Unqualified opinion
Also known as: Clean opinion, Unmodified opinion
An unqualified opinion is the highest level of assurance an auditor can provide. It states that the subject matter—such as financial statements or internal controls—is presented fairly and complies with the required standards in all material respects. This means the auditor found no significant issues that would require a modification to the report.
In practice
A practitioner encounters this in the final audit report, where it serves as official confirmation that an organization's security controls are operating effectively. For example, receiving an unqualified opinion on a SOC 2 report allows a company to prove its compliance posture to customers and partners.
