The bug bounty model brings together security researchers from around the world, including tens of thousands from over 100 countries, to help organizations identify vulnerabilities in their code. These researchers are not all professional hackers, but rather white hat hackers who approach breaking into code like an adversary to help combat cyber attacks. Many of these researchers work full time in security and use bug bounty programs as a way to stay up-to-date on their skills or earn extra income. The motivations of bug hunters vary widely, with many reinvesting earnings back into their craft and others seeking to expand their knowledge and build their skill set through the challenge of the hunt. Bugcrowd's crowd is vetted through an identity verification process, which may be useful for organizations that require specific skill-sets or compliance reasons.
