Map threats, causes, preventive barriers, consequences, and recovery measures in a clear bowtie structure. The standard method for structured risk analysis.

Everything you need to build professional bowtie risk diagrams.
Organize hazards, threats, causes, preventive controls, consequences, and mitigating controls in the classic bowtie layout.
Build diagrams interactively with customizable shapes, colors, and connectors. Export-ready visuals.
Create separate bowtie diagrams for different risks, projects, or departments.
Build a complete risk picture in three steps.
Start with the central hazard event — the risk you want to analyze. This becomes the center of your bowtie.
Add threats and causes on the left, consequences on the right. Build the full picture of what could go wrong and what the impact would be.
Place preventive barriers between causes and the hazard, and mitigating controls between the hazard and consequences.
Professional risk analysis without the complexity.
Label each section of the bowtie with custom category names for your industry or framework.
Assign colors to different categories for instant visual distinction between causes, barriers, and consequences.
Add detailed notes to any element to capture rationale, evidence, or action items.
Adjust box sizes, colors, fonts, and connector styles to match your organization's standards.
Link items across categories to show relationships between causes, barriers, and consequences.
Manage several bowtie diagrams — one per risk scenario, project, or assessment.
