OSPO and SBOM: How Open Source Program Offices Are Evolving Into Supply Chain Security Centers

The Traditional OSPO Mandate

Traditional OSPOs manage: inbound open source policy (what licenses are approved for use), outbound open source policy (what the company can contribute and release), license compliance (attribution, copyleft obligations, distribution compliance), and community engagement (managing the company's participation in open source projects). Companies like Google, Microsoft, and Red Hat have had OSPOs for decades. The post-EO-14028 wave of compliance requirements has prompted many organizations to establish OSPOs for the first time.

The SBOM Expansion

SBOM programs naturally align with the OSPO because they involve the same organizations that inbound open source policy governs: the collection of third-party and open source components used in products. In organizations that have added SBOMs to the OSPO mandate, the function now: owns SBOM tooling selection and deployment; manages the company's SBOM policy (what must be inventoried, how fresh SBOMs must be); interfaces with procurement teams on vendor SBOM requirements; and responds to customer SBOM requests. This expanded mandate positions the OSPO as the organizational hub for supply chain security transparency.

Metrics and Reporting

OSPOs with expanded SBOM mandates report upward to CISO and sometimes directly to the board on supply chain security metrics: SBOM coverage percentage, license policy compliance rate, mean time to update critical components, and regulatory compliance status across frameworks. This visibility gives the security dimensions of open source governance executive attention that license compliance alone rarely received.

Building an SBOM-Capable OSPO

Organizations building or expanding OSPOs to include SBOM responsibilities need: tooling integration (SCA platform connected to CI/CD pipelines), policy infrastructure (documented license and component selection policies enforced in tooling), and cross-functional relationships (with development teams, security, procurement, and legal). The SBOM serves as both the operational artifact and the communication mechanism that connects these different organizational stakeholders to a shared view of supply chain risk.
