Vendor Diligence and Management

Contact Us

Third-party risk management (TPRM) is the process of monitoring, validating, and remediating risks presented by third-party vendors. TPRM helps ensure your vendors protect your data, comply with regulations, and provide sustainable services that meet your requirements. However, vendor risk management can be a costly and time-consuming task. Our vendor management outsourcing service (VMOS) allows your company to offload the vendor due diligence and risk assessment process. Unlike other risk management solutions and vendor management software providers, ACA's VMOS will help your company save valuable time and resources in order to focus on more strategic tasks.
