Assess · Risk Assessment

Available

A risk score you can explain to your board — and your auditor.

FlashTower's Risk Engine evaluates your answers against a versioned library of deterministic rules. Each rule has a permanent ID, a severity, a weight, a plain-language condition, an explanation, remediation steps, evidence requirements, and framework mappings. The same answers always produce the same result.

Details

Why deterministic

Security decisions need to be reproducible. Large language models are useful for explaining findings, but they should not decide your score. FlashTower never lets an AI model determine findings or scores; AI is used only, and optionally, to write narrative around deterministic results.

How findings are weighted

Each severity has a base point value, multiplied by the rule's weight. When the same rule applies to several AI systems, each additional occurrence counts for half the previous one, so one systemic issue does not overwhelm the score.

Versioned and auditable

Every assessment records the ruleset version and scoring version it was evaluated with. When rules change, their version number changes too, so past reports remain reproducible.

Methodology

How the score is calculated.

Scoring version 1.0.0, ruleset 2026.09.1. Higher scores mean more risk.

1. Points per finding

Each finding contributes its severity's base points multiplied by the rule's weight (0.5–1.5).

SeverityBase points
Critical25
High12
Medium5
Low2
Info0

2. Repeat decay

When one rule applies to several AI systems, the n-th occurrence counts 0.5n−1 of full value. A single systemic issue is visible without overwhelming the score.

3. Saturating score

score = round(100 × (1 − e^(−points / 60)))

The curve keeps the score between 0 and 100. If any Critical finding exists, the score is raised to at least 60.

4. Rating bands

  • Low 0–19
  • Moderate 20–39
  • Elevated 40–59
  • High 60–79
  • Critical 80–100

The ruleset

Every rule currently in the FlashTower Risk Engine. Rule IDs are permanent; changes increment the rule's version.
