Choose Your Static Analysis Use Case

Continuous Compliance  

Compliance becomes difficult when teams manage evidence, deviations, and standards adherence manually. For safety-critical software, it’s almost impossible without tools qualified by an independent authority. Static analysis tools help organizations maintain compliance continuously throughout development rather than treating compliance testing as a release-time event. 

LDRA tool suite

Best suited for organizations seeking strong traceability between requirements and tests and certification-oriented workflows run at key points in the software lifecycle.

Perforce QAC

Best suited for teams building safety-certified and security-critical software that requires continuous compliance testing, deep code analysis, and CI/CD integration throughout the software lifecycle.

Perforce Klocwork

Best suited for enterprise organizations managing continuous compliance across multiple teams, products, and software variants. Klocwork's advantages include analysis speed, scalability, language coverage, CI/CD integration, compiler support, IDE integration, and AI-assisted remediation.

Enterprise Static Application Security Testing (SAST) 

As software systems grow larger and more interconnected, identifying vulnerabilities early reduces risk, improves code quality, and lowers remediation costs. Effective SAST solutions should provide scalable analysis and accurate results to improve developer workflow efficiency. 

LDRA tool suite

Best suited for organizations that need broader security standards support and traceability from requirements through tests and certification evidence. It also supports test methods beyond static analysis, including dynamic analysis and code coverage.

Perforce QAC

Best suited for safety-critical software development where it’s advantageous to consolidate SAST and functional safety checks driven by deep static analysis. QAC’s strengths include ease of use, fast analysis, accuracy, and strong CI/CD integration.

Perforce Klocwork

Best suited for enterprise-scale SAST that covers large, complex codebases (including millions of lines of code across multiple languages), multiple product variants, and long-lived software systems.

Functional Safety Standards Compliance  

Static analysis tools help automate standards enforcement, improve traceability, and reduce the effort required to prepare for audits and certification reviews. 

LDRA tool suite

Broad support for functional safety standards and lifecycle traceability from requirements to certification evidence.

Perforce QAC

Purpose-built for organizations where safety and compliance are core business requirements, requiring deeper analysis and centralized compliance governance (through Perforce Validate).

Perforce Klocwork

Supports functional safety compliance across multiple products and engineering teams, with support for a broader range of languages, compilers, IDEs, and CI/CD tools.

MISRA Compliance  

MISRA guidelines are foundational for many safety-critical software programs. Automated enforcement through static analysis tools helps organizations reduce manual review effort, identify violations earlier, and generate evidence for certification activities.  

LDRA tool suite

Supports major MISRA editions through the optional TBmisra module and offers MISRA training courses.

Perforce QAC

Best fit for safety-critical software development, with comprehensive MISRA coverage across C, C++, and Rust environments built in.

Perforce Klocwork

Built-in coverage for MISRA programs requiring governance, reporting, and operational scalability across large projects, combined with SAST capabilities.

Shift to AI-Enabled Development 

AI is changing how software is developed, but organizations still need confidence that generated or modified code meets quality, security, and compliance requirements. Teams are adopting static analysis tools to validate code produced in AI-assisted workflows and runtime software that includes AI components. 

LDRA tool suite

Best suited for organizations focused on verification and validation of AI-generated code and AI components within regulated environments. 

Perforce QAC

Best suited for organizations seeking AI-assisted remediation and MCP capabilities to accelerate development while maintaining compliance and complete oversight of AI-generated code and AI components.

Perforce Klocwork

Best suited for enterprises integrating AI into large, complex development environments, including AI-assisted remediation and MCP Server support.
