Modern software development demands robust security testing solutions to protect applications from vulnerabilities and threats. Two prominent platforms leading this space are Checkmarx and Semgrep, each offering distinct approaches to application security testing. Organizations face critical decisions when choosing between these solutions, as each platform brings unique strengths and capabilities to the table. This comprehensive comparison examines every aspect of both platforms, from their core technologies and detection capabilities to pricing models and enterprise features. Understanding these differences helps development teams, security professionals, and business leaders make informed decisions about their application security investments in 2026.

Platform Overview and Core Technologies

Checkmarx stands as a comprehensive application security platform offering multiple testing methodologies within a unified solution. The platform integrates Static Application Security Testing (SAST), Software Composition Analysis (SCA), Infrastructure as Code (IaC) scanning, and Dynamic Application Security Testing (DAST) capabilities.

Semgrep takes a different approach, focusing primarily on static analysis with a lightweight, rule-based engine. The platform emphasizes speed and developer-friendly integration while maintaining accuracy in vulnerability detection.

Checkmarx Architecture and Technology Stack

Checkmarx One represents the latest evolution of the platform, built on cloud-native architecture. The system utilizes advanced parsing engines that understand code semantics across multiple programming languages. Machine learning algorithms enhance detection accuracy while reducing false positives.

The platform’s multi-engine approach combines different analysis techniques:

• Semantic analysis for understanding code context
• Data flow analysis tracking variable paths
• Control flow analysis examining execution paths
• Pattern matching for known vulnerability signatures

Checkmarx supports over 25 programming languages including Java, C#, JavaScript, Python, Go, and emerging languages like Kotlin and Swift. The platform’s engine can analyze both source code and compiled bytecode.

Semgrep’s Lightweight Analysis Engine

Semgrep operates on a fundamentally different principle, using a pattern-based approach that resembles grep but with semantic understanding. The engine parses code into Abstract Syntax Trees (AST) and applies rules written in YAML format.

Key technological advantages include:

• Fast execution times due to lightweight architecture
• Language-agnostic rule engine
• Simple rule creation and customization
• Minimal resource consumption

Semgrep supports 30+ programming languages with consistent rule syntax across all languages. The platform’s strength lies in its ability to find complex patterns beyond traditional security vulnerabilities.

Security Testing Capabilities Comparison

Both platforms excel in different aspects of security testing, reflecting their distinct architectural philosophies and target use cases.

Static Application Security Testing (SAST)

Checkmarx provides enterprise-grade SAST capabilities with deep code analysis.
