HackerOne Code is a code security solution that combines AI with human expertise to help developers build secure software and catch vulnerabilities before they reach production. Their AI-powered technology, Hai, identifies high-risk code changes that require expert validation, automating initial reviews and filtering out low-risk issues to scale security resources. Expert human reviewers then validate findings, virtually eliminating false positives and providing precise, actionable insights. The service integrates with major SCM platforms and supports all programming languages and frameworks, offering remediation guidance within developers' existing tools. This approach aims to improve code quality, reduce technical debt, and enhance security awareness within development teams.
