TL;DR: CISA’s new Secure Software Development Attestation Form requires CEO or designee certification for software and SaaS developed after September 14, 2022, pushing secure development, trusted supply chains, component provenance, and vulnerability detection into executive accountability, according to OXSecurity. The real change is not paperwork but governance: leaders now have to prove that security controls exist and operate across the software lifecycle, not just assert intent.
Editorial analysis by NHI Mgmt Group, based on content published by OXSecurity: “Think CEOs Are Not Liable for Cyber Risk….Think Again”.
Key questions
Q: What breaks when secure development controls are only applied at release time?
A: Release-only security misses the point where insecure code, secrets and vulnerable dependencies first enter the system.
Q: Why does CEO-level attestation change software supply chain risk management?
A: It forces security, engineering, and compliance to produce evidence that can withstand executive sign-off rather than internal reassurance alone.
Q: Where do secure software attestation programmes fail in practice?
A: They fail when organisations cannot produce evidence that secure development controls actually operated across the pipeline.
Practitioner guidance
- Define a certifiable evidence chain for secure development Map secure environment controls, provenance checks, and vulnerability detection outputs to the specific statements the CEO or designee must certify.
- Assign explicit ownership for attestation evidence Identify who gathers technical evidence, who validates it, and who has authority to sign so responsibility does not stop at engineering.
- Inventory software and SaaS in scope for certification Separate products developed after September 14, 2022 from older offerings and make sure SaaS delivery models are covered in the same governance process.
Bottom line: CISA’s attestation form turns secure development into a leadership-certified governance obligation rather than an engineering-only practice.

Executive attestation is a governance control, not a paperwork exercise. CISA has effectively turned secure development into something leadership must be able to certify, not merely delegate. That matters because software supply chain assurance fails when control ownership is vague or evidence is fragmented. Practitioner conclusion: if leadership cannot trace the control, it cannot credibly sign the attestation.
A question worth separating out:
Q: Who should be accountable for software attestation evidence and why?
A: Accountability should sit with a named certifying executive, but the evidence must come from engineering, security, and compliance together. That structure matters because the attestation is about organisation-wide control integrity, not a single team’s declaration.
