TPRM vendor classification is the process of categorizing vendors based on their criticality, risk level, and service type. Vendor classification helps to prioritize and allocate resources for vendor assessment, monitoring, and remediation. Vendor classification should be updated periodically to reflect changes in the business environment, vendor performance, and regulatory requirements.

When updating TPRM vendor classification requirements with a focus on availability, the risk rating factors that provide the greatest impact to the analysis are the impact on operations and end users, the impact on revenue, and the impact on regulatory compliance. This is because:

Availability is the degree to which a system or service is accessible and functional when required by authorized users. Availability is a key component of information security and business continuity, as it ensures that the business can operate normally and deliver value to its customers and stakeholders.

Impact on operations and end users measures the extent to which a vendor’s service disruption or failure affects the business processes, functions, and activities that depend on the vendor’s service. A high impact on operations and end users means that the vendor’s service is essential for the business to perform its core functions and meet its objectives, and that any downtime or degradation of the service would cause significant operational delays, inefficiencies, or losses.

Impact on revenue measures the extent to which a vendor’s service disruption or failure affects the business’s income, profitability, and market share. A high impact on revenue means that the vendor’s service is directly or indirectly linked to the business’s revenue generation, and that any downtime or degradation of the service would cause substantial financial losses, reduced customer satisfaction, or competitive disadvantage.

Impact on regulatory compliance measures the extent to which a vendor’s service disruption or failure affects the business’s adherence to the laws, regulations, standards, and contractual obligations that govern its industry, sector, or jurisdiction. A high impact on regulatory compliance means that the vendor’s service is subject to strict regulatory requirements, and that any downtime or degradation of the service would cause serious legal penalties, fines, sanctions, or reputational damage.

Therefore, these three factors are the most important to consider when updating TPRM vendor classification requirements with a focus on availability, as they reflect the potential consequences and risks of vendor unavailability for the business.
