Audit reports / evidence pack

Why important?

Without evidence, reviews fail (regulator, internal audit).

How measured?

• 0 = No reports/evidence packs available
• 1 = Marketing/statements only, no verifiable material
• 2 = Some artifacts, but incomplete/scope unclear
• 3 = Evidence pack available (often via portal/NDA), scope partly clear
• 4 = Comprehensive artifacts (SOC/C5/ISO/reports) with good freshness, few gaps
• 5 = Comprehensive + current + scope transparent + easily accessible (public/trust center) evidenced
• N/A = no reliable evidence
