The most concerning issue when reviewing the results of an independent control assessment to determine the effectiveness of a vendor's control environment is that the controls had recurring noncompliance. This indicates that the vendor's controls are not operating as intended or designed, and that the vendor is not taking corrective actions to address the control deficiencies. This can increase the risk exposure and liability for the organization that outsources the service or function to the vendor. The report being provideddirectly from the vendor, the risk associated with multiple control gaps being accepted, and the control owners disagreeing with the auditor's recommendations are other possible issues, but they are not as critical as the recurring noncompliance.
