NIST SP 800-37 is the Guide for Applying the Risk Management Framework, a document for guidance, not a repository of vulnerability data.

The National Vulnerability Database (NVD) is a comprehensive cyber security vulnerability database that integrates all publicly available US government vulnerability information, providing a central reference for vulnerability management and compliance with standards like those from NIST.

SCAP (Security Content Automation Protocol) is a suite of specifications that standardize how to enumerate and assess security vulnerabilities and configurations, not a repository itself.

ISCM (Information Security Continuous Monitoring) is a program or process for continuously monitoring security controls and information systems, not a database of vulnerabilities.
