The reference for CERT-In software supply chain security and the xBOM ecosystem
certinsbom.com is a continuously updated knowledge base covering SBOM, CBOM, HBOM, AIBOM, QBOM and CERT-In's software supply chain security guidelines — written for developers, security engineers, DevSecOps teams and CISOs, not for procurement.
certinsbom.com is an independent educational resource. It is not affiliated with, endorsed by, or a website of CERT-In or the Government of India.

You're not alone — start with the basics, at your own pace.
Our mission
Make software supply chain security understandable and actionable for every organization operating under CERT-In's guidelines — from independent developers to regulated banks.
- Vendor-neutral by design. We publish open-source and commercial tools side by side, and explain where each one fits rather than which one is "best."
- Mapped to primary sources. Every compliance page cross-references CERT-In's own guidance and the global standards it draws from — NIST SSDF, SLSA, NTIA, CISA.
- Written for practitioners. Developers, security engineers and compliance teams — not procurement decks.
- Reviewed, not static. Standards and guidance evolve; our editorial policy governs how and when pages get revisited.
What is software supply chain security?
Software supply chain security is the practice of securing every stage of how software is built, packaged, distributed and consumed — including the open-source libraries, build tools, CI/CD pipelines and third-party components that make up a modern application. A single weak link, a compromised build server, a poisoned dependency, an unsigned release artifact, can affect every downstream organization that depends on it.

Introduction to the xBOM family
A Bill of Materials is a structured, machine-readable inventory. What started with software has expanded into a family of related inventories, collectively called xBOM.
Software Bill of Materials
An inventory of every open-source and third-party component in a piece of software.
Cryptography Bill of Materials
An inventory of the cryptographic algorithms, keys and certificates used within a system.
Hardware Bill of Materials
An inventory of the physical components and firmware inside a device.
AI Bill of Materials
An inventory of the datasets, models and dependencies that make up an AI/ML system.
Quantum Bill of Materials
An emerging inventory format for quantum and post-quantum cryptographic components.

Enterprise solutions
Many organizations start with open-source tooling and later evaluate commercial platforms as their compliance program matures.
Need an enterprise solution? Compare commercial SBOM platforms including Certhy — alongside Dependency-Track, Black Duck, Mend, Snyk, Sonatype and Anchore — to see which fits your scale, sector and existing toolchain.
We never name a single product as "the best." Comparisons on this site always include open-source alternatives, and are scoped to where each platform genuinely fits — team size, sector, in-house tooling maturity. Read our editorial policy.

Frequently asked questions
Is certinsbom.com affiliated with CERT-In or the Government of India?
No. certinsbom.com is an independent, vendor-neutral educational resource. It is not a government website and does not speak on CERT-In's behalf. Always confirm regulatory requirements against CERT-In's own official publications.
What is a Software Bill of Materials (SBOM)?
An SBOM is a structured, machine-readable inventory of every component — open-source and proprietary — that makes up a piece of software, along with metadata like version and supplier. See our complete SBOM guide.
Is generating an SBOM mandatory under CERT-In's guidelines?
CERT-In's guidance addresses software supply chain security, including SBOM practices, but specific obligations vary by sector, organization type and the systems involved. See the Compliance Center for a detailed breakdown and always verify against CERT-In's official publications.
What's the difference between SBOM and the other xBOM types?
SBOM covers software components; CBOM covers cryptographic assets; HBOM covers physical hardware; AIBOM covers AI/ML datasets and models; QBOM covers quantum and post-quantum cryptographic components. See the xBOM family overview.
Do I need commercial software to generate an SBOM?
No. Mature open-source tools — Syft, Trivy, cdxgen, CycloneDX CLI — can generate SBOMs at no cost. Commercial platforms like Certhy, Dependency-Track and others add lifecycle management and VEX correlation that larger programs may eventually need. See our tool comparison.
How is the accuracy of this content maintained?
Pages are written against primary sources — CERT-In publications and the relevant standards bodies — and reviewed on a schedule described in our editorial policy. Found an error? Let us know.
