Supply-chain security
Third-Party Cybersecurity Risk Audit
Determine whether suppliers with access to systems, data and critical services receive security oversight proportionate to the risk they introduce.
The business problem
Why this assessment matters.
Questionnaires alone do not reveal whether the highest-risk providers were identified, evidence was challenged, contract requirements were enforced or material changes triggered reassessment.
Our audit evaluates the full third-party lifecycle and samples real vendor files. It connects inherent risk, due diligence, agreements, findings, monitoring and termination into one defensible control story.
Audit coverage
What we assess.
Final scope reflects your environment, critical systems, risk profile and assurance objective.
Vendor inventory completeness and ownership
Inherent-risk tiering and criticality
Security questionnaires and evidence review
SOC reports, certifications and penetration evidence
Contract security, notification and audit rights
Fourth-party and concentration risk
Continuous monitoring and material-change triggers
Findings, exceptions, offboarding and data return
Assessment process
How the audit works.
Testing is evidence-led, risk-based and designed to protect business operations.
- Define the vendor population and priority risk segments
- Review program standards and workflow configuration
- Sample vendors across tiers and lifecycle stages
- Trace findings into contracts, remediation and acceptance
- Recommend scalable review depth and monitoring triggers

Frequently asked questions
Planning your third-party cybersecurity assessment.
Will you contact our vendors?
Only when explicitly included. Most audits begin with your inventory, evidence, contracts and workflow records.
How many vendor files are sampled?
The sample is risk-based and spans tiers, service types, lifecycle stages and known exceptions.
Can you review SOC 2 reports?
Yes. We evaluate scope, period, exceptions, complementary controls and relevance to the service received.
Does the audit cover contract language?
We assess whether defined security provisions appear and operate; qualified counsel should make final legal determinations.
Can this include fourth-party risk?
Yes. We review subcontractor transparency, concentration dependencies and how critical downstream providers are monitored.
