Perforce Klocwork is an enterprise grade SAST solution for C, C++, C#, Rust, Java, JavaScript, Python, and Kotlin. It helps development teams detect security vulnerabilities, quality issues, and reliability defects early, while supporting compliance with industry and regulatory standards.
Klocwork is purpose built to analyze very large, complex codebases and scales to hundreds of millions of lines of code, well beyond the practical limits of many traditional SAST tools. This makes it especially suited for organizations developing long lived, safety critical, or security critical systems.
Designed for DevOps and DevSecOps, Klocwork integrates with complex build systems, CI/CD pipelines, cloud and containerized environments, and common developer tools—enabling consistent security and quality enforcement without slowing development.
Static Application Security Testing (SAST)
Klocwork identifies a wide range of security vulnerabilities, including SQL injection, tainted data flows, buffer overflows, and other insecure coding practices. It also detects bugs and quality issues such as null pointer dereferences, memory and resource leaks, uncaught exceptions, and code smells.
The solution supports compliance with internationally recognized standards including CWE, OWASP, CERT, PCI DSS, DISA STIG, and ISO/IEC TS 17961. Automated CI/CD integrations make continuous security testing practical even for very large systems.
AI Assisted Code Remediation with MCP
Klocwork extends static analysis with AI assisted code remediation, designed to help developers resolve findings faster and with greater confidence. Using MCP based capabilities, Klocwork securely exposes rich static analysis context—defect data, rule knowledge, and precise fix guidance—to supported AI code assist tools directly within the IDE.
Rather than relying on generic AI suggestions, Klocwork’s remediation feature combines deep static analysis insights with comprehensive documentation and exact fix instructions, enabling AI assistants to propose accurate, context aware corrections for security vulnerabilities, quality defects, and coding standard violations. Fixes are presented as clear diffs and require developer review and approval, making the approach suitable for safety and security critical environments.
By integrating remediation into the developer workflow, Klocwork reduces time spent interpreting analysis results, researching fixes, and switching between tools. Developers stay in their IDE, receive guided remediation aligned with secure coding standards and project specific rules, and can immediately re analyze code to validate fixes. This completes the optimal shift left approach—helping teams not only find issues early, but fix them efficiently and consistently.
Project Streams and Enterprise Scalability
Klocwork’s Project Streams feature simplifies managing shared codebases with multiple variants or branches. A single rule configuration can be applied across streams, issues common to multiple variants stay synchronized, and stream specific findings are clearly identified for reporting and compliance.
Developer Focused and Centralized
Klocwork integrates directly into popular IDEs to deliver fast, contextual feedback as developers write code. Out of the box compiler support eliminates manual setup, while centralized dashboards provide visibility into trends, risk, and compliance across projects of any size.
