Third-Party Risk Management for Financial Institutions
Third-party risk assessment is a structured process that companies use to evaluate potential risks introduced by external vendors, suppliers, or contractors to their organisation.
This assessment protects your business from data breaches, regulatory penalties, operational disruptions, and reputational damage. It also strengthens supply chain resilience, safeguards sensitive information, and supports overall business continuity.
This step-by-step guide outlines how to conduct a third-party risk assessment with practical steps, real-world examples, and proven tools that help your team stay compliant, secure, and in control.
All third-party risk assessments start with first defining what the assessment needs to achieve.
Consider which third parties to include, such as vendors with system access, suppliers involved in core operations, or contractors managing regulated data. Identify the risk types you need to evaluate, including cybersecurity, compliance, financial, operational, and legal exposures.
Involve departments such as IT, legal, compliance, finance, and procurement to ensure comprehensive input. Your scope should reflect business objectives and regulatory mandates. For instance, companies under GDPR or DORA must evaluate vendor access to personal data and the resilience of their systems.
Build a centralised inventory of all third-party relationships. Each record should include vendor details, the services provided, and any access to sensitive data or infrastructure.
A complete, searchable inventory of this nature provides full visibility and helps uncover shadow vendors or outdated contracts.
Once inventoried, prioritise third-party suppliers according to their level of access and criticality to business functions. A payroll processor, for example, should rank higher than a non-critical office supply vendor.
Break down vendor risks into different categories that align with what your organisation is likely to encounter.
Importantly, we must also remember that different industries have specific risk focuses. For instance, healthcare organisations must address HIPAA, while fintech firms focus on FCA or PSD2 alignment.
Evaluate each vendor's risk profile using structured tools and documentation. Distribute security questionnaires that reveal data protection practices. Request certifications like SOC 2 or ISO 27001, along with documented policies.
Review past incidents, breach history, or service disruptions. Consider geopolitical concerns if a vendor operates in a region with legal or economic instability. Standardising the assessment process ensures consistency across departments and enables meaningful comparisons between vendors. Prioritise thorough analysis over volume.
Remember, a single well-evaluated critical vendor provides more control than dozens of unchecked low-risk ones.
Adopt a scoring model that measures each vendor based on likelihood and impact. Likelihood estimates the probability that a risk will occur, while impact measures the potential damage. Assign numerical values to each and calculate a composite score.
Vendors with high scores should receive immediate attention. A clear risk matrix visualises the results and simplifies reporting to stakeholders. Prioritisation ensures that limited resources target the vendors that pose the greatest threat to operations and compliance.
Risk management is more effective when approached as a collaborative process. As such, develop a mitigation plan for each vendor identified as high risk.
Possible actions include adding contract clauses around data handling or breach notification, implementing additional security controls, restricting access to sensitive systems, or exploring alternate vendors as backup options.
Engage in open discussions with third parties to communicate expectations and timelines, and always record agreements in service level agreements or appendices to ensure accountability.
Consistency in reporting enables better tracking, benchmarking, and process optimisation over time.
With this in mind, maintain clear records of each step in the assessment process. Documentation supports audits, compliance reporting, and internal reviews.
It also facilitates knowledge transfer between teams and improves long-term consistency. Use structured templates and centralised tools to make documentation scalable across vendors.
Continuous monitoring ensures that changes in risk do not go undetected, because risk assessment is not a one-time task; it's a never-ending exercise.
Establish an ongoing monitoring programme that includes real-time alerts, periodic reassessments, and updates to vendor profiles. Vendors may expand their access, change ownership, or experience security events that affect their risk level. Schedule reviews based on vendor criticality. For instance, high-risk partners may require quarterly assessments, while others may follow an annual cycle.
Standardising your process improves both efficiency and accuracy. Use structured templates for all assessments and apply uniform risk criteria across departments. Classify vendors by service criticality to prioritise your attention.
Build disaster recovery, termination, and data exit strategies into contracts to safeguard your operations. Reassess vendors after major changes such as mergers, new regulations, or service expansions. These practices reduce blind spots and reinforce your organisation's resilience.
Technology accelerates and simplifies risk assessment. Governance, Risk, and Compliance (GRC) platforms and vendor risk management tools enable centralised data storage, automated questionnaires, and real-time dashboards.
These systems can integrate with procurement platforms or contract management tools to improve oversight. Enterprise browsers that isolate vendor access further limit exposure. Automation reduces manual effort, enhances accuracy, and makes the process scalable as your vendor ecosystem grows.
Your third-party risk assessments should feed directly into your broader enterprise risk management strategy. Integration ensures that leadership maintains visibility and that teams across departments work toward shared objectives.
Engage IT, legal, procurement, and compliance early in the process to ensure that third-party risks are captured during onboarding, vendor negotiations, and contract renewals. For a deeper perspective, explore our article Is TPRM Ready for What's Next?
A risk matrix is a simple tool for visualising vendor risk by plotting likelihood on one axis and impact on the other.
This helps your team prioritise efforts and communicate clearly with leadership. To access a downloadable sample or start your assessments with an editable version, find our Risk Rating Matrix.
A third-party risk assessment evaluates the risks posed by vendors, suppliers, or service providers. It examines how these partners might affect your business through data access, operational disruption, or regulatory exposure.
Planning defines your framework and risk policies. Onboarding captures documentation and initiates initial checks. Risk assessment evaluates vendor posture. Ongoing monitoring tracks changes in risk over time. Offboarding ensures access removal and process closure.
A cloud storage provider failing to secure data may expose your customers' information. This can lead to a data breach, regulatory fines, and reputational loss. Third-party risks often result from poor data handling, lack of transparency, or weak cybersecurity practices.
Identify hazards associated with each vendor. Assess those risks based on probability and impact. Evaluate and implement control measures. Record all findings in a centralised system. Review assessments regularly in response to new events or changes in access levels.
