A Qualitative Document Analysis of Public Vulnerability Disclosure and Bug Bounty Policies from Selected Technology Companies
Abstract
Public vulnerability disclosure policies and bug bounty programmes are now common instruments of cybersecurity governance, but the quality of these documents varies in ways that affect researcher participation, organisational accountability, and user protection. This paper re-examines public vulnerability disclosure and bug bounty policies from selected technology companies through qualitative document analysis. The analysis treats policy documents not as routine support pages, but as organisational texts that define authorised conduct, allocate risk, communicate trust, and structure the practical relationship between companies and external security researchers. The study focuses on six dimensions: scope, reporting procedure, safe-harbour protection, reward logic, disclosure timing, and response transparency. The paper finds that public policies commonly perform two roles at once. On the surface, they invite cooperation and signal openness to external security reporting. At a deeper level, they preserve organisational control through eligibility rules, exclusions, conditional legal protection, discretionary reward decisions, and open-ended remediation timelines. This tension is consistent with prior research showing that vulnerability disclosure is shaped not only by technical discovery, but also by incentives, market design, vendor response behaviour, legal uncertainty, and trust between organisations and researchers. The paper argues that policy maturity should therefore be assessed by documentary quality rather than by visibility alone. A mature policy should provide clear scope, credible safe harbour, usable reporting instructions, transparent triage expectations, proportionate disclosure rules, and fair reward criteria. These features do not remove company control, but they make that control more predictable and accountable. The analysis concludes that disclosure and bounty policies are operational governance instruments, and that weak drafting can reduce the practical value of otherwise well-intentioned cybersecurity programmes.
