Feature Comparison

The following table compares Black Duck SCA and Mend across key aspects relevant to open-source security, based on industry analysis as of January 2023:

Aspect	Black Duck	Mend
Developer Guidance	Score: 2/5. Directs to current versions; developers must research risks and compatibility.	Score: 3/5. Provides patch risk details; developers still assess compatibility.
SBOM Support	Score: 4/5. Imports/exports multiple SBOM formats, strong in C/C++ analysis.	Score: 2/5. Exports one SBOM format, no import, limited nesting visibility.
Accuracy (False Positives)	Score: 2/5. False positive rate: 5–10%.	Score: 3/5. False positive rate: 2–5%.
DevOps Integration	Score: 4/5. Supports build pipelines, container/binary scanning; no runtime protection.	Score: 3/5. Integrates with build environments; no binary scanning or runtime protection.
Total Cost of Ownership	Score: 2/5. High pricing, increased labor costs due to guidance and accuracy issues.	Score: 3/5. Straightforward pricing, but labor costs from false positives.

1. Developer Guidance

• Black Duck: Offers limited guidance, directing developers to current versions but requiring additional research on risks and compatibility. This can slow down remediation efforts for teams addressing open-source vulnerabilities.
• Mend: Provides better guidance by detailing patch risks, helping developers prioritize remediation. However, compatibility assessments still require manual effort, which may impact efficiency.

2. SBOM Support

• Black Duck: Excels in SBOM support, scoring 4/5. It supports multiple SBOM formats for import and export, offering clear visibility into dependency relationships, particularly for C and C++ code, which is critical for identifying vulnerabilities in enterprise applications.
• Mend: Scores 2/5 due to limited SBOM capabilities. It exports SBOMs in one format but lacks import functionality and robust nesting visibility, which may hinder complex dependency management.

3. Accuracy (False Positives)

• Black Duck: With a 5–10% false positive rate, Black Duck requires more manual effort to filter out non-issues, potentially increasing remediation time for open-source vulnerabilities.
• Mend: Performs better with a 2–5% false positive rate, allowing developers to focus on genuine vulnerabilities, enhancing efficiency in securing open-source components.

4. DevOps Integration

• Black Duck: Scores 4/5 for strong integration with build pipelines, repositories, and support for container and binary scanning, which are crucial for securing open-source components across the development lifecycle.
• Mend: Scores 3/5, offering solid integration with build environments and repositories but lacking binary scanning capabilities, which may limit its effectiveness in certain open-source security scenarios.

5. Total Cost of Ownership

• Black Duck: Scores 2/5 due to high pricing ($10,000–$70,000) and increased labor costs from limited guidance and higher false positives, which can impact the cost-effectiveness of open-source security management.
• Mend: Scores 3/5 with straightforward pricing based on contributing developers, but labor costs persist due to false positives and limited guidance.
