As the software landscape becomes increasingly complex and interconnected, enterprises face growing challenges in securing their applications and infrastructure. With the widespread use of open-source libraries, third-party components, containerised deployments, and microservices, organisations are often unaware of what truly resides in their codebases. This visibility gap creates fertile ground for security vulnerabilities to go undetected until it’s too late.
Enter the Software Bill of Materials, or SBOM. In the same way that manufacturers track every part that goes into a product, an SBOM provides a detailed inventory of all software components, whether developed in-house or sourced externally. In today’s threat landscape, SBOMs are rapidly becoming a foundational element of enterprise security strategies.
What is an SBOM?
An SBOM is a machine-readable document that itemises the components of a given software product, including dependencies, libraries, licenses, and their respective versions. It can include metadata such as supplier name, component version, unique identifiers, and relationships between components.
This “ingredient list” gives teams a clear view of what code their software is built on. As a result, organisations can quickly assess security risks, license compliance issues, and potential vulnerabilities within their software supply chain.
SBOMs are typically generated during the software build process and can be integrated into CI/CD pipelines for continuous updates. Common formats include Cyclonedx, SPDX, and SWID, all of which promote interoperability and standardisation across tools and organisations.
Why SBOMs are Critical to Enterprise Security
1. Supply Chain Security is Now a Boardroom Concern
High-profile supply chain attacks such as SolarWinds, Log4Shell, and MOVEit have shown how attackers exploit vulnerabilities in dependencies or development pipelines to compromise software downstream. These incidents didn’t just affect IT departments, they made headlines, triggered regulatory responses, and caused substantial reputational and financial damage.
An SBOM allows enterprises to identify and understand third-party risks. When a new vulnerability is disclosed, security teams can quickly query the SBOM to determine whether and where the vulnerable component is present in their environment. This drastically reduces response times during zero-day scenarios.
2. Compliance and Regulatory Pressure are Growing
Governments and industry regulators are beginning to mandate the use of SBOMs. For example, Executive Order 14028 in the United States directs software vendors to provide SBOMs for products used by federal agencies. Similarly, the EU’s Cyber Resilience Act and ISO/IEC 5230 (OpenChain) promote software transparency and secure development practices.
For enterprises operating in regulated industries such as finance, healthcare, and defence, implementing SBOMs is becoming a compliance necessity rather than an option.
3. Improved Vulnerability Management and Response
Traditional vulnerability scans often fail in dynamic environments, particularly where containers or microservices are regularly spun up and down. SBOMs offer a more comprehensive and persistent view of software dependencies.
With tools like Grype, Anchore, and Snyk, enterprises can automate the scanning of SBOMs against known vulnerability databases (e.g., NVD or GitHub Advisory Database). This ensures that teams are proactively identifying outdated or vulnerable packages, not just reacting when threats materialise.
From “Shift Left” to “Build Securely from the Start”
SBOMs play a crucial role in modern DevSecOps strategies. By integrating SBOM generation into build pipelines, developers can gain visibility into risky components before they are deployed. This supports a “shift-left” security model, where issues are identified early, reducing costs and accelerating remediation.
Moreover, SBOMs support:
- License management – preventing legal issues from incompatible or non-compliant open-source licenses.
- Dependency hygiene – flagging deprecated or abandoned packages that could introduce security gaps.
- Audit trails – enabling post-incident forensics by showing which versions were used at a given point in time.
Challenges in Adopting SBOMs
Despite their advantages, SBOMs are not without implementation hurdles. Some of the most common include:
- Tooling fragmentation – not all SBOM formats are compatible with all scanners or orchestration tools.
- Incomplete component data – particularly in legacy systems or closed-source packages.
- Data overload – large applications may include thousands of dependencies, overwhelming teams without proper triage mechanisms.
Enterprises must approach SBOM adoption with a strategic plan, selecting standardised formats, integrating with CI/CD tools, and establishing governance for ongoing maintenance.
Looking Ahead: The Future of Software Transparency
The SBOM movement is part of a broader trend toward software transparency and trust. As zero-trust architectures become the norm, knowing what software you’re running and who built it is essential to enforcing secure policies.
Looking forward, we can expect:
- Greater automation – SBOMs are generated and validated automatically across the software lifecycle.
- Wider integration – SBOMs are being used for procurement decisions, risk scoring, and supply chain certification.
- Policy enforcement – platforms blocking deployments with known vulnerabilities or unapproved components.
After all, security is no longer just about perimeter defences, it’s about knowing your systems inside and out.
Conclusion
Software Bills of Materials will be foundational to enterprise cybersecurity in 2025 and beyond. By offering visibility into the components that underpin applications, SBOMs empower organisations to respond faster to vulnerabilities, meet regulatory demands, and build trust with stakeholders.
For enterprises looking to harden their software supply chain, SBOMs are not just a best practice, they’re a critical safeguard in an increasingly complex digital ecosystem.
