Pass Any Enterprise Vendor Security Assessment
An enterprise client wants to work with you — then their security team sends a 300-question spreadsheet. We get UK agencies and suppliers through supplier security reviews so the deal closes.
The Security Questionnaire Is Where Enterprise Deals Die
Winning enterprise work as an SMB used to be about the pitch. Now procurement won't issue a contract until their security team signs you off. The questionnaire arrives — SIG, CAIQ, or a custom spreadsheet — and suddenly you're being asked for information security policies, incident response plans, and evidence of controls you've never had to write down.
Deals stall for months
Every unanswered follow-up round adds weeks. Momentum dies and champions move on.
Honest answers look bad
Without preparation, truthful answers expose gaps — MFA, backups, policies — that trigger a fail.
Nobody owns it internally
The questionnaire lands on a founder or ops lead who has a business to run, not a security function.
Competitors who pass, win
Enterprises increasingly shortlist only suppliers who clear security review quickly.
What Enterprise Assessments Actually Ask For
Across Microsoft-scale tech platforms, global consumer brands and regulated enterprises, the same control families come up every time. If you can evidence these, you pass.

From Questionnaire to Signed Contract
Rapid Gap Review
We map the questionnaire (or a standard one, if you're preparing proactively) against your actual controls and identify exactly what would fail.
Fix the Gaps That Matter
We implement the missing controls — MFA, device management, policies, backups — prioritised by what reviewers actually check, not a 200-item wish list.
Build Your Evidence Pack
Policies, screenshots, configurations and attestations organised so every answer has proof attached. This pack is reusable for every future assessment.
Answer & Submission Support
We draft accurate, well-framed answers with you and handle the follow-up rounds with the client's security team until you're approved.
Stay Assessment-Ready
Annual re-assessments arrive fast. As your ongoing IT and security partner, we keep controls and evidence current so renewals take days, not weeks.
Proven Against Real Enterprise Security Teams
Five enterprise vendor assessments passed, zero deals lost
A London creative agency kept winning pitches with household-name enterprise clients — then hitting their supplier security reviews with no dedicated IT or security function. We built their security baseline, assembled a reusable evidence pack, and managed each assessment through to approval.
The agency has now passed security assessments from five global enterprises — including a global technology platform, a global social media platform and a global sportswear brand — without losing a single engagement to security review.

A Route Into Certification

Vendor Security Assessment FAQs
Before an enterprise signs a supplier, its security team reviews how that supplier protects data — usually via a questionnaire (often 100-400 questions), evidence requests and sometimes a call with your team. Passing it is a condition of the contract; failing or stalling usually means the deal goes to a competitor who can pass.
With the right preparation, most SMBs can complete a questionnaire credibly within 2-4 weeks. The biggest delays come from missing basics — no written policies, no MFA enforcement, no documented incident response plan. We fix those gaps first, then answer with evidence.
Usually not. Most enterprise assessments accept well-evidenced controls without formal certification, especially for smaller suppliers. Certifications like Cyber Essentials, ISO 27001 or SOC 2 shorten the process and reduce follow-up questions — and if one is genuinely required, we run that certification process for you too.
Yes — but honestly. We draft the answers with you based on controls you actually have, fix the gaps that would cause a failure, and build the evidence pack reviewers ask for. Fabricated answers get caught at the evidence or audit stage and kill the deal permanently.
Yes — this is the most common way clients find us. Send it over and we'll triage it within 48 hours: what you can answer today, what needs fixing first, and a realistic plan to submit before the deadline.
Assessment support is scoped as a fixed-fee engagement based on the questionnaire size and your current security maturity — no open-ended day rates. Related certifications (Cyber Essentials, ISO 27001 readiness) are available as fixed-price packages on our pricing page.
