Third-Party & Vendor Security Assessment.
Know what a supplier touches, what could go wrong and what evidence supports the decision.
A vendor assessment should be proportionate to the service and its access to your systems and information. The work combines inherent risk, evidence review and practical follow-up. It supports onboarding, renewal and remediation decisions without treating every supplier as the same risk.

can cover.
Explore the areas that can shape this engagement. Final coverage follows your systems, priorities and access.
01 / Inside the scope
Service and data mapping
Understand the service, data involved and operational dependencies. Record which systems and locations are relevant to the assessment.
02 / Inside the scope
Inherent risk
Assess impact before considering the supplier’s controls. Use access, criticality and information sensitivity to determine assessment depth.
03 / Inside the scope
Control evidence
Review relevant policies, assurance reports and operating evidence. Distinguish a stated control from evidence that it works for the scoped service.
04 / Inside the scope
Technical exposure
Review relevant hosting, access and testing evidence. Connect technical findings to the service rather than importing unrelated organisation-wide results.
05 / Inside the scope
Contract and exit inputs
Identify security requirements, incident contacts and data-return or deletion expectations for commercial and legal review.
06 / Inside the scope
Residual risk
Document gaps, owners and treatment decisions. Track remediation and reassessment triggers so the decision remains usable after onboarding.

Common questions
What defines the scope?
The systems, business objective and evidence you need determine the scope. The assets, access, deliverables and timetable are agreed before work begins.
What will our team receive?
A clear account of coverage, evidence-backed observations and prioritised next actions. The proposal sets out the exact deliverables and any follow-up review.
Can this fit an upcoming release or audit?
Share the milestone and the systems involved. The assessment can be shaped around that decision once technical fit and availability are confirmed.
