Threat Modeling Calculators

Interactive tools to help you score risks, choose the right methodology, and visualize your threat landscape.

DREAD Risk Scorer

Score each threat across five dimensions to calculate a prioritized risk level. Add multiple threats to compare and rank them.

Quantitative
Damage Potential How severe is the damage if exploited?
5
Reproducibility How easily can the attack be reproduced?
5
Exploitability How much skill/resources does exploitation require?
5
Affected Users How many users are impacted if exploited?
5
Discoverability How easy is it for an attacker to find the vulnerability?
5
Score 5.0
Medium

Scoring Reference

1–3 Low risk Monitor, low priority
4–5 Medium risk Plan mitigation
6–7 High risk Prioritize fix
8–9 Critical risk Immediate action
10 Severe Stop-ship issue
Formula (D+R+E+A+D) ÷ 5
