Modern software is assembled, not written — a typical application is 70–90% third-party and open-source components. When one of those components is compromised, as with SolarWinds and Log4j, the blast radius is enormous. An SBOM makes the supply chain transparent; CertiNext makes it trustworthy.
What is a Software Bill of Materials?
A Software Bill of Materials (SBOM) is a formal, machine-readable inventory of every component, library, and dependency that makes up a piece of software — including names, versions, suppliers, licences, cryptographic hashes, and the relationships between them. It is the definitive record of what is actually inside the software you build or buy.
SBOMs are expressed in open, interchangeable formats — principally SPDX (ISO/IEC 5962) and CycloneDX (ECMA-424). A well-formed SBOM lets any consumer answer, in seconds, a question that used to take weeks: "Am I affected by this newly disclosed vulnerability?"
Why an SBOM Is Now a Requirement, Not a Nice-to-Have
Regulation has made SBOMs mandatory
US Executive Order 14028 established SBOMs for software sold to the federal government, and CISA's 2026 Minimum Elements for an SBOM raised the bar further. The EU Cyber Resilience Act now requires manufacturers of products with digital elements to maintain SBOMs and technical documentation, and sector regulators — including the FDA for medical devices — have followed. Producing SBOMs is fast becoming a condition of doing business.
Software supply chain attacks are the new front line
Attackers increasingly target the components everyone trusts rather than the perimeter. Without an SBOM, a single vulnerable dependency can hide undetected across your entire portfolio. With one, exposure is a query, not a fire drill.
The 2026 shift: SBOMs must now be signed
CISA's 2026 Minimum Elements introduce an SBOM Author Signature as an expected element — an SBOM is only trustworthy if you can prove who produced it and that it has not been altered. This is exactly where eMudhra, as a trusted Certificate Authority, is uniquely positioned: CertiNext can both generate your SBOM and cryptographically sign it.
CISA 2026 Minimum Elements — What a Compliant SBOM Must Contain
Document metadata
Author, author signature, data format & version, generation context, timestamp, tool name & version, SBOM version.
Per-component data
Producer, component name & version, unique identifiers (PURL/CPE), cryptographic hash & algorithm, licence, dependency relationships.
Practices
Transitive-dependency coverage, explicit handling of unknowns, machine-readable format, defined update frequency.
Compliant formats
CycloneDX 1.6 and SPDX 2.3 / 3.0.
How CertiNext Delivers Your SBOM
CertiNext extends its PKI and certificate lifecycle platform to generate, sign, and govern SBOMs — closing the trust gap most SBOM tools leave open.
Standards-Based SBOM Generation
Produce complete SBOMs in SPDX and CycloneDX formats, capturing transitive dependencies and all CISA 2026 minimum data fields — machine-readable and audit-ready.
Cryptographic Signing & Provenance
Sign every SBOM with trusted, publicly rooted certificates so consumers can verify authorship and integrity — satisfying the new SBOM author-signature expectation. Extend the same trust to code signing.
Vulnerability & Licence Mapping
Correlate components against known-vulnerability and licence data so security and legal teams can assess exposure and obligations from a single source.
Continuous SBOM Management
Version, store, and re-issue SBOMs across releases with full audit trails, keeping every artifact current and compliant as software and regulations evolve.
The eMudhra Difference
SBOMs You Can Actually Trust
Most tools can list what is in your software. Very few can prove it. As a globally trusted Certificate Authority, eMudhra brings the missing ingredient — verifiable trust. CertiNext lets you generate an SBOM and sign it with a trusted certificate, and pair it with code signing so the software and its bill of materials travel together as tamper-evident, verifiable artifacts. In a world where CISA now expects signed SBOMs, that is a decisive advantage.
An SBOM is the software half of the story — pair it with a Cryptographic Bill of Materials to see how it is protected, with Post-Quantum Cryptography Readiness to plan its migration to quantum-safe algorithms, and with Automated Certificate Lifecycle Management to keep the certificates that sign it under control.

Frequently Asked Questions
An SBOM is a formal, machine-readable inventory of all components, libraries, and dependencies in a piece of software, including versions, suppliers, licences, and cryptographic hashes. It lets you see exactly what is inside the software you build or buy.
An SBOM inventories software components and dependencies; a CBOM inventories cryptographic assets such as algorithms, keys, and certificates. Together they give complete visibility into both what your software contains and how it is protected.
They define the data every SBOM must include — document metadata (including an author signature), per-component details (producer, name, version, unique identifiers, hash, licence, dependencies), and practices such as transitive-dependency coverage and machine-readable format. CycloneDX 1.6 and SPDX 2.3/3.0 satisfy the requirements.
CertiNext generates SBOMs in both SPDX and CycloneDX, the two internationally recognised, interchangeable formats.
A signature proves who produced the SBOM and that it has not been tampered with. CISA's 2026 guidance treats an author signature as an expected element, and as a trusted Certificate Authority, eMudhra enables CertiNext to sign SBOMs with verifiable trust.
CertiNext generates standards-based SBOMs with all required fields, signs them for provenance, maps components to vulnerabilities and licences, and manages versions with full audit trails — turning compliance into a repeatable, automated workflow.
