Microsoft DevSkim vs MobSF

Microsoft DevSkim is a free, MIT-licensed toolkit for security linting and static source-code analysis. It provides IDE extensions, language analyzers, and rules to help developers identify and address security vulnerabilities early. It includes built-in rules and allows teams to write their own using JSONPath, XPath, and YmlPath. Listed language support includes C, C++, C#, Cobol, Go, Java, JavaScript/TypeScript, and Python, among others. Its cross-platform .NET CLI analyzes files and directories and can be installed as a global tool or obtained as binaries for Windows, macOS, and Linux. A C# library is also available for embedding analysis in other tools. Results can be emitted as SARIF, JSON, or text; the CLI can apply suggested fixes from SARIF results and add suppression comments. The project lists extensions for Visual Studio Code and Visual Studio, and supports CI/CD in self-hosted environments. Support is limited to GitHub issues and project wiki resources. Vulnerability reports should be sent privately to Microsoft's Security Response Center rather than posted publicly.

MobSF is an open-source framework for automated mobile application security testing and penetration testing. Its static analysis examines source code and binaries for security flaws and misconfigurations before execution. Dynamic analysis runs apps in a controlled sandbox to observe runtime behavior, data flow, and API interactions, while malware analysis looks for suspicious code, permissions, and behavior. Supported inputs include Android, iOS, and Windows packages such as APK, XAPK, IPA, and APPX, plus zipped source code. REST APIs connect MobSF with CI/CD or DevSecOps pipelines; named examples include Jenkins, GitHub Actions, and GitLab CI. Reports include severity, affected files or functions, and remediation suggestions, with HTML, PDF, and JSON export options. MobSF can be installed from GitHub or with Docker, runs on Windows, Linux, or macOS, and can operate offline. The Community Edition is open source under GPL v3 and costs nothing. Dynamic analysis is limited to rooted Android versions 4.1 through 11.0, up to API 30; obfuscation and code protection can limit analysis depth.
