Trust Services

    Trust Services 

    Trust Services are defined as a set of professional assurance and advisory services based on a common framework (that is, a core set of principles and criteria) to address the risks and opportunities of IT. Trust Services principles and criteria are issued by the Assurance Services Executive Committee of the AICPA.

    The Trust Services Principles and Criteria provide guidance when offering assurance services, advisory services, or both on information technology (IT)-enabled systems including electronic commerce (ecommerce) systems. It is particularly relevant when providing services with respect to security, availability, processing integrity, privacy, and confidentiality.

    Two specific assurance service offerings developed by the AICPA and CPA Canada, SysTrust and WebTrust, are based on the Trust Services Principles and Criteria. Practitioners now must be licensed by the CPA Canada to use these registered service marks.
