HackerOne

HackerOne is a cybersecurity company that operates a platform for bug bounty and responsible vulnerability disclosure. The service connects organizations with a global community of security researchers who identify, report, and help remediate security weaknesses in software, networks, and services. Organizations can run public, private, or invite-only bug bounty programs, define scope and reward levels, and manage submissions through a workflow that covers triage, validation, remediation, and payout. The platform also includes features for vulnerability disclosure policies, program analytics, risk scoring, and integration with issue trackers and security tooling.

Founded in 2012, HackerOne is headquartered in San Francisco, California, with a worldwide network of researchers and customers. The company positions itself as a marketplace for vulnerability coordination, offering advisory services and professional services to guide program design, disclosure processes, and security testing. It serves customers across multiple sectors, including technology, finance, government, and healthcare, and has been adopted by both private sector companies and public institutions to improve security hygiene.
