2,650+ unique open source licenses
The KnowledgeBase contains more than 2,650 unique open source licenses (GPL, LGPL, Apache, etc.), with full license text for the most popular open source licenses and dozens of encoded attributes and obligations for each license.
132,000+ unique vulnerabilities
We track more than 132,000 unique vulnerabilities affecting more than 425,000 component versions, including thousands of Black Duck exclusive vulnerabilities not contained in the National Vulnerability Database (NVD) or other sources.
3.9+ million open source projects
We catalog more than 3.9 million unique open source projects, allowing highly accurate matches to the components that compose your software, including modified code and open source code snippets.
Deep License Data
Deep License Data identifies “embedded licenses” to help organizations trust the use of thousands of projects with no declared license. Deep License Data exposes projects with no license data, which are high-risk, and provides full license text for the most popular open source licenses.
With millions of open source projects available globally from thousands of websites and forges, it can be difficult (and sometimes impossible) to effectively track your open source use and manage the application security, software license compliance, and component quality risks that come with it. Black Duck solves this problem, giving development, security, and legal teams maximum visibility and control of open source in their applications and containers. The open source KnowledgeBase is the foundation for Black Duck, providing the industry’s most comprehensive database of open source component, vulnerability, and license information.
