Black Duck Coverity vs Security Code Scan

Black Duck Coverity is a paid static analysis solution for finding security vulnerabilities and code quality defects in source code before software ships. It analyzes code without executing it, scanning across files and libraries in entire codebases. Black Duck lists support for 22 programming languages and more than 250 frameworks, along with standards including MISRA, AUTOSAR, ISO 26262, PCI DSS, CERT C/C++/Java, DISA STIG, OWASP Top 10, and CWE Top 25. Coverity is TÜV SÜD certified for IEC 61508-3 support-tool requirements and qualified for use up to ASIL D under ISO 26262 and Level A under DO-178C. The Code Sight IDE plug-in offers real-time results, issue summaries, and code fixes. IDE, SCM, and CI integrations can trigger scans on commits and pull requests; listed connections include GitHub, GitLab, Bitbucket, Azure DevOps, Jenkins, and others. Deployment can be fully air-gapped on premises, including Kubernetes clusters. Pricing is customized to team size and codebase and supplied by quote.

Security Code Scan is a free, open-source static analyzer for .NET projects written in C# and VB.NET. It detects vulnerability patterns such as SQL injection, cross-site scripting, CSRF, and XML external entity injection, using inter-procedural taint analysis to follow input data. Projects can be analyzed in the background through IntelliSense or during a build. For delivery workflows, it supports GitHub and GitLab pipelines, MSBuild, and a stand-alone runner; custom integrations can emit SARIF results and place warnings alongside other build messages. Users can define taint sources, sinks, sanitizers, validators, and project-specific settings. The analyzer supports Visual Studio 2019 or higher, while the project says other Roslyn analyzer editors such as Rider or OmniSharp should work. Releases are available as a NuGet package, Visual Studio extension, and stand-alone runner for Windows and Linux. The maker warns that the extension or NuGet package can slow the IDE and recommends CI/CD pipelines as the more common use case. Audit mode is off by default. The repository identifies an LGPL-3.0 license.
