Klocwork Key Features

Find Security Vulnerabilities with SAST

Use Klocwork static application security testing (SAST) for DevOps (DevSecOps). Our security standards identify security vulnerabilities – helping to find and fix security issues early and proving compliance to internationally recognized security standards.

  • DevSecOps: Klocwork integrates with CI/CD tools, containers, cloud services, and machine provisioning making automated security testing easy.
  • Security Standards:  CWE, OWASP, CERT, PCI DSS, DISA STIG, and ISO/IEC TS 17961.
  • Security Vulnerability Detection: SQL Injection, Tainted Data, Buffer Overflow, Vulnerable Coding Practices, and many more.
  • Bug, Quality Issue, and Code Smell Detection: Null Pointer Dereferences/Exceptions, Memory/Resource Leaks, Uncaught Exceptions, and many more.

Project Streams

Project Streams provides easy management of shared code bases that have multiple variants or branches by simplifying project rule configuration, issue management, defect citing, reporting, and efficient data storage of analysis data.

Creating streams provides the following benefits:

  • Assign a single project rule configuration to all variants.
  • Issues common to multiple variants are automatically kept in sync and only require citing once.
  • Easily identify identical issues across multiple streams and issues unique to a specific stream.
  • Generate reports on individual streams for compliance, functional safety, or other evidential purposes.
  • More convenient organization and efficient storage of analysis data.

DevOps Ready

Klocwork tools are designed with Continuous Integration  and Continuous Delivery foremost in our thinking, which makes it easy to include static code analysis as part of your CI/CD pipelines.

Differential Analysis: Using system context data from the Klocwork Server, it is possible to analyze only the files that changed while also providing differential analysis results as if the entire system had been analyzed. This provides you with the shortest possible analysis times.

Easy to Automate: Klocwork tools have common command line interfaces, the Klocwork defect data can be accessed via a REST API and all output formats use standard formats, such as XML, JSON, and PDF.

Containerized Builds: Klocwork can be run within containerized and Cloud build systems and supports the provisioning of machine instances as required. Providing maximum flexibility and opportunity to use internal or external Cloud services for code analysis.

Control, Collaboration, and Reporting

The Klocwork Validate platform is a centralized store of analysis data, trends, metrics, and configurations for codebases across the organization — accessed through a web browser.

The dashboard is highly customizable, enabling your developers, managers, and other stakeholders to:
  • Define global or project-specific QA and security objectives and rule configurations.
  • Control access permissions and approval workflows. 
  • View trending and metrics data for project quality and compliance.
  • Produce compliance and security reports.
  • Prioritize defects based on severity, location, and lifecycle.
  • Use Smart Rank to assist developers in prioritizing fixes based on defect likelihood, which when combined with issue severity, provides an overall vulnerability risk score.
  • Distinguish new issues from legacy code issues.
  • Push backlog issues to Change Control systems.
  • Import and integrate Helix QAC findings to the Validate platform to view and manage consolidated analysis results in a single dashboard.

Designed for Developers

By seamlessly integrating static code analysis with the rest of your development toolset, Klocwork will shift-left defect detection and improve developer adoption as a tool for developer training and increasing productivity.

No User Configuration: Klocwork provides out of the box support for hundreds of compilers and cross-compilers, so build integration is automatic.

Easy to Use: Plugins for popular IDEs (including Microsoft Visual Studio, Eclipse, IntelliJ, and more).

Connected Desktop: Local code changes made using the connected desktop plugins provide immediate differential analysis results within IDEs.

Detailed Feedback and Help: Intraprocedural defects and coding violations are identified by severity of risk. For each defect and coding violation, you will receive detailed information of cause with rich, context-sensitive help and guidance on remediation. This allows for easily accessible opportunities for understanding and learning.

In addition, Klocwork features a Secure Code Warrior integration, which provides you with software security lessons and training tools for many common development languages as you write code.

Custom Rules: A graphical custom checker creation tool makes the implementation of project- or organization-specific rule quick and easy — further enriching the learning opportunities.

Architectural Analysis: Klocwork also integrates with architectural visualization and enforcement tools like Structure 101 to allow users to further improve the overall quality and maintainability of their codebase through clean and correct dependencies.

Who Uses Klocwork?

Aerospace & Defense

Aerospace, defense, and military organizations use embedded software every day. Making sure that software is safe, secure, and reliable is critical. This puts developers under pressure to produce software without any defects.

Large codebases and complex systems make this a challenge. Tough compliance requirements make it even more difficult. With Klocwork, airborne systems developers can easily prove compliance and develop quality systems.


Energy Technology

Energy and utilities product development teams need to ensure functional safety compliance, meet industry regulations as well as mitigate potential security vulnerabilities and coding errors. This can be a significant challenge for teams to effectively meet.

With Klocwork, energy and utilities product development teams can easily comply with coding standards, identify potential risks, and have visibility into code compliance.


Embedded Development

Managing the increase in digital assets is essential for the efficient design and development of embedded systems. All of those processes need to happen under strict compliance guidelines. For quality-critical industries, code needs to comply with coding standards and industry requirements. And, Klocwork can prove that your code is compliant.


Medical Device

The quality of software embedded in medical devices can mean the difference between life and death. Because of this, there is increasing scrutiny for both safety and security in devices.

By using Klocwork, you'll be able to meet ever-changing government regulations, and verify that your medical devices are safe, reliable, and efficient.



Automotive software development requires more than 100 million lines of code. What’s more, the installed embedded software is generally developed independently from the rest of the automobile.

Because of this, development teams must be able to effectively manage a unique set of challenges. With Klocwork, development teams are able to collaborate on projects, and ensure that their code is high quality and meets regulatory compliance.
