Why You Need This
When an enterprise prospect sends a vendor security questionnaire, your senior engineers face 20–40 hours of work answering 50–200 detailed questions about information security policies, access controls, encryption, incident response, backup and recovery, vendor risk management, and personnel security.
Done internally:
- 2–4 weeks of senior engineering time lost
- Risk of over-stating controls (future claim risk)
- Risk of under-stating controls (losing the deal)
- Inconsistency with previous questionnaires
- Inputs required from CTO, CISO, legal, and operations
Done with Optimum:
- Fixed price, fixed timeline
- Accurate answers backed by evidence
- Consistent with previous questionnaires
- Defended through clarification rounds
- Engineering team stays focused on product

Frequently Asked Questions
How is this different from Compliance-as-a-Service (€729/month)?
Compliance-as-a-Service is a recurring monthly subscription that includes ongoing compliance work including questionnaire responses up to a monthly cap. The Vendor Security Questionnaire service is a one-off, pay-per-questionnaire model — better if you have occasional questionnaires and don't need recurring services. If you're handling more than 3 questionnaires per quarter, Compliance-as-a-Service is more cost-effective.
Can you commit to answers you can't verify?
No. Every answer is supported by evidence you provide. Where we can't substantiate an answer, we mark it for your review and recommend either remediation (so you can answer truthfully "yes") or disclosure (answer truthfully "no" or "partially"). We never invent capabilities you don't have — that creates future claim exposure for you.
What if the prospect's questionnaire has a deadline of 48 hours?
Rush service available at +50% premium with same-day NDA signing. Contact us directly for urgent timelines. Standard delivery is 5–10 business days.
Can you submit on our letterhead?
Yes. We can prepare the questionnaire as if it were filled out by your team (using your letterhead, your representative's name with your explicit authorisation). Alternatively, we can disclose our involvement to the prospect — many enterprise prospects view this positively as evidence of professional security engagement. Your choice.
Do you keep our answers and supporting evidence after delivery?
We retain copies for 12 months solely for follow-up clarification rounds, then destroy them. Documents are held in encrypted storage. Destruction certificate available on request.
What questionnaire formats do you handle?
All major industry-standard formats (SIG Lite, SIG Core, CAIQ, VSAQ) plus custom enterprise procurement forms. If you have an unusual format, send it to us first — we'll confirm fit and pricing within 24 hours.
Can you build us a reusable questionnaire response template?
Yes. As an add-on (+€500), we deliver a standardised internal answer library and evidence index that your team can use for future questionnaires — reducing the cost of subsequent questionnaires by 50–70%.
