VulnHunter employs agentic AI, meaning it operates with a degree of autonomy to analyze vast amounts of code and pinpoint security flaws. Unlike traditional vulnerability scanners that might rely on predefined rules, VulnHunter is designed to emulate the thought processes and methodologies of a human hacker. This allows it to uncover more subtle and complex vulnerabilities that might otherwise go unnoticed, significantly enhancing an organization's defense capabilities against cyber threats.
