What is ISAE 3000?
ISAE 3000 (International Standard on Assurance Engagements 3000) is an international assurance standard used for independent assessments of non-financial information – such as information security, GDPR compliance, and internal controls. The standard is issued by The International Auditing and Assurance Standards Board (IAASB) and is widely applied in organizations where security, transparency, and accountability are key focus areas.
Purpose of ISAE 3000
The purpose of ISAE 3000 is to provide assurance that an organization has adequate internal controls and processes in place. When a company obtains an assurance report, it means that an independent third party has assessed whether security measures and data processes are accurately described, properly implemented, and – where relevant – functioning effectively. The report is particularly relevant for handling personal data and IT operations.
How is the audit conducted?
The audit is performed by an independent auditor who evaluates the organization’s security and control environment based on defined criteria. The auditor analyzes documentation, performs sample testing, and applies professional skepticism throughout the process. The report documents the auditor’s conclusion on whether the described controls meet the requirements of the ISAE 3000 standard.
What does it mean for Addo Sign’s customers?
