Black Duck KnowledgeBase

The Black Duck by Synopsys open source KnowledgeBase is the industry’s most comprehensive database of open source project, license, and security information, sourced and curated by the Synopsys Cybersecurity Research Center (CyRC), covering more than 2.7 million open source components from over 14,000 forges and repositories.

Get unparalleled insight into open source components

2,500+ unique open source licenses

The KnowledgeBase contains more than 2,500 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.

117,000 unique vulnerabilities

We track more than 117,000 unique vulnerabilities affecting more than 330,000 component versions, including Black Duck-exclusive vulnerabilities not contained in the National Vulnerability Database (NVD) and other sources.

2.7 million open source projects

We catalog more than 2.7 million 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.
