The incident emphasized the necessity of thorough testing, risk management, and contingency planning when dealing with third-party vendors and critical IT systems.

These examples illustrate that vendor failures can lead to substantial operational disruptions, financial losses, and reputational damage. Organizations must proactively assess and manage third-party risks to ensure operational resilience and safeguard against potential failures.

Understanding Operational Resilience in the Context of Third-Party Risk

Operational resilience is the ability of an organization to continue delivering critical operations through disruption. This encompasses the capacity to anticipate, withstand, adapt to, and recover from adverse events. In the context of third-party risk, operational resilience involves ensuring that external service providers can maintain their services during disruptions and that the organization can manage and mitigate the impact of any third-party failures.

The Office of the Comptroller of the Currency (OCC) emphasizes that effective operational resilience requires integrating third-party risk management into the organization's overall risk management framework. This includes identifying critical third-party services, assessing the risks associated with these services, and implementing controls to mitigate potential disruptions.

According to Capco, organizations should conduct thorough due diligence when onboarding third-party vendors, including evaluating their business continuity and disaster recovery plans. Regular assessments and audits of third-party providers help ensure that they maintain adequate operational resilience capabilities.

The Xcina Consulting whitepaper highlights that operational resilience is not solely about internal processes but also involves understanding and managing the resilience of third-party suppliers. This holistic approach ensures that organizations are better prepared to handle disruptions originating from external sources.

Regulatory frameworks such as the Digital Operational Resilience Act (DORA) in the European Union mandate that financial entities assess and manage the operational resilience of their Information and Communication Technology (ICT) third-party providers. DORA requires entities to conduct resilience testing and maintain a register of all ICT third-party providers, ensuring transparency and accountability.

International standards like ISO 31000, ISO 22301, and ISO 28000 provide guidelines for risk management, business continuity, and security management systems, respectively.
