Enterprise Authority to Operate (EATO)
Enterprise Authority to Operate (EATO) targets risks inherent in Anything as a Service (XaaS) products, underlying cloud based infrastructure or platforms, information security and privacy, and the topics of Business Continuity, Data Retention, Archiving, and vendor/service provider controls and risks.

The EATO Working Group defines and sets auditing requirements and minimum standards required to be achieved to pass the EATO assessment and certification. The EATO Working Group defines requirements towards consultancy companies to support small and mid-sized vendors/service providers, with the aim of enabling them to derive architectures and designs compliant with the EATO certification schemes.

What do we discuss?

The objective of the program will be to harmonize with existing third-party certifications and audit standards to avoid duplication of effort and cost.
The EATO Working Group will define the control and assessment framework, assessment guidance and auditing principles and requirements.

The EATO is based on the technical best practices and control frameworks defined within relevant CSA’s Working Groups, such as for instance the Cloud Control Matrix (CCM), the Consensus Assessment Initiative Questionnaire (CAIQ), the Level Agreement research initiatives, as well as the IoT Control Framework.
