That is a plausible explanation for how the process can go wrong—not proof that security buyers generally or deliberately prefer appearances over risk reduction.
How assurance can turn into box-ticking
A buyer can record that a questionnaire was completed or a certificate supplied. But those artifacts do not, on their own, establish whether a vendor’s controls fit the planned use, whether its claims are reliable, or whether a discovered weakness should change approval or contract terms. Interpreting evidence and acting on it take more work than collecting it.

One public-sector audit illustrates the gap. The Queensland Audit Office reviewed three entities: all three used supplier risk questionnaires, but only one assessed the answers to understand supplier risk. In a separate review of 36 contracts, just two required suppliers to report cybersecurity incidents and vulnerabilities. These findings describe the audited entities and contracts, not the market as a whole. (Queensland Audit Office)

The distinction is not that questionnaires or certificates are useless. They can organize evidence and set a baseline. The problem is treating completion or possession as the result, rather than asking what the evidence means for this supplier and purchase.

Why the signals can be attractive—and what the evidence shows
Visible artifacts offer an administratively convenient record: a step was requested, received, and filed. UK procurement guidance instead calls for security questions and evaluation weight to reflect the procurement and its risks, including the sensitivity of personal information involved. NIST likewise describes due diligence as investigating pertinent supplier or product information so decisions are informed. Together, these sources support an explanation based on process incentives and workload; they do not measure how often buyers choose theater or establish a universal motive. (UK Department for Science, Innovation and Technology; NIST SP 1326)
In its response to a consultation on supply-chain cybersecurity, the UK government recorded lack of incentive to invest as a significant barrier and said senior management and boards have responsibility for prioritizing investment. That points to an accountability challenge, not proof that buyers consciously reward symbolic compliance or that one incentive dominates across organizations. (UK government response)
What substantive supplier due diligence covers
NIST SP 1326, a final guide published in July 2026, identifies five components relevant to ICT supplier due diligence. They help explain why a single certificate or self-description cannot answer every risk question:

- Provenance: examine where products and components come from.
- Resilience: consider whether the supplier and its products can withstand disruption.
- Foundational cybersecurity practices: examine the supplier’s underlying security practices, not just its assurances about them.
- Supply-chain tiers: account for relevant dependencies beyond the direct supplier.
NIST’s definition captures the purpose: “Due diligence research is the investigative process of researching all available, pertinent information about a given supplier or product so that informed decisions can be made on new acquisitions or existing systems.” The key words are “pertinent information” and “informed decisions”: due diligence is meant to affect a decision, not merely produce paperwork. (NIST SP 1326)

How to judge whether an assurance process is real
Use these questions to assess whether a buyer is evaluating risk or mostly recording compliance:
- Risk relevance: Does the review reflect the data, access, service, and potential consequences involved in this purchase? UK guidance says security questions and their evaluation weight can vary with procurement context and risk. (UK guidance)
- Evidence quality: Does someone examine pertinent information and the supplier’s practices, or is self-attestation accepted as the conclusion? NIST’s definition of due diligence centers on investigation to inform decisions. (NIST SP 1326)
- Decision consequence: Can findings change the shortlist, approval, mitigation plan, or terms? The Queensland audit’s questionnaire finding shows why collecting answers without consistently assessing them is insufficient. (Queensland Audit Office)
- Contract accountability: Are supplier expectations and suitable obligations—such as incident and vulnerability reporting—written into the contract? The Queensland Audit Office recommends clear expectations and appropriate clauses. (Queensland Audit Office)
- Lifecycle follow-through: Does anyone monitor the supplier after purchase and revisit whether the risk and mitigation remain appropriate? The same audit recommends ongoing monitoring. (Queensland Audit Office)
A practical sequence for buyers
- Map the exposure. Identify the supplier, what the purchase will do, what data or access it will involve, and relevant supply-chain dependencies.
- Scale the review to the risk. Ask questions and evaluate evidence in proportion to the purchase, considering its context rather than applying a gate without interpretation.
- Make findings consequential. Decide whether gaps require mitigation, affect approval, or change the choice of supplier.
- Put expectations in the contract. Document obligations, including appropriate incident and vulnerability reporting, and establish suitable accountability mechanisms.
- Monitor over time. Check whether controls and mitigations remain appropriate as the supplier relationship and circumstances change.
This sequence connects supplier identification and evidence review to decisions, contract obligations, and continuing oversight—the parts a completed form alone cannot provide. It reflects the due-diligence components in NIST SP 1326 and recommendations from the Queensland Audit Office. (NIST SP 1326; Queensland Audit Office)

The available evidence does not show how often security buyers reward theater, whether it is deliberate, or which incentive dominates across public and private organizations. The Queensland findings come from three selected public-sector entities and a 36-contract sample; UK government material includes consultation findings and guidance; NIST provides a due-diligence framework. These sources support a process-level warning, not a prevalence estimate or a claim about buyer motives in general.
