Bugcrowd offers various program types for researchers to participate in, including Bug Bounty Programs, which allow researchers to choose when and how they want to test, and can earn rewards for discovering vulnerabilities. There are two types of Bug Bounty Programs: private, invitation-only programs that match researchers with specific skill sets, and public programs that are publicly available on the website. Researchers can also participate in Vulnerability Disclosure Programs (VDPs), which provide a means for reporting security issues on company assets, and Next Generation Pen Test (NGPT) engagements, which combine bug bounties with compliance-driven outcomes of pen tests. These programs cater to different needs and skill sets, and Bugcrowd aims to equip researchers with the necessary tools and support to succeed in each program type.
