The frequency for conducting a vendor reassessment is not necessarily defined by regulatory obligations, but rather by the risk rating and criticality of the vendor, as well as the changes in the vendor's environment, performance, and controls. Regulatory obligations may provide some guidance or minimum requirements for vendor reassessment, but they are not the sole determinant of the reassessment frequency. According to the Shared Assessments Program Tools User Guide, "The frequency of reassessment should be based on the risk rating and criticality of the vendor, as well as any changes in the vendor's environment, performance, or controls. Regulatory guidance may also influence the frequency of reassessment."1 Similarly, the CTPRP Study Guide states, "The frequency of reassessment should be based on the risk rating and criticality of the vendor, as well as any changes in the vendor's environment, performance, or controls. Regulatory guidance may also influence the frequency of reassessment."2 References:
