An Empirical Study of Bug Bounty Programs
Thomas Walshe, Andrew Simpson
Abstract
The task of identifying vulnerabilities is commonly outsourced to hackers participating in bug bounty programs. As of July 2019, bug bounty platforms such as HackerOne have over 200 publicly listed programs, with programs listed on HackerOne being responsible for the discovery of tens of thousands of vulnerabilities since 2013. We report the results of an empirical analysis that was undertaken using the data available from two bug bounty platforms to understand the costs and benefits of bug bounty programs both to participants and to organisations. We consider the economics of bug bounty programs, investigating the costs and benefits to those running such programs and the hackers that participate in finding vulnerabilities. We find that the average cost of operating a bug bounty program for a year is now less than the cost of hiring two additional software engineers.
