How it's worked out

  • Inherent = (criticality + data access + substitutability) ÷ 15 × 100. Residual = inherent × control evidence factor
  • Equal weights; evidence factors are platform-defined
NoteA platform-defined score to make tiering consistent. Set your own weights and review frequency in your third-party risk policy.

Source: Platform-defined; aligned in spirit with ISO/IEC 27001:2022 A.5.19 to A.5.22
