  5. Keep it updated
    with each release and use it in vulnerability and license reviews.
