SOC 1 (SSAE 18 / ISAE 3402) D.4: SOC 1 D.4 Other information provided by the service organisation kept consistent with the description and clearly outside the opinion

Where the report document carries other information from the service organisation (marketing material, business continuity narratives, additional controls), it is placed in its own section, identified in the report as not covered by the opinion, and the auditor reads it for material inconsistencies with the description and for misstatements of fact, which management corrects.
