Blueprint for a Secure Software Supply Chain

Open source libraries make up as much as 80% of modern codebases, and Veracode's 2025 State of Software Security report found that 70% of critical security debt comes from third-party code. Attackers have noticed, planting malicious and typosquatted packages in registries such as npm and PyPI, while regulations including the EU's Digital Operational Resilience Act, in force since January 2025, require organizations to secure their supply chains and produce software bills of materials. This buyer's guide sets out the challenge for executives, security teams and developers, then lists the capabilities an enterprise-grade solution needs: blocking malicious packages before they enter the pipeline, full visibility into direct and transitive dependencies, prioritization by exploitability, CI/CD and repository integration, automated dependency updates and customizable policies. It explains how pairing a package firewall that stops risky packages at download with software composition analysis that finds flaws already in the dependency tree covers both prevention and remediation.
