Snyk for security & code scanning
For security and code scanning, Snyk is our second pick of three, and it fits the shift-left goal directly: built into the Snyk CLI, it scans dependencies, code, containers, and IaC for vulnerabilities as the assistant generates or edits code. An agent can flag a finding inline and fix it before the change lands.
Semgrep leads here for fast semantic static analysis with custom rules, the tightest scan-explain-fix loop on first-party code. Snyk's edge is breadth across the supply chain: open-source dependencies, container images, infrastructure config, and secrets, the surfaces a SAST-only tool leaves uncovered.
How Snyk fits
The tools that carry security work span the supply chain. snyk_sca_scan inspects manifest files for known vulnerabilities and license issues in dependencies, snyk_code_scan runs SAST over first-party source, and snyk_secret_scan catches hardcoded API keys, tokens, and passwords before they ship. snyk_container_scan covers OS-package and app-dependency vulnerabilities in images, and snyk_iac_scan checks Terraform, Kubernetes, and CloudFormation for misconfigurations. snyk_sbom_scan analyzes an existing SBOM, snyk_aibom generates an AI bill of materials for Python projects, and snyk_package_health_check plus snyk_breakability_check tell an agent whether a fix-by-upgrade is safe. snyk_auth, snyk_logout, and snyk_trust manage the login flow and folder permission.
The honest comparison: Semgrep, the top pick, gives the fastest semantic analysis with custom rules and is the sharper tool for catching dangerous patterns in your own code. SonarQube brings the full code-quality and security platform with coverage and gates, a broader view than scanning alone. Snyk's strength is the dependency and infrastructure surface plus secret detection, so it pairs well: run Semgrep for first-party patterns and Snyk for the supply chain and config layer.
Tools you would use
| Tool | What it does |
|---|---|
| snyk_sca_scan | Software composition analysis: inspects manifest files to find known vulnerabilities and license-compliance issues in open-source dependencies (uses absolute paths). |
| snyk_code_scan | Static application security testing (SAST): analyzes first-party source code to identify security vulnerabilities. |
| snyk_container_scan | Scans container images for known vulnerabilities in OS packages and application dependencies. |
| snyk_iac_scan | Analyzes Infrastructure-as-Code files (Terraform, Kubernetes, CloudFormation, and more) for security misconfigurations. |
| snyk_sbom_scan | Analyzes an existing SBOM file for known vulnerabilities in its open-source components (components must be identified by PackageURLs). |
| snyk_secret_scan | Scans source code and configuration files to detect hardcoded secrets such as API keys, tokens, and passwords. |
| snyk_aibom | Generates an AI Bill of Materials (AIBOM) for Python projects in CycloneDX v1.6 JSON, identifying AI models and dependencies. |
| snyk_package_health_check | Retrieves package information and health metrics from Snyk's package intelligence API, including vulnerabilities and maintenance status. |
| snyk_breakability_check | Runs a breaking-change assessment for a package-version upgrade. |
| snyk_auth | Authenticates the user with Snyk, typically via a browser login flow, when a tool reports the user is not authenticated. |
FAQ
- How is Snyk different from Semgrep for security scanning?
- Semgrep, the top pick, leads on fast semantic SAST with custom rules over first-party code. Snyk covers the supply chain: snyk_sca_scan for dependencies, snyk_container_scan for images, snyk_iac_scan for config, and snyk_secret_scan for hardcoded keys. They overlap deliberately.
- Can Snyk scan infrastructure code as well as app code?
- Yes. snyk_iac_scan analyzes Terraform, Kubernetes, CloudFormation, and more for security misconfigurations, and snyk_container_scan checks container images for known vulnerabilities in OS packages and dependencies.
