How to Answer an Enterprise Security Questionnaire
This guide is for founders and executives at growing companies who just received a long security questionnaire from an enterprise prospect. The fastest way through is to answer honestly, keep your answers in one reusable library, and have a credible security leader available for the follow-up call. Never claim a control you do not have. A false yes will cost you more later than an honest no costs you now.
What are these questionnaires, and why are they showing up now?
Large companies assess the security of every vendor that touches their data. Two standard formats appear often. The SIG (Standardized Information Gathering questionnaire) is published by Shared Assessments. The CAIQ (Consensus Assessments Initiative Questionnaire) is published by the Cloud Security Alliance and maps to its Cloud Controls Matrix. Many buyers also send their own spreadsheet.
They usually arrive late in the sales cycle, when procurement gets involved. That timing is why they feel urgent. A deal that looked closed can wait weeks on a questionnaire nobody owns.
Who should own the answers?
One named person. That person does not have to know every answer, but they must know who does, and they must sign off on what goes out. Sales should not fill these in alone. The answers describe how your company operates, and a well-meant guess from someone outside security is still a guess.
How do you answer a control you do not have?
Say so, then say what you do instead. A good answer to a missing control has three parts: the honest status, any compensating control that reduces the same risk, and a date if the control is on your roadmap. For example: "We do not yet have a SIEM (a central system for monitoring security logs). Logs from production systems are retained and reviewed weekly. Centralized monitoring is planned for next quarter."
Buyers see partial answers every day. What damages trust is discovering that a yes was false. Questionnaire answers are often relied on in vendor reviews and can be referenced in contracts, so an overstated control can become a legal and commercial problem, especially after an incident. If you are unsure whether an answer is true, treat it as a no until someone verifies it.
How do you make the next questionnaire faster?
Treat the first one as an investment. Save every approved answer in a single library, with the owner and the date it was last checked. Most questions repeat across questionnaires with different wording.
Then build a small set of documents you can share on request: a security overview, your key policies, a summary of your latest penetration test, and a SOC 2 report if you have one, usually under NDA. Many buyers will read these first and may accept them in place of some sections. Update the library whenever a control changes, so it never drifts from reality.
What happens on the follow-up call?
For a meaningful deal, the buyer's security team will often ask for a call. This is where deals are won or lost. They want to talk to someone who can explain how your controls work without reading from the spreadsheet.
Put a credible voice on that call: someone with real security experience who can speak plainly, admit gaps, and describe the plan to close them. "I don't know, I will confirm by Thursday" builds more trust than a confident guess. If nobody on your team can play that role, that is a sign you need senior security help, at least part time.
What should you never do?
Do not copy answers from another company's questionnaire. Do not answer yes to something you plan to do next quarter. Do not attach a policy that was written last week and never adopted. And do not let a deadline push you into any of the above. Asking the buyer for a few more days is normal.
Takeaway: an honest "no, and here is our plan" keeps deals alive, and a false "yes" puts them at risk.
