HackerOne

HackerOne is a security company founded in 2012 that describes itself as the global leader in Continuous Threat Exposure Management (CTEM). It combines agentic AI with a large community of ethical hackers to help organisations discover and remediate security vulnerabilities. The company's technical work spans offensive security, vulnerability management, AI red teaming, code security review, penetration testing and bug bounty operations. It operates globally.

Its products include Bug Bounty Programs, which connect organisations with ethical hackers; Penetration Testing as a Service; Vulnerability Disclosure Management; AI Red Teaming, for adversarial testing of AI systems; Expert Code Security Reviews; and Hai Insight Agent, an AI-powered agent that accelerates vulnerability remediation. Gartner has recognised the company for leadership in AI Security Testing, and some critical vulnerabilities have been resolved in as little as 56 hours through its remediation work.

Since 2012, more than 200,000 vulnerabilities have been discovered and remediated through the platform, and more than $230 million has been paid to security researchers, including $81m in 2024 alone. The network of registered hackers exceeds one million. In 2024 the company recorded a 10% increase in critical and high-severity reports, and remediation times fell from months to days.

Its customers span the U.S. Department of Defense, General Motors, Goldman Sachs and Coinbase, among other technology, financial services, automotive and government organisations. The company has been named a Most Loved Workplace for Young Professionals and maintains a global community of security researchers.
