+# Nancy Vulnerability Scanner Setup
+
+## Overview
+
+Nancy is an optional vulnerability scanner from Sonatype that checks your Go dependencies against the OSS Index for known security vulnerabilities. It's integrated into the CI/CD pipeline but requires authentication to function.
+
+## Current Configuration
+
+Nancy is configured with `continue-on-error: true` in the GitHub Actions workflow, meaning:
+- ✅ The CI pipeline will **not fail** if Nancy authentication is missing
+- ✅ Gosec security scanner still runs and provides security scanning
+- ⚠️ Nancy will show a warning but won't block your builds
+
+## Why Nancy Requires Authentication
+
+Nancy connects to the [Sonatype OSS Index](https://ossindex.sonatype.org/) which requires a free account to prevent abuse and rate limiting.
+
+## How to Enable Nancy (Optional)
+
+If you want to enable full vulnerability scanning with Nancy, follow these steps:
+
+### 1. Create a Free OSS Index Account
+
+1. Go to https://ossindex.sonatype.org/
+2. Click "Sign Up" and create a free account
+3. Verify your email address
+
+### 2. Get Your API Token
+
+1. Log in to OSS Index
+2. Go to your account settings
+3. Generate an API token
+4. Copy your username and token
+
+### 3. Add GitHub Secrets
+
+Add the following secrets to your GitHub repository:
+
+1. Go to your repository on GitHub
+2. Navigate to **Settings** → **Secrets and variables** → **Actions**
+3. Click **New repository secret**
+4. Add these two secrets:
+   - Name: `NANCY_USERNAME`, Value: your OSS Index username
+   - Name: `NANCY_TOKEN`, Value: your OSS Index API token
+
+### 4. Update the Workflow (Optional)
+
+If you added the secrets, you can update `.github/workflows/ci.yml` to use them:
+
+```yaml
+      - name: Run Nancy vulnerability scanner
+        if: ${{ !env.ACT }}
+        continue-on-error: true
+        env:
+          NANCY_USERNAME: ${{ secrets.NANCY_USERNAME }}
+          NANCY_TOKEN: ${{ secrets.NANCY_TOKEN }}
+        run: |
+          go install github.com/sonatype-nexus-community/nancy@latest
+          if [ -n "$NANCY_TOKEN" ]; then
+            go list -json -deps ./... | nancy sleuth --username "$NANCY_USERNAME" --token "$NANCY_TOKEN"
+          else
+            go list -json -deps ./... | nancy sleuth || echo "⚠️ Nancy scan skipped - requires OSS Index authentication."
+          fi
+```
+
+## Local Usage
+
+To run Nancy locally:
+
+### Without Authentication (Limited)
+```bash
+go install github.com/sonatype-nexus-community/nancy@latest
+go list -json -deps ./... | nancy sleuth
+```
+
+### With Authentication (Recommended)
+```bash
+# Set environment variables
+export NANCY_USERNAME="your_username"
+export NANCY_TOKEN="your_token"
+
+# Run Nancy
+go list -json -deps ./... | nancy sleuth --username "$NANCY_USERNAME" --token "$NANCY_TOKEN"
+```
+
+Or add to your `.env` file (don't commit this):
+```bash
+NANCY_USERNAME=your_username
+NANCY_TOKEN=your_token
+```
+
+## Alternative: Use Make Command
+
+The Makefile includes a vulnerability scan command:
+
+```bash
+make vulnerability-scan
+```
+
+This will attempt to run Nancy. If you have credentials configured, it will use them.
+
+## What Nancy Checks
+
+Nancy scans your Go dependencies (`go.mod` and transitive dependencies) against the OSS Index database for:
+- Known CVEs (Common Vulnerabilities and Exposures)
+- Security advisories
+- Vulnerability severity scores
+- Affected version ranges
+- Remediation recommendations
+
+## Current Security Coverage
+
+Even without Nancy, your CI pipeline includes:
+- ✅ **Gosec** - Static analysis security scanner for Go code
+- ✅ **Go Module Checksums** - Ensures dependency integrity
+- ✅ **Unit Tests** - Including security-focused tests
+- ✅ **Code Review** - Manual security review process
+
+Nancy adds an additional layer by checking for known vulnerabilities in dependencies.
+
+## Troubleshooting
+
+### "401 Unauthorized" Error
+This means Nancy couldn't authenticate with OSS Index. Either:
+- You haven't set up credentials (this is fine - it won't break CI)
+- Your credentials are incorrect
+- Your API token has expired
+
+### Rate Limiting
+Without authentication, OSS Index has strict rate limits. If you hit them:
+- Wait a few minutes and try again
+- Consider setting up authentication (free and unlimited)
+
+### Nancy Installation Issues
+If Nancy fails to install:
+```bash
+# Clear Go module cache
+go clean -modcache
+
+# Reinstall
+go install github.com/sonatype-nexus-community/nancy@latest
+```
+
+## Recommendations
+
+### For Open Source Projects
+- Authentication is optional but recommended
+- Use GitHub secrets to protect credentials
+- Document in your CONTRIBUTING.md if you require Nancy to pass
+
+### For Private/Enterprise Projects
+- **Strongly recommended** to set up authentication
+- Consider making Nancy a required check (remove `continue-on-error`)
+- Regular vulnerability scanning is a security best practice
+
+### For Personal Projects
+- Authentication is optional
+- Gosec provides good security coverage without it
+- Enable Nancy if you want comprehensive dependency scanning
+
+## Resources
+
+- [Nancy GitHub Repository](https://github.com/sonatype-nexus-community/nancy)
+- [OSS Index](https://ossindex.sonatype.org/)
+- [Sonatype Documentation](https://ossindex.sonatype.org/doc/rest)
+- [GitHub Actions Secrets](https://docs.github.com/en/actions/security-guides/encrypted-secrets)
+
+## Summary
+
+Nancy is **optional** and **non-blocking** in this project's CI pipeline. The security-scan job will pass regardless of Nancy's status. If you want full vulnerability scanning, follow the setup steps above. Otherwise, Gosec provides excellent security scanning for your code.
