Subject: Clarification of post-quantum readiness response — [product/service]

Dear [supplier contact],

Thank you for your response dated [date] concerning [product/service, version and deployment].

We would appreciate clarification of the following points to complete our information-gathering review. Please answer for the specific product and deployment identified above.

1. Meaning and scope of your claim
Your response states: “[insert the supplier’s exact statement]”.
Please explain what this means in technical terms, including the algorithms, components and uses of cryptography covered, and any exclusions.

2. Availability
Please confirm whether the capability is available in a supported production release, a trial or preview, or remains planned. Which version and configuration does it require?

3. Supporting evidence
Please provide dated technical documentation, release notes or relevant test results supporting the statement. Where an assessment or certification is cited, please identify its scope, date and applicability to our deployment.

4. Delivery dates
Your response refers to “[insert milestone or timing statement]”.
Please provide the target date and distinguish a committed delivery date from an indicative estimate. What conditions or dependencies could affect it?

5. Customer implications
Please clarify the upgrades, configuration changes, testing, costs and operational work required from us. What remains dependent on other suppliers or platforms?

6. Outstanding information
The following questions remain unanswered: [list specific questions].
For each, please state whether the information is unknown, not yet available or cannot be disclosed. Where possible, provide an expected date or a secure route for obtaining it.

We recognise that plans may change. Please identify any uncertainties explicitly and provide the name or role of the technical contact who can discuss them.

We would appreciate your response by [response deadline]. If a full response is not possible by then, please indicate what can be provided and when the remaining information is expected.

Kind regards,
[name]
[role]
[company]

How to review the clarification

Keep the original wording. Record the supplier’s statement alongside its clarification and supporting evidence.
Check the scope. A capability in one component does not establish coverage across the whole product or business.
Separate available features from promises. Record production releases, previews and planned work separately.
Make uncertainty visible. Distinguish unknown information, unavailable evidence and information withheld from disclosure.
Assign next actions. Record who will review evidence, resolve dependencies and follow up outstanding answers.
Seek specialist review where needed. A clearer supplier response does not independently verify its technical claims.

These prompts support further investigation. They do not provide a supplier rating or establish overall post-quantum readiness.
