Cyber insurance underwriters and mid-market prospects are sending more security questionnaires than ever, and UK MSPs are losing deals to them. The security is often fine. The answers are slow, inconsistent or unevidenced. The MSPs that respond well are pulling ahead, fast.
Why are security questionnaires showing up in MSP deals now?
Three years ago, security questionnaires were something only large enterprise clients sent. Today they arrive from mid-market businesses, regulated SMEs, and increasingly from smaller businesses whose insurer has told them to ask. The trigger is almost always the renewal cycle. The underwriter wants to see what the prospect’s MSP is actually doing, and the prospect forwards the form straight to the MSP.
For unprepared MSPs, the form is a deal-killer. The prospect never sees the answer-writing scramble behind the scenes. They see a slow, vague response, and quietly move to the competitor who came back in 48 hours.
Why do unprepared MSPs lose, even when their security is fine?
Four patterns turn up again and again:
- Slow responses signal poor operational readiness, regardless of actual practices
- Inconsistent answers across different questionnaires undermine credibility
- Gaps in documentation expose practices that are sound but unrecorded
- Competitors with answer libraries respond in hours rather than weeks
Prospects judge the security by the response.
What are prospects and their insurers actually checking?
Most questionnaires sent through MSPs cluster around the same controls:
- Privileged access management (who can do what, MFA enforcement, session limits)
- Patch latency (time-to-patch on critical systems)
- Incident response procedures (named owners, runbooks, tested escalation)
- Backup testing frequency (when last verified, what restored)
These are the controls that determine real risk, which is exactly why insurers are asking. An MSP that can answer these clearly with evidence wins the deal. An MSP that cannot, even with sound practices, signals risk.
“Someone else validating what we are, what we do, how we do it.” Nick Haley, Little Big Tech
Independent, current validation means the reviewer checks rather than debates.
How do MSPs that respond well actually do it?
The MSPs winning these deals share three habits:
- They keep a structured answer library. Version-controlled answers to the 30 to 40 questions that turn up in most questionnaires.
- They tie every answer to evidence. A policy doc, a screenshot, a system metric. Every claim sits next to its proof.
- They have one named owner for the response process, so questionnaires do not bounce between technical and commercial people losing context every time.
Together these turn a 2-week scramble into a 48-hour structured response. Sometimes faster.
What is the competitive opportunity here?
Because most MSPs struggle with questionnaires, readiness is a real differentiator. An MSP that responds in 48 hours with structured, consistent answers backed by independently assessed evidence is demonstrably more mature than one that takes 2 weeks and sends a PDF of their policies. The prospect notices.
The faster path is to bring third-party verification into the picture before the questionnaire arrives. A live trustmark, with live-measured controls checked every six hours and the rest on a set cycle, gives the MSP a Trust Portal link to send with the questionnaire, independently assessed, instead of self-asserting on every question. Assurix independently assesses 59 controls: 40 security controls aligned to NCSC CAF 4.0 and 19 operational controls built for MSPs. Leave a failure unfixed for 30 days and the Trustmark is suspended publicly.

Frequently asked questions
Why are insurers driving so much questionnaire volume right now?
Renewal cycles in 2025-26 tightened after a year of high-profile UK incidents. Underwriters are demanding more evidence before renewing or pricing.
Is ISO 27001 enough to skip the questionnaire?
Sometimes, often not. Prospects and insurers increasingly want a current, MSP-specific picture that goes beyond a point-in-time certificate.
How long does an answer library take to build?
About a week of focused work for the first 30 to 40 questions. After that, marginal effort per new questionnaire drops to a couple of hours.
