What Klocwork does
Klocwork is a static application security testing (SAST) product operated as a brand within Perforce Software Inc., a privately held software company. The tool performs inter-procedural dataflow analysis on source code written in C, C++, C#, Rust, Java, JavaScript, Python, and Kotlin, identifying security vulnerabilities, reliability defects, and compliance violations early in the development lifecycle. Its core technical differentiators include differential/incremental analysis that processes only changed files while delivering full-codebase results, project streams for managing multi-branch codebases, and the Perforce Validate platform, which centralizes analysis results, trends, and compliance rule configurations across an organization.
The product is sold via an enterprise field-sales motion to mission-critical industries — automotive, aerospace and defense, medical technology, and industrial automation — where compliance with functional safety and security standards (ISO 26262, IEC 61508, EN 50716, IEC 62304, DO-178C, DISA STIG, MISRA C/C++, AUTOSAR C++ 14, CWE, OWASP, CERT, PCI DSS) is mandatory. Klocwork holds TÜV-SüD functional safety certification across automotive, industrial, rail, and medical device standards, alongside ISO 9001 and ISO 27001 certifications, providing a regulatory qualification moat. Native plugins for Visual Studio, Eclipse, and IntelliJ, plus a REST API for CI/CD automation, support shift-left security integration, and a 2025-launched AI-Assisted Code Remediation feature (with a GitHub Copilot integration) leverages external LLMs to suggest contextual code fixes for identified vulnerabilities. Pricing is quote-based and not publicly disclosed, with revenue derived from enterprise subscription licenses plus professional services for onboarding and ongoing support; a free trial is available for evaluation.

Products and services
- Perforce Klocwork Perforce Klocwork is a static application security testing (SAST) tool that identifies security vulnerabilities, reliability issues, and compliance violations in source code across C, C++, C#, Rust, Java, JavaScript, Python, and Kotlin. It integrates into DevSecOps workflows to provide early defect detection at scale, with support for massive multi-branch codebases, and is targeted at enterprise software teams in regulated industries such as automotive, aerospace, defense, medical technology, and industrial automation.
- Perforce Validate Platform The Perforce Validate platform is a centralized web-based store of analysis results from Perforce Static Analysis solutions (Klocwork and QAC). It provides analysis data, trends, and configurations for codebases across an organization, enabling teams to define QA and compliance rule configurations, identify issues and deviations, and review code by project and section.
Quantifiable outcome
- Teams integrating Klocwork SAST into CI/CD pipelines catch costly defects before they spread and shorten development cycles with early remediation.

Klocwork competitors and assessment
Company assessmentDirect peers
- Synopsys Coverity: Coverity is Synopsys's enterprise SAST platform with deep C/C++ analysis, widely used in automotive, aerospace, and embedded safety-critical development. It is Klocwork's closest historical head-to-head competitor for mission-critical static analysis at large enterprises.
- Checkmarx: Checkmarx provides enterprise SAST, SCA, and application security posture management. It is a direct competitor for multi-language static analysis at large enterprises, often evaluated alongside Klocwork in AppSec procurements.
- Veracode: Veracode offers a SaaS application security platform including SAST, DAST, and SCA, targeting enterprise AppSec programs. It competes with Klocwork for enterprise security and compliance budget in regulated industries.
- GrammaTech CodeSonar: CodeSonar is GrammaTech's static analysis tool focused on embedded C/C++ and safety-critical software with deep support for MISRA, DO-178C, and IEC 61508. It directly competes with Klocwork for the same embedded and mission-critical customer base.
- Parasoft: Parasoft provides static analysis (C/C++test, dotTEST, Jtest) and software testing tools with strong automotive (MISRA, AUTOSAR, ISO 26262) coverage. It overlaps directly with Klocwork in regulated embedded development verticals.
- Snyk Code: Snyk Code is Snyk's developer-first SAST offering integrated with its broader security platform. It directly competes with Klocwork for modern enterprise developer-security budget, particularly where cloud-native and DevSecOps workflows are prioritized.
- SonarSource (SonarQube): SonarSource provides multi-language static code analysis and code quality scanning via SonarQube and SonarCloud, overlapping directly with Klocwork's multi-language SAST offering for enterprise developers. It is a primary competitor in CI/CD-integrated static analysis.
Broad incumbents
- GitHub Advanced Security: GitHub Advanced Security bundles CodeQL-based SAST, secret scanning, and dependency review into the GitHub enterprise platform. As a broad incumbent with deep CI/CD distribution, it increasingly competes with Klocwork at the lower end of enterprise SAST.
- OpenText Fortify: Fortify (now under OpenText) is an enterprise application security suite covering SAST, DAST, and runtime analysis. It competes with Klocwork in regulated industries as part of a broader portfolio from a large incumbent vendor.
Emerging players
- Semgrep: Semgrep offers lightweight, open-source-rooted SAST with a strong developer experience and custom rule authoring. It is an emerging alternative to Klocwork in cloud-native and DevSecOps-first enterprises, though with less depth in embedded C/C++ safety-critical workflows.
