The National Vulnerability Database (NVD) is a comprehensive public resource managed by the National Institute of Standards and Technology (NIST). It catalogs known software and hardware security vulnerabilities, providing detailed information such as severity scores, impact metrics, and references to related advisories. The NVD uses the Common Vulnerabilities and Exposures (CVE) system as its foundation, enabling organizations and individuals to identify, assess, and manage security risks more effectively. By offering timely updates and standardized data, the NVD supports cybersecurity professionals in prioritizing remediation efforts, compliance, and risk management. It is widely used by security teams, developers, and researchers worldwide.
