Security Code Scan
A static code analyzer that detects security vulnerabilities in C# and VB.NET applications.
What is Security Code Scan?
Security Code Scan is a static application security testing (SAST) tool that detects security vulnerabilities in C# and VB.NET source code. It analyzes code for common security issues like SQL injection, cross-site scripting, and insecure deserialization patterns. The tool integrates directly into the development workflow to provide immediate feedback to developers.
.NET developers and security engineers working with C# or VB.NET applications who need to identify security vulnerabilities during development. Teams implementing DevSecOps practices in .NET environments.
Unlike generic security scanners, Security Code Scan is specifically designed for .NET languages and integrates seamlessly with Visual Studio and build pipelines. It provides fast, accurate analysis using Microsoft's Roslyn compiler platform and allows customization of security rules to match specific application requirements.
Overview
Vulnerability Patterns Detector for C# and VB.NET
Use Cases
Best For
- Identifying SQL injection vulnerabilities in .NET web applications
- Detecting cross-site scripting (XSS) issues in ASP.NET projects
- Adding security scanning to CI/CD pipelines for .NET codebases
- Enforcing secure coding standards in enterprise .NET development teams
- Finding path traversal vulnerabilities in file handling code
- Preventing insecure deserialization attacks in .NET applications
Not Ideal For
- Projects using languages other than C# or VB.NET
- Teams requiring dynamic application security testing (DAST) or runtime monitoring
- Organizations that need multi-language SAST support beyond the .NET ecosystem
- Environments where minimal dependencies and simple setup are prioritized over deep integration
Pros & Cons
Pros
Built on Microsoft's Roslyn compiler platform, enabling fast, accurate analysis directly within the development workflow, as highlighted in the key features for seamless IDE feedback.
Available as a NuGet package, Visual Studio extension, and standalone command-line runner, providing flexibility for integration into various development and build environments, as stated in the README's downloading section.
Supports external configuration files to define custom vulnerable functions and untrusted sources, allowing teams to tailor detection to specific application needs, as detailed in the README's contributing and external configuration sections.
Analyzes both C# and VB.NET code with consistent detection capabilities, ensuring broad support for .NET applications without language-specific gaps, as noted in the key features.
Cons
Only supports C# and VB.NET, excluding other .NET languages like F# and newer frameworks, which restricts its utility in polyglot or evolving .NET environments.
Debugging analysis issues requires uncommenting code lines, running multiple Visual Studio instances, and ensuring no conflicting extensions, as described in the README's debugging section, making troubleshooting cumbersome.
As a Roslyn-based analyzer, it can slow down IDE performance and build times in large projects, a common trade-off for static analysis tools that isn't explicitly addressed in the documentation.
Open Source Alternative To
Security Code Scan is an open-source alternative to the following products:
Veracode is a cloud-based application security platform that provides static analysis, dynamic analysis, and software composition analysis for vulnerabilities.
SonarQube is an open-source platform for continuous inspection of code quality, performing automatic reviews to detect bugs, vulnerabilities, and code smells.
Checkmarx is a software security company that provides static application security testing (SAST) solutions to help developers identify and fix security vulnerabilities in source code.
