HackerOne

HackerOne is the world's leading bug bounty and vulnerability disclosure platform, connecting organizations with a global community of ethical hackers to find and fix security vulnerabilities before attackers can exploit them. Its managed bug bounty programs, pentesting-as-a-service, and vulnerability disclosure policy (VDP) tools help organizations build proactive security programs that complement traditional scanning tools. HackerOne's platform provides structured triage, severity scoring, and remediation tracking that generates audit evidence aligned with SOC 2, PCI DSS, and ISO 27001 requirements. Trusted by the U.S. Department of Defense, Google, Microsoft, and thousands of other organizations, HackerOne has paid out over $300M in bounties to date.
