Privileged Access Risk Score Calculator
Calculates a composite Privileged Access Risk Score (PARS) on a 0–100 scale by weighting account exposure, access breadth, authentication controls, and behavioral activity factors. Higher scores indicate greater risk requiring immediate remediation.
Total Privileged Accounts
Shared / Generic Privileged Accounts
Dormant Accounts (no login > 90 days)
Number of Critical Systems Accessible
Total Critical Systems in Environment
MFA Coverage on Privileged Accounts (%)
PAM Tool Coverage on Privileged Accounts (%)
Off-Hours Privileged Logins (last 30 days)
Total Privileged Logins (last 30 days)
Failed Privileged Login Attempts (last 30 days)

#### Formula
PARS = 0.30 × C1 + 0.25 × C2 + 0.25 × C3 + 0.20 × C4
Where each component is scaled 0–100:
-
C1 — Account Exposure: [(Shared Accounts / Total Accounts) + (Dormant Accounts / Total Accounts)] / 2 × 100
-
C2 — Access Breadth: (Systems Accessible / Total Critical Systems) × 100
-
C3 — Authentication Control Gap: [(1 − MFA Coverage%) + (1 − PAM Coverage%)] / 2 × 100
-
C4 — Behavioral Activity: [(Off-Hours Logins / Total Logins) + min(Failed Logins / Total Logins, 1)] / 2 × 100
Risk Bands: 0–24 Low | 25–49 Moderate | 50–74 High | 75–100 Critical
