Supply Chain Risk
Your security is only as strong as your weakest vendor. We help you assess, prioritise, and continuously manage third-party and supply chain risk.
Your Risk Extends Beyond Your Perimeter
Some of the most damaging breaches of recent years did not start inside the victim's network - they arrived through a trusted supplier. Your attack surface now includes every vendor, platform, and sub-processor you depend on.
Hidden exposure in third-party relationships has become a board-level concern and a due-diligence red flag. Enterprise buyers and investors increasingly expect evidence that you understand and manage the risk your supply chain carries.
Our fractional CISOs bring structure to third-party risk - assessing suppliers, focusing effort on the ones that matter, and building an assurance process that keeps pace with new relationships and new regulation.
When You Need This
- You have no clear inventory of your vendors and their access
- Supplier security is reviewed inconsistently, if at all
- A key supplier suffered an incident that affected you
- Customers or investors are asking about third-party risk
- You need to meet NIS2, DORA, or ISO 27001 supplier requirements
- You depend heavily on a small number of critical vendors
- Procurement moves faster than security can assess
Supply Chain Risk Services
Structured third-party risk management, from first assessment to continuous assurance
Third-Party Risk Assessment
Assess the security posture of your vendors and partners, exposing the hidden exposure that third-party relationships introduce into your environment.
Vendor Due Diligence
Run consistent, proportionate due diligence on new and existing suppliers - from lightweight questionnaires to deep review for your most critical vendors.
Supplier Tiering & Criticality
Map and tier suppliers by criticality, data access, and business impact, so effort is focused where a compromise would hurt you most.
Contractual Security Requirements
Define the security clauses, SLAs, and right-to-audit provisions that should sit in every supplier contract, and embed them into procurement.
Continuous Monitoring
Move beyond point-in-time assessments with ongoing monitoring of supplier risk, breach notifications, and changes in their security posture.
Fourth-Party & Concentration Risk
Understand the dependencies behind your dependencies - the shared platforms and sub-processors that create systemic, concentrated risk.
Clear visibility of the risk your suppliers introduce
Faster, more consistent vendor onboarding
Evidence for customer and investor due diligence
Reduced exposure to supply chain and third-party attacks
Alignment with NIS2, DORA, and ISO 27001 supplier controls

The Benefits of Managed Supply Chain Risk
Organisations that manage third-party risk well onboard suppliers faster, pass customer security reviews more easily, and are far less likely to be caught out by a vendor's breach.
