Formula Used
This calculator separates data leakage risk into likelihood, impact, and control effectiveness. Most 1-5 ratings are converted into a 20-100 scale.

Frequently Asked Questions
1. What does this calculator measure?
It estimates residual data leakage risk by combining exposure likelihood, business impact, and defensive control strength into one structured score.
2. Why are some inputs percentages and others 1-5 ratings?
Ratings work well for qualitative judgments, while percentages better represent technical coverage such as encryption or DLP deployment across an environment.
3. How should I rate data sensitivity?
Use 1 for public or low-value information and 5 for highly sensitive records like personal, financial, health, legal, or privileged data.
4. What is detection lag?
Detection lag is the time between a leakage event and when your team identifies it. Longer delays increase risk because harmful exposure lasts longer.
5. Does a high control score guarantee low risk?
No. Strong controls help, but very sensitive data, broad exposure, poor behavior, or major legal consequences can still produce elevated residual risk.
6. Can I use this for vendor assessments?
Yes. Rate third-party sharing, detection lag, encryption, DLP maturity, and response readiness using the vendor’s evidence and contract commitments.
7. How often should I reassess leakage risk?
Reassess after major system changes, new data flows, vendor onboarding, incidents, policy updates, or at least once per quarter.
8. Is this a replacement for formal risk governance?
No. It is a practical scoring aid that supports formal governance, audits, and control reviews, not a substitute for them.
