Attestation & Assurance Reports

The International Standard on Assurance Engagements (ISAE) 3402 is a globally recognised standard focused on providing assurance over internal controls of service providers that may have a potential impact on their clients' financial figures and/or financial reporting. Service providers use this report to demonstrate the effectiveness of their internal controls to clients, client auditors and other stakeholders.

The International Standard on Assurance Engagements (ISAE) 3000 is a general standard for assurance engagements that does not focus on historical financial information. It includes guidelines for conducting assurance engagements on a variety of topics, such as internal control, compliance and other non-financial information. The form of these reports is largely fixed but it is up to the organisation to determine which framework(s) and/or specific processes within the business or technological environment will be reported on.
  • During a SOC2 assessment, your service provider's compliance is checked against the Trust Services Criteria framework. This structure is very similar to the well-known ISO 27002 and COSO frameworks. 
  • A SOC2 report is intended for your customers and stakeholders, such as auditors or your customers' security officers.
