Government was the forcing function for modern software supply chain security. After a series of high-profile compromises, Executive Order 14028 in May 2021 set out to change how the federal government buys and builds software, and the requirements that followed have reshaped the market for anyone who sells to a public-sector buyer. In 2026, secure software development is no longer a differentiator when bidding on government work. It is a precondition, backed by attestations that carry legal weight.
The regulatory drivers
Executive Order 14028 directed the creation of secure software development standards, which NIST delivered as the Secure Software Development Framework, SP 800-218 (the SSDF). The Office of Management and Budget then turned the framework into a procurement requirement. OMB Memorandum M-22-18, reinforced by M-23-16, requires federal agencies to obtain a self-attestation from software producers confirming that their development practices conform to the SSDF, with an SBOM or other artifacts available on request. CISA published a common Secure Software Development Attestation Form to standardize how producers make that attestation, and a signed attestation is a representation the government can hold a vendor to.
For cloud services, FedRAMP remains the gate. Its authorization baselines are aligned to NIST SP 800-53, and the program's ongoing modernization has pushed toward more automated, continuous evidence rather than point-in-time paperwork. Where contractors handle controlled unclassified information on their own systems, NIST SP 800-171 sets the protection requirements. The connective tissue across all of these is the same expectation: know your components, develop them securely, and be able to prove both.
What a government program needs
Whether you are an agency securing what you build and operate or a vendor selling into government, the program requirements converge.
You need an accurate, continuously updated inventory of every component in every application, because an SBOM you cannot regenerate on demand is not evidence, it is a stale snapshot. You need development practices that map cleanly to the SSDF's practice areas, from provenance and integrity to vulnerability management, so that your attestation is defensible rather than aspirational. You need prioritization grounded in real exposure, because agency and contractor teams are as resource-constrained as anyone and cannot chase every low-risk finding. And you need evidence that maps to NIST 800-53 and 800-171 controls without a manual assembly effort each assessment cycle.
Practical controls
Generate a signed SBOM for every build and retain it as a release artifact, so the "available on request" clause of the OMB memoranda is something you can satisfy in minutes. Establish provenance for your build pipeline, pin CI/CD actions to immutable hashes, and move to short-lived, scoped credentials so a stolen token cannot be replayed. Enforce policy gates that block a release containing a known-exploited or malicious component, and document the practice so it maps to an SSDF task.
Route vulnerability findings through reachability analysis before they reach an engineer, so remediation effort concentrates on code that actually runs. Keep your control evidence continuously current rather than reconstructing it for each 800-53 or 800-171 assessment. And treat internet-facing infrastructure as assume-breach, with segmentation and monitoring, because edge appliances remain a favored initial-access route.
How Safeguard helps
Safeguard operationalizes the SSDF and the attestation regime instead of leaving them as documents. Our software composition analysis inventories every direct and transitive dependency and applies reachability analysis, so the vulnerability picture you attest to reflects genuine exposure rather than a raw count. That precision matters when a signed attestation is a representation to the federal government.
SBOM Studio generates, signs, and version-controls SBOMs and AIBOMs, so the artifact behind your OMB attestation regenerates on every build and never goes stale. When remediation is needed, Griffin AI generates and validates the fix and opens it as a reviewable pull request, keeping a human in the approval loop while compressing the time from disclosure to patch.
For assessments, the compliance module maps findings and controls to NIST SSDF, SP 800-53, and SP 800-171 and exports evidence packages, so preparing for a FedRAMP assessment or a contract review becomes a query rather than a project. And because government workloads frequently run in isolated, classified, or sovereign enclaves, Safeguard deploys as SaaS, self-hosted, or fully air-gapped, so code and findings never leave an accredited boundary.
Selling to or securing government means proving your software supply chain, not just asserting it. See how the pieces fit your mission on the solutions overview, or start a free trial.
Frequently Asked Questions
What does the CISA attestation form actually require? The Secure Software Development Attestation Form asks a software producer to attest that its development practices conform to specified elements of the NIST SSDF, signed by a responsible official. It is a standardized way for agencies to collect the self-attestation OMB requires, and because it is a formal representation, the underlying practices and artifacts need to be real and reproducible.
Do we need an SBOM even if the attestation is self-attested? The OMB memoranda allow agencies to require an SBOM or other artifacts in addition to the attestation, and many do. Practically, generating a signed SBOM on every build is the cleanest way to satisfy that request and to back up the vulnerability-management claims in your attestation.
How does Safeguard map to NIST SSDF and 800-53? Safeguard's compliance module associates findings, policy-gate results, and remediation records with SSDF practices and with SP 800-53 and 800-171 controls, then exports that as evidence. This turns framework mapping into a maintained data set rather than a spreadsheet you rebuild each assessment.
Can Safeguard run in a classified or air-gapped enclave? Yes. Safeguard supports fully air-gapped and self-hosted deployment in addition to SaaS, so it can operate inside isolated, sovereign, or accredited environments without external connectivity, keeping source and findings within the boundary.
