Discovered vulnerabilities receive severity ratings guiding remediation prioritization. Critical findings enable immediate severe impact requiring urgent fixes. High severity issues pose significant risks warranting prompt attention. Medium and low severity findings guide continuous improvement without demanding emergency responses.

Bug Bounty Program

Financial incentives encourage global security researchers to privately report vulnerabilities.

Bug bounty programs harness worldwide security research talent through structured reward systems for responsible vulnerability disclosure.

Reward Structure

Compensation scales with vulnerability severity encouraging high-value research.

Severity-based rewards:

Critical vulnerabilities enabling direct fund theft, complete system compromise, or widespread user impact receive highest rewards ranging $10,000-$50,000. High severity issues like data breaches, authentication bypasses, or significant denial of service receive $5,000-$15,000. Medium severity findings earn $1,000-$5,000 while low severity issues receive $250-$1,000.

Actual rewards vary based on specific circumstances including vulnerability novelty, exploitation difficulty, and potential impact. Reward decisions balance encouraging valuable research against fiscal sustainability. According to HackerOne Bug Bounty Statistics, well-structured programs attract high-quality researchers discovering serious vulnerabilities.

Bonus considerations:

Particularly elegant vulnerability discoveries or comprehensive security analysis receive bonus compensation beyond base severity ratings. Quality of written reports, proof-of-concept demonstrations, and suggested remediation approaches influence final rewards.

First discovery bonuses reward researchers finding vulnerabilities before others. Duplicate submissions receive reduced compensation reflecting diminished value. This approach incentivizes rapid private disclosure rather than sitting on discoveries waiting for optimal timing.

Responsible Disclosure Process

Structured processes guide researchers from discovery through remediation.

Submission procedures:

Researchers submit findings through official bug bounty platforms or dedicated security email addresses. Submissions require vulnerability descriptions, reproduction steps, potential impact assessment, and ideally proof-of-concept demonstrations.

Initial triage assesses submission validity, severity, and duplication status. Valid unique findings proceed to engineering teams for verification and remediation planning. Invalid or duplicate submissions receive explanations helping researchers understand program scope.
