Independent SOC assessments have become an important part of building trust between service providers and their clients. SOC 1 engagements are performed in accordance with Statement on Standards for Attestation Engagements (SSAE) 18, Reporting on Controls at a Service Organization. SOC 1 reports focus solely on controls at a service organization that are likely to be relevant to an audit of a user entity’s financial statements. SOC 2 and SOC 3 engagements address controls at the service organization that relate to operations and compliance.
