Case Study: Strengthening Third-Party Security Risk Management for a Public Services Organisation

Background

A major public services institution in the UK engaged our services to enhance their Third-Party Security Risk Management capabilities. With an expanding digital ecosystem and increasing reliance on third-party vendors, the client recognized the critical need for a structured and proactive approach to managing supply chain security risks.

The Challenge

The organization faced several key challenges, including:

• Inconsistent third-party risk assessment processes
• Limited visibility into third-party security postures
• Lack of centralized reporting on key security metrics
• Need to align third-party governance with internal policies and regulatory requirements

The Solution

We deployed an experienced Third-Party Security Risk Manager with a strong background in technical security assessments, risk governance, and regulatory compliance. Our structured approach included:

Phase 1: Third-Party Risk Assessment and Mitigation

• Conducted detailed technical security assessments for new and existing third-party vendors
• Identified security gaps and developed tailored risk mitigation plans
• Ensured timely follow-up and tracking of remediation actions

Phase 2: Framework Enhancement

• Strengthened the third-party risk management framework by introducing standardized assessment criteria, risk rating methodologies, and escalation procedures
• Integrated security requirements into the vendor onboarding and renewal processes

Phase 3: Metrics, Reporting, and Monitoring

• Developed dynamic dashboards and executive-level reports to track key performance indicators (KPIs) and key risk indicators (KRIs)
• Provided real-time insights into third-party risk exposure, enabling better decision-making and prioritization

Phase 4: Stakeholder Collaboration

• Worked closely with internal stakeholders (procurement, legal, compliance, IT) to align security risk management activities
• Engaged with third-party vendors to improve their security postures and ensure compliance with contractual obligations

Through our partnership, the client achieved significant results, including:

• Improved risk visibility through detailed technical assessments and dashboard reporting
• A formalized and standardized third-party risk management framework embedded across procurement and security processes
• Proactive risk management through early identification and mitigation of vendor security risks
• Strengthened compliance posture in line with regional regulations and internal security standards

Expected Benefits

The implementation of the enhanced Third-Party Security Risk Management framework was expected to provide numerous benefits, including:

• Improved risk visibility and management
• Enhanced compliance with regulatory requirements
• Strengthened security posture of third-party vendors
• Better decision-making and prioritization through real-time insights

Conclusion

Our expertise and guidance enabled the public services institution to strengthen its Third-Party Security Risk Management capabilities, reducing the organization’s overall exposure to supply chain security risks. Our partnership has had a lasting impact on the client’s ability to manage third-party risks and protect its sensitive assets.
