What SaaS Providers Must Implement for Secure Software Development Under NIST SSDF and EO 14028

Executive Order 14028, issued in May 2021, directs federal agencies to require software providers to attest to secure development practices. The National Institute of Standards and Technology responded with the Secure Software Development Framework (SSDF), a structured set of practices for protecting software throughout its development lifecycle. If your company sells software to federal agencies or critical infrastructure operators, leadership is now accountable for demonstrating that specific security practices are in place, documented, and consistently followed.

This is not a technical implementation problem disguised as a compliance exercise. It is a governance question: who decides what constitutes adequate secure development practice, who ensures the organization can attest truthfully, and who maintains the evidence that supports that attestation over time.

What the Framework Requires

The NIST SSDF defines four practice groups that span the software development lifecycle: Prepare the Organization, Protect the Software, Produce Well-Secured Software, and Respond to Vulnerabilities. Each group contains specific practices. For example, under Prepare the Organization, the framework calls for defining security requirements for software development, ensuring personnel understand their roles and responsibilities, and implementing tools to support secure development. Under Protect the Software, practices include protecting software development environments, verifying third-party components, and maintaining provenance for software components.

These are not abstract goals. They are concrete activities that require resources, decisions about acceptable risk, and integration with product development processes. Attestation means a responsible executive certifies that these practices are not merely documented in a policy manual but actively followed.

Why This Matters to the Business

Federal agencies and regulated industries increasingly require attestation before awarding contracts or renewing agreements. Without it, your organization cannot compete for that work. The consequence is not theoretical: contracts are delayed, sales cycles extend, and revenue forecasts become uncertain because leadership cannot quickly answer whether the company meets the standard.

The secondary consequence is internal. Engineering teams continue to build features. Security teams issue recommendations. No single person has the authority or perspective to decide which practices are adequate, what evidence must be retained, or how to resolve conflicts between speed and compliance. The result is fragmented ownership, inconsistent implementation, and attestations that rest on incomplete information.

Who Owns This and What Ownership Looks Like

Attestation is an executive responsibility. It cannot be delegated to engineering, security, or compliance in isolation. The person who signs the attestation—typically the chief executive, chief product officer, or general counsel—must be confident that someone with comprehensive authority has evaluated the organization's practices, identified gaps, prioritized remediation, and established ongoing governance.

Adequate ownership means a single accountable leader who:

• Interprets the SSDF practices in the context of your specific development environment and risk profile
• Defines what constitutes sufficient evidence for each practice
• Coordinates across engineering, security, legal, and compliance to implement required controls
• Maintains a current assessment of which practices are in place, which have gaps, and what the timeline is for closing them
• Advises the attesting executive on what can truthfully be certified and what cannot

This is the function of a chief information security officer. In organizations that lack a full-time CISO or where the security leader reports through IT or engineering, the required authority and cross-functional perspective may not exist. Heights provides [virtual CISO (vCISO) leadership](/vciso/) to establish this governance structure without the overhead of a permanent executive hire.

Practical Implementation Sequence

Implementation does not begin with technology. It begins with assessment. Leadership must understand the current state: which SSDF practices are already in place, which exist but lack documentation, and which represent genuine gaps. This assessment produces a prioritized list of actions, each with a responsible owner and a timeline.

The second step is to establish governance for ongoing compliance. Security practices degrade without active oversight. New developers join, build processes change, third-party components are introduced. Governance means regular review, evidence collection, and a mechanism for detecting and correcting drift before attestation becomes inaccurate.

The third step is to integrate attestation readiness into product planning. SSDF compliance is not a one-time project. It is an ongoing requirement that must be factored into release cycles, vendor evaluations, and hiring plans. Without this integration, compliance becomes a bottleneck that delays every federal opportunity.

How This Relates to Broader Framework Readiness

The SSDF is one of several frameworks that regulators and customers now expect organizations to adopt. NIST also publishes the Cybersecurity Framework, which provides a broader structure for managing cybersecurity risk across the enterprise. The supplied sources indicate that NIST has developed tools to map relationships between its frameworks, including how specific practices in one framework correspond to outcomes in another.

For leadership, the question is not whether to comply with each framework in isolation but how to establish governance that addresses common requirements efficiently. A vCISO provides this strategic perspective, ensuring that work done to meet SSDF requirements also advances broader cybersecurity maturity and prepares the organization for related regulatory expectations.

What Leadership Should Do Next

First, determine whether anyone in the organization currently has the authority and cross-functional visibility to assess SSDF readiness and maintain ongoing compliance governance. If the answer is unclear or if responsibility is distributed across multiple people without a single decision-maker, that is the gap that must be closed before technical work begins.

Second, conduct a baseline assessment of current secure development practices against the SSDF framework. This assessment should identify not only what is missing but also what exists without adequate documentation or evidence. The output is a prioritized action plan with specific owners and timelines.

Third, establish a governance process for maintaining compliance. This includes regular reviews, evidence collection, and a mechanism for the attesting executive to receive accurate, current information about the state of compliance before signing any attestation.

Heights Consulting Group works with software providers and SaaS companies to establish the executive-level governance that makes attestation possible. If your organization is facing attestation requirements without clear ownership or a structured approach, a confidential consultation will clarify your current position, the specific gaps that must be addressed, and the governance structure required to maintain compliance over time. This is offered once, at the point where leadership must decide how to proceed.
