What it means
Requests for information and proposals should give vendors testable requirements and disclose the evidence needed for selection, implementation, audit, incident response, continuity, and exit.
Why it matters
Security added after selection has less leverage, higher cost, and more dependency on vendor goodwill.
Practical focus
- Translate risk into measurable acquisition requirements
- Evaluate architecture, operations, evidence, and supplier dependencies
- Include incident, audit, continuity, data return, and exit rights
- Verify commitments during acceptance and throughout the relationship
Common mistakes
- Selecting on questionnaires alone
- Using vague language such as industry standard
- Ignoring subcontractors and software supply chains
- Negotiating exit and data return only after termination
