## 🎯 Why vet?
> **70-90% of modern software constitute code from open sources** — How do we know if it's safe?
**vet** is an open source software supply chain security tool built for **developers and security engineers** who need:
✅ **Real-time malicious package detection** — Active scanning and analysis of unknown packages
✅ **Modern SCA with actual usage analysis** — Prioritize real risks over vulnerability noise
✅ **Policy as Code** — Express security requirements using [CEL](https://cel.dev/) expressions
Hosted SaaS version available at [SafeDep Cloud](https://app.safedep.io).
Get started with [GitHub App](https://github.com/apps/safedep) and other integrations.
## ⚡ Quick Start
**Install in seconds:**
```bash
# macOS & Linux
brew install safedep/tap/vet
```
or download a [pre-built binary](https://github.com/safedep/vet/releases)
**Get started immediately:**
```bash
# Scan for malware in your dependencies
vet scan -D . --malware-query
# Fail CI on critical vulnerabilities
vet scan -D . --filter 'vulns.critical.exists(p, true)' --filter-fail
# Get API key for advanced malware detection
vet cloud quickstart
```

## 🔒 Key Features
### 🛡️ **Malicious Package Detection**
Real-time protection against malicious packages powered by [SafeDep Cloud](https://docs.safedep.io/cloud/malware-analysis).
Free for open source projects. Detects zero-day malware through active code analysis.
### 🕵️ **Smart Vulnerability Analysis**
Unlike dependency scanners that flood you with noise, `vet` analyzes your **actual code usage** to prioritize real risks.
See [dependency usage evidence](https://docs.safedep.io/vet/guides/dependency-usage-identification) for details.
### 📋 **Policy as Code**
Define security policies using CEL expressions to enforce context specific requirements:
```bash
# Block packages with critical CVEs
vet scan --filter 'vulns.critical.exists(p, true)' --filter-fail
# Enforce license compliance
vet scan --filter 'licenses.contains_license("GPL-3.0")' --filter-fail
# Require minimum OpenSSF Scorecard scores
vet scan --filter 'scorecard.scores.Maintained < 5' --filter-fail
```
### 🎯 **Multi-Ecosystem Support**
Package managers: **npm**, **PyPI**, **Maven**, **Go**, **Ruby**, **Rust**, **PHP**
Container images: **Docker**, **OCI**
SBOM formats: **CycloneDX**, **SPDX**
Source repositories: **GitHub**, **GitLab**
## 🛡️ Malicious Package Detection
**Real-time protection against malicious packages** with active scanning and behavioral analysis.
### 🚀 Quick Setup
```bash
# One-time setup for advanced scanning
vet cloud quickstart
# Scan for malware with active scanning (requires API key)
vet scan -D . --malware
# Query known malicious packages (no API key needed)
vet scan -D . --malware-query
```
**Example detections:**
- [MAL-2025-3541: express-cookie-parser](https://safedep.io/malicious-npm-package-express-cookie-parser/)
- [MAL-2025-4339: eslint-config-airbnb-compat](https://safedep.io/digging-into-dynamic-malware-analysis-signals/)
- [MAL-2025-4029: ts-runtime-compat-check](https://safedep.io/digging-into-dynamic-malware-analysis-signals/)
**Key security features:**
- ✅ Real-time analysis against known malware databases
- ✅ Behavioral analysis using static and dynamic analysis
- ✅ Zero-day protection through active code scanning
- ✅ Human-in-the-loop triaging for high-impact findings
- ✅ Public [analysis log](https://vetpkg.dev/mal) for transparency
### 🎯 Advanced Usage
```bash
# Specialized scans
vet scan --vsx --malware # VS Code extensions
