Today’s business environment is increasingly globalized and supplier-reliant. As a result, third parties are becoming an increasingly important source of breaches of regulated data. Tightened regulations mean that organizations are susceptible to be liable for the security controls and actions of their third parties.

Third parties play an increasingly important role in the day to day operations of most organizations. The increased demand and reliance on third parties has led to a drastic increase in risk posed to you, the client.

Third party assurance requires a unique, risk-driven approach in order to be effective. Your relationships with your third parties will differ, vendor to vendor, each requiring a unique and custom approach to assessing and managing risk.

SubRosa’s third party assurance program helps its clients to effectively manage third party risk, and enhance reporting and metrics organization-wide and consists of the following key service types:
