Klocwork is Perforce Software’s static application security testing and code-analysis product for mission-critical and embedded software teams. It analyzes C, C++, C#, Rust, Java, JavaScript, Python, and Kotlin for security vulnerabilities, defects, quality issues, coding-standard violations, and code smells. Teams can use it across Windows and Linux, with API access for programmatic workflows. The positioning fits engineering organizations that need policy enforcement, developer feedback, and centralized oversight across large or specialized codebases.

Pricing is handled through contact sales, so purchase planning starts with a conversation rather than a published plan comparison. The platform’s scope is broad: command-line tools and quality gates support CI/CD workflows, while incremental and differential analysis focus attention on changed files. Perforce Validate centralizes analysis results, trends, configurations, and reporting. Risk prioritization adds filters, suppressions, baselines, and Smart Rank, giving teams several ways to organize findings instead of treating every result identically. Custom checker creation also supports organization-specific rules.

Klocwork’s ecosystem coverage is a notable strength. IDE plugins are available for Visual Studio, Eclipse, IntelliJ IDEA, CLion, Android Studio, QNX Momentics, Wind River Workbench, and Visual Studio Code, with integrations including GitLab, GitHub Copilot, Microsoft Visual Studio, Eclipse, IntelliJ IDEA, Visual Studio Code, and Perforce Validate. AI-assisted remediation suggestions are available in the developer workflow, and results can be exposed through a REST API or XML, JSON, and PDF formats. Choose Klocwork when embedded or enterprise teams need broad IDE coverage, governance controls, and centralized reporting. Consider another option when publicly documented pricing or an open-source product is a priority.
