The Third-Party Risk Landscape

Supply-chain and third-party cyber incidents have become a defining threat vector for organisations across Saudi Arabia and the GCC. Whether through compromised software, insecure APIs, or vendor negligence, attackers routinely exploit trust relationships to breach primary targets. The 2024–2025 threat environment has seen persistent targeting of managed service providers (MSPs), cloud integrators, and payment processors—all critical to regional financial and government sectors.

Under the SAMA Cybersecurity Framework (CSF), financial institutions and designated critical infrastructure operators must now treat third-party risk as a governance mandate, not a compliance checkbox. The National Cybersecurity Authority (NCA) Enterprise Cybersecurity Centre (ECC) guidance reinforces this: vendor and supply-chain risk assessment is a foundational control domain.

Regulatory Expectations in Saudi Arabia

The SAMA CSF explicitly requires organisations to:

  • Conduct documented risk assessments of all third parties with access to systems, data, or networks
  • Establish contractual security requirements aligned with the SAMA CSF and ISO/IEC 27001:2022
  • Implement continuous monitoring and audit rights for critical vendors
  • Maintain an inventory of third-party dependencies and their security posture
  • Define incident response and breach notification protocols for supply-chain events

The Saudi Personal Data Protection Law (PDPL) and its implementing regulations further mandate that data processors and third parties handling personal data must implement equivalent safeguards to those of the data controller. Failure to enforce these contractually and operationally can expose organisations to regulatory enforcement and reputational harm.

Building a Vendor Risk Management Programme

Assessment and Classification: Begin by cataloguing all third parties—software vendors, cloud providers, managed service providers, outsourced functions, and consultants. Classify them by criticality and data access. High-risk vendors (those handling sensitive data, managing critical infrastructure, or with network access) warrant deeper due diligence.

Due Diligence: Request security certifications (ISO/IEC 27001:2022, SOC 2 Type II), conduct security questionnaires, and review audit reports. For critical vendors, consider on-site assessments or third-party security audits. Verify business continuity and incident response capabilities.

Contractual Controls: Embed security requirements into vendor agreements. Specify compliance with SAMA CSF, NCA ECC standards, and PDPL obligations. Include audit rights, breach notification timelines (aligned with PDPL's 72-hour reporting window), and liability clauses for security failures.

Ongoing Monitoring: Vendor risk does not end at contract signature. Implement quarterly or annual reassessments, monitor for security advisories affecting vendor products, and maintain communication channels for incident reporting. Use vulnerability scanning and threat intelligence to track vendor ecosystem changes.

Incident Response: Define escalation paths and testing protocols for supply-chain breaches. Ensure vendors have contractual obligations to notify you within agreed timeframes. Conduct tabletop exercises to validate response readiness.

Practical Priorities for 2026

Security leaders should prioritise vendors handling payment data, personal information, or critical system functions. Cloud service providers, SaaS platforms, and API integrators warrant heightened scrutiny. Establish a risk register, assign ownership, and report progress to the board or audit committee quarterly.

Align vendor risk management with your broader governance framework—SAMA CSF, ISO/IEC 27001:2022, and any sector-specific standards. Document all assessments and remediation actions to demonstrate due diligence to regulators and auditors.

Third-party risk is ultimately a business continuity and reputation issue. Proactive vendor management protects not only your data and systems, but your standing with customers, regulators, and stakeholders across the region.
