A SOC 1 report documents a cloud service provider’s internal controls that may be relevant to a customer’s financial reporting. This report is particularly useful for organizations that audit financial statements.
SSAE 18 / ISAE 3402 Type II
The Auditing Standards Board of the American Institute of Certified Public Accountants (AICPA) created the Statement on Standards for Attestation Engagements No. 18 (SSAE 18) to keep pace with globally recognized international accounting standards.
SSAE 18 aligns closely with the International Standard on Assurance Engagements 3402 (ISAE 3402).
SSAE 18 and ISAE 3402 are used to generate a report by an objective third party attesting to a set of assertions made by an organization about its controls. The Service Organization Controls (SOC) framework is the method by which the control of financial information is measured.
Google Cloud Platform undergoes a regular third-party audit to certify individual products against this standard.
