Choose Your Static Analysis Use Case

Enterprise Static Application Security Testing (SAST) 

Security vulnerabilities are becoming increasingly difficult to identify as software systems grow more complex and development teams move faster. Static application security testing helps organizations detect vulnerabilities early, reduce remediation costs, and improve software security before defects reach production. 

Polyspace

Best suited for development teams working heavily with MATLAB/Simulink-generated code or seeking formal methods-based analysis and verification of software “correctness” in terms of the absence of security defects.

Perforce QAC

Best suited for safety-critical software organizations where provable security and safety compliance requirements intersect with static analysis testing.

Perforce Klocwork

Best suited for organizations that need enterprise-scale SAST across large, complex, and long-lived software systems.

Functional Safety Standards Compliance  

Organizations developing regulated software must demonstrate compliance with safety standards before certifying and releasing products. Static analysis tools automate standards enforcement, generate compliance evidence, and reduce audit and assessment preparation effort. 

Polyspace

Purpose-built for organizations emphasizing formal verification and certification-oriented workflows.

Perforce QAC

Best suited for organizations that require deep, accurate standards coverage to meet strict functional safety guidelines and rules.

Perforce Klocwork

A strong option when standards compliance must scale across large projects and organizations.

MISRA Compliance  

MISRA guidelines are the cornerstone of software safety and security in automotive, aerospace and defense, medical, and other regulated industries. Automated MISRA enforcement helps organizations reduce manual review effort, detect violations earlier, and maintain evidence for certification and audit activities.  

Polyspace

Best suited for teams that need MISRA compliance alongside the broader portfolio of MathWorks products.

Perforce QAC

Best fit for regulated industries such as automotive, aerospace, defense, industrial automation, and medical device organizations where comprehensive MISRA compliance directly impacts product certification and release.

Perforce Klocwork

Built for MISRA compliance programs requiring governance, reporting, and operational scalability, combined with SAST capabilities.

Continuous Compliance  

Many organizations still treat compliance as a periodic activity, increasing the impact and cost of defect remediation. Continuous compliance helps teams resolve issues and maintain standards adherence throughout development, improving development efficiency. 

Polyspace

Best fit for organizations requiring strong formal methods-based verification workflows and standards reporting.

Perforce QAC

Best fit for engineering and compliance teams requiring a single source of truth (through Perforce Validate) backed by deeper standards coverage and CI/CD integration. 

Perforce Klocwork

Best fit when integrating static analysis into compliance programs with large codebases that span multiple products and variants. 

Early Defect Detection

The earlier defects are identified, the less costly they are to resolve. Early defect detection helps engineering organizations reduce rework, improve release predictability, and lower quality, safety, and security risks throughout the software lifecycle. 

Polyspace

Best suited for organizations focused on proving the absence of specific runtime defects through formal analysis as early as possible.

Perforce QAC

Best for teams where broad functional safety standards coverage and AI-assisted code remediation work together to resolve critical issues as early as possible.

Perforce Klocwork

Best suited for mitigating security, safety, and quality issues across large software systems through IDE integration, fast developer feedback, and AI-assisted code remediation.

Why Leading Enterprises Choose Perforce Static Analysis

AI-Assisted Code Remediation icon

AI-Assisted Code Remediation

Perforce QAC and Perforce Klocwork provide AI-assisted remediation capabilities that leverage static analysis context to help developers investigate and choose fixes to resolve defects more efficiently. By keeping engineers in control of code changes, organizations can accelerate remediation while maintaining governance and compliance requirements. 

Delivered via the Perforce Static Analysis MCP server, any MCP-compatible host can connect and apply remediations using its own configured LLM. Support for private, air-gapped environments means no data leaves your network. 

MISRA Compliance Support icon

MISRA Compliance Support

Perforce QAC and Perforce Klocwork deliver extensive MISRA coverage and deep language expertise for C, C++, and Rust. Combined with governance and reporting capabilities through Perforce Validate, organizations can manage MISRA compliance programs at scale while maintaining traceability and audit readiness.

Security and SAST Are Priorities icon

Security and SAST Are Priorities

Organizations need tools that help development teams identify vulnerabilities early and prioritize remediation effectively. Perforce Klocwork combines deep security analysis with SmartRank prioritization, differential analysis, and support for a broad range of security coding standards. This helps teams focus on the most critical issues while integrating security into existing development workflows. 

Better Built to Scale With Depth and Complexity icon

Better Built to Scale With Depth and Complexity

Large software systems present challenges that go far beyond finding defects. Perforce Klocwork was designed for the realities of multiple product variants, distributed teams, evolving architectures, and millions of lines of code. Through scalable analysis, Project Streams and Modules, and differential analysis, teams can expand software quality programs without sacrificing quality or productivity. Klocwork has no cost penalty for growth, as it scales without additional license premiums.

Polyspace is often chosen for formal methods-based analysis and integration with other MathWorks tools, while Perforce QAC is selected for easy adoption, deep static analysis, strong standards compliance, and support for large codebases and complex project structures. 

The primary difference is analytical approach: Polyspace uses formal methods to mathematically prove the absence of a defined set of software issues, while Perforce Klocwork uses static analysis for deep, inter-procedural, path-sensitive control and dataflow analysis. Additionally, Klocwork supports more languages (including mixed-language C, C++, and Rust projects), enterprise scalability, continuous compliance, and static application security testing (SAST) initiatives. 

Perforce QAC is selected for teams that need deeper analysis of issues affecting both security and functional safety, as well as centralized management of compliance governance across projects. Polyspace is often used for formal verification and compliance workflows where teams must prove that specific runtime errors do not exist.  

Organizations prioritizing formal proof-based analysis often choose Polyspace, while teams needing enterprise-scale analysis, broader language and tool support, mixed-language analysis, and static application security testing (SAST) choose Perforce Klocwork. 

Alternatives to Polyspace are Perforce Klocwork, Perforce QAC, Coverity, Parasoft, and LDRA.
