DSPs provide annual assurance that their products and services remain compliant with the OSF controls and requirements, responding to the annual review ticket raised in the DSP service desk; the review checks the currency of the self-assessment (current for two years from ATO approval) or independent certification (current to the certificate's expiry). The ATO also conducts ad hoc reviews.
