Introduction
DepScanity revolutionizes dependency security management by serving as a lightweight, CLI-first Software Composition Analysis (SCA) orchestrator built with Go that seamlessly automates vulnerability scanning across .NET, Node.js, Bun, and container projects. This powerful tool transforms the chaos of fragmented dependency security into a single, deterministic truth by consolidating vulnerability findings from native scanning tools into standardized JSON and Markdown reports. With intelligent automatic stack detection, DepScanity eliminates the guesswork of identifying project types while maintaining a unified output format that simplifies security analysis across diverse technology stacks. The tool’s resilient execution ensures reliable performance even in complex environments, while its pipeline integration delivers deterministic exit codes that make security checks predictable and actionable. Designed specifically for CI/CD workflows, DepScanity transforms previously unpredictable security analysis into a reliable, automated process that developers can trust to consistently identify and report vulnerabilities across their entire dependency ecosystem.
Structure of the Solution
DepScanity’s architecture follows clean Go practices with a well-defined directory structure that separates concerns effectively. The solution’s entry point resides in cmd/depscanity, which handles CLI operations and user interaction, while internal/ houses the core implementation packages that contain the business logic and domain-specific functionality. The system’s modular design incorporates several key architectural components working in harmony: detection mechanisms scan for technology stacks by analyzing marker files and configuration artifacts, scanner implementations wrap native tools like npm audit, .NET dependency check, and container vulnerability scanners, and report generation produces standardized outputs in both JSON and Markdown formats. The architecture employs sophisticated aggregation logic that normalizes findings across different scanners into a unified data model, abstracting scanner-specific variations and providing deterministic results. Critical design patterns include tool orchestration with built-in timeout protection to prevent hanging processes, deterministic exit codes ensuring seamless CI/CD integration, and a clean separation between command-line handling and internal domain logic that follows standard Go conventions and promotes maintainability.
Supported Technologies
DepScanity provides comprehensive dependency security scanning across multiple technology ecosystems through its intelligent automatic detection system. The platform seamlessly supports four primary stacks: .NET/NuGet, Node.js, Bun, and Containerized applications. For .NET projects, DepScanity detects *.sln and *.csproj files to run dotnet list package –vulnerable scans, while Node.js applications are identified through package-lock.json files using npm audit. Bun projects are recognized via bun.lock files with bun audit scans, and containerized applications are detected through Dockerfile analysis using trivy image scanner. This intelligent detection eliminates the need for manual configuration by automatically scanning for specific marker files inherent to each technology stack. Each ecosystem’s native security tools are orchestrated and unified into a single comprehensive report, providing developers with consolidated vulnerability insights across all supported platforms. The automatic detection feature ensures effortless scanning of projects without requiring users to specify technology types, making dependency security accessible and streamlined for development teams working across diverse technological landscapes.
Installation and Setup
To install and set up DepScanity, you’ll first need to ensure your system meets the prerequisites: Go 1.21 or higher is required for building from source, along with ecosystem-specific tools such as the .NET SDK for .NET projects, Node.js/npm for Node projects, Bun for Bun projects, and Docker with Trivy for container scanning capabilities. Once you have these dependencies in place, clone the DepScanity repository from GitHub, then compile the binary using the go build command. For system-wide accessibility, you may optionally move the compiled binary to your PATH. It’s important to note that DepScanity functions as a wrapper orchestrating external tools rather than incorporating native scanners, meaning users must independently install the ecosystem-specific scanning tools they intend to use for their projects. Currently, installation is accomplished exclusively through building from source code, with the compiled binary ready for immediate use once the build process completes successfully.
Usage and Command-Line Interface
DepScanity’s command-line interface enables comprehensive security scanning of dependencies across .NET, Node.js, and container environments through the primary command syntax: `depscanity scan
Output Formats and Reports
DepScanity generates three distinct output formats to cater to different stakeholder needs and technical requirements. The primary report.md file provides a human-readable markdown summary designed for seamless integration into stakeholder communications, pull request comments, and security dashboards, offering clear visual presentation of security findings. The report.json file serves as a machine-readable comprehensive dataset containing full technical details, enabling smooth integration with downstream security tools, CI/CD platforms, and analysis systems. Additionally, the raw/ directory preserves unmodified output from each underlying scanner tool (npm audit, dotnet list package, trivy, bun audit), facilitating debugging and tool-specific analysis. A key feature of DepScanity is its finding normalization capability, which unifies security findings across heterogeneous tools into a standardized format, effectively abstracting vendor-specific differences regardless of whether vulnerabilities originate from .NET, Node.js, Bun, or container scanning. These reports are systematically correlated with deterministic exit codes: 0 indicates no vulnerabilities exceeding configured thresholds, 2 signals findings that trigger failure conditions, and 3 denotes scanner execution errors, ensuring consistent and predictable integration into automated workflows.
CI/CD Integration
DepScanity seamlessly integrates into CI/CD pipelines through its deterministic exit code system, providing reliable automation across diverse deployment environments. The tool returns specific exit codes: 0 for successful scans with no findings exceeding thresholds, 1 for application errors or invalid arguments, 2 for vulnerability threshold violations that trigger pipeline failures, and 3 for scanner execution failures. This deterministic approach ensures consistent reproducible results crucial for automated workflows. Teams can configure severity thresholds using the –fail-on flag to specify low, medium, high, or critical levels, allowing flexible failure criteria that match organizational security policies. The tool generates unified reports in both machine-readable JSON and human-readable Markdown formats, perfect for PR comments and dashboard integration. Built-in timeout controls with 600-second defaults prevent hanging processes while external tool failures are isolated to prevent orchestrator crashes. During typical integration, teams invoke depscanity as a pipeline step with target path, severity threshold, and output directory parameters. The tool intelligently manages detector discovery and native scanner execution while maintaining proper exit code flow control for seamless pipeline integration. Explicitly designed for CI/CD workflows, DepScanity delivers reliable, automated security analysis across GitHub Actions, GitLab CI, Jenkins, and other platforms, making dependency security a seamless part of modern development practices.
Best Practices
To maximize DepScanity’s effectiveness in development workflows, organizations should implement systematic scan strategies starting with pull request integration to catch vulnerabilities early in the development cycle. Running daily scheduled scans for active projects and conducting pre-release security audits ensures comprehensive coverage while maintaining development velocity. When handling false positives, teams should systematically review and document exceptions, utilize suppression files or exclude patterns judiciously, and maintain detailed audit trails of all security decisions to support compliance and continuous improvement. Severity thresholds should be calibrated based on project maturity and risk tolerance, beginning with high/critical severity filters for new implementations and gradually tightening to medium severity as processes mature and teams develop expertise. Integration of DepScanity early in the development lifecycle transforms security checks into standard code review practices, while automated reporting enables teams to track vulnerability trends and measure improvement over time. Effective team collaboration requires establishing clear ownership for security findings, creating standardized runbooks for common vulnerability types, and fostering a security-first culture that values both protection and development efficiency. Regular tool updates and dependency version reviews ensure continued effectiveness, while maintaining the delicate balance between robust security coverage and sustainable development practices that support organizational agility.
