Vendor Security Questionnaire Response Desk for B2B Sellers

The problem

B2B vendors selling to enterprises get hit with long, repetitive security and due-diligence questionnaires that stall deals for weeks. Answering them pulls engineers, security leads, and founders off their real work, and inconsistent answers across submissions create risk. Small sellers have no dedicated team to handle the volume, so revenue sits waiting on a spreadsheet.

Why now

Enterprise procurement has tightened security scrutiny, so questionnaires now hit sellers of every size, while LLMs can draft accurate answers from a maintained knowledge base and match new questions to prior ones. This lets a small desk turn questionnaires around fast and consistently, and sellers are motivated because a stalled questionnaire directly delays revenue.

Who pays

Founders, sales leaders, and security leads at 10 to 300 employee B2B software and services companies in the US, UK, CA, and AU that sell to enterprise and mid-market buyers with formal vendor-review processes.

How it makes money

Recurring retainer from $1,500 to $5,000 per month by questionnaire volume, plus per-questionnaire rush fees, and an onboarding fee of $2,000 to $6,000 to build the client's security answer library and profile from their policies and controls.

Market & demand

Order-of-magnitude: hundreds of thousands of B2B sellers across the four markets face vendor-security reviews; even 80 to 150 retainers at an average of ~$2,800 per month is a healthy seven-figure ARR desk.

Third-party risk management is expanding and security questionnaires are proliferating across deal sizes, turning them into a routine sales bottleneck. Answer-automation tooling is maturing, but many sellers still need someone to own the process, favoring a managed desk over a tool they must staff.

SWOT

Competition & the gap

Questionnaire-automation tools like Loopio and Whistic, trust-center products from Vanta and SafeBase, and in-house or freelance security writers.

The wedge: A managed desk that owns the whole questionnaire workflow with a maintained, accurate answer library, for sellers who want the bottleneck gone rather than another tool to run themselves.
