FAQPage Schema

How does static analysis find security vulnerabilities in source code?▼

Static analysis identifies security vulnerabilities by performing deep semantic code analysis to parse code structure and detect potential flaws across various programming languages.

How do I scan my project for bugs using semantic code analysis?▼

To scan your project for bugs, run the semantic code analysis engine in your current directory to automatically identify security vulnerabilities, anti-patterns, and potential code quality issues.

Can I use semantic code analysis to scan pull requests in my CI/CD pipeline?▼

Yes, you can integrate semantic code analysis into your CI/CD pipeline to automatically scan pull requests, preventing insecure code with security vulnerabilities from merging.

What do I need to perform semantic code analysis for vulnerability detection?▼

To perform vulnerability detection, you need specific query packs and analysis engines to parse code structure and identify potential flaws across various programming languages.

What is the difference between static analysis and semantic code analysis for code quality?▼

Semantic code analysis goes deeper than basic static analysis by parsing code structure to understand logic and identify complex security vulnerabilities, bugs, and anti-patterns proactively.

Are there limitations when using semantic code analysis for proactive code quality assurance?▼

Limitations of semantic code analysis include the requirement for specific query packs and analysis engines, making it dependent on having the correct environment setup to parse code structure accurately.
