Security Questionnaire Response — Vendor/Customer

The prompt
I am responding to a security questionnaire from [VENDOR/CUSTOMER NAME]. The question is: "[PASTE QUESTION]"

Using what you know about our Microsoft security environment (Defender XDR, Purview, Entra, Sentinel), draft a factual response to this question.

Requirements:
- Be accurate — do not claim capabilities we haven't confirmed
- Mark any claim that requires manual verification with [VERIFY]
- Keep the response to 2–4 sentences unless the question requires detail
- Use professional, direct language appropriate for a vendor security review

I will review and approve the response before submitting.

How to use it

  1. 1Select Copy the prompt above.
  2. 2Paste it into Microsoft 365 Copilot.
  3. 3Replace anything in brackets with your own detail, then send it.

Copilot gathers and drafts. You verify and decide. Check every figure, name and date against the system it came from before you act on it.
