What Is ISAE 3402 Training?
ISAE 3402 training is specialist professional development in IAASB International Standard on Assurance Engagements 3402 — the international standard for assurance reports on service organisation controls over financial reporting. It covers Type I and Type II reporting, control objectives, audit evidence, and ISAE 3402 engagement readiness. ISAE 3402 is the international equivalent of SOC 1 (SSAE 18).
ISAE 3402 is the international assurance standard that service organisations use to demonstrate the effectiveness of their internal controls to their clients' auditors. For outsourcing providers, financial services platforms, cloud infrastructure companies, and any service organisation whose controls affect a client's financial reporting, ISAE 3402 is a business requirement.
This CPD-certified practitioner course gives UK auditors, service organisation management, and compliance professionals the technical knowledge to design, document, test, and report on ISAE 3402-compliant controls — whether preparing for an engagement, managing an existing programme, or advising client service organisations.
