Bulk migrate WAF (Web Application Firewall) rules from various providers to Vercel.

We currently support two modes:

docs/                        # Detailed guides (credentials, exports, CI/CD)
  scripts/
  vercel-bulk-waf-rules.sh   # Main script
  rollback.sh                # Backup & restore operations
  exports/                   # WAF migration scripts (Cloudflare, Akamai, Fastly, AWS)
  tests/                     # Test fixtures and test scripts
  examples/                  # CI/CD workflow examples (GitHub Actions)

Option A: Vercel CLI login (recommended for local use)

cd /path/to/your/vercel/project
vercel link    # Creates .vercel/project.json (one-time)
vercel login   # Authenticate (one-time)

Option B: Token-based (required for CI/CD)

export VERCEL_TOKEN="your-vercel-api-token"
export PROJECT_ID="prj_xxxxxxxxxxxx"      # Or auto-detected from .vercel/project.json
export TEAM_ID="team_xxxxxxxxxxxx"        # Optional, for team projects

Need help? Run ./scripts/vercel-bulk-waf-rules.sh setup for guided setup instructions.

DRY_RUN=true RULE_MODE=deny ./scripts/vercel-bulk-waf-rules.sh apply vendor-ips.csv

Interactive Mode (recommended for first-time setup):

./scripts/vercel-bulk-waf-rules.sh apply vendor-ips.csv

The script will prompt you to choose your intended behavior:

Select rule mode:

  1) allowlist  - Block ALL traffic except listed IPs
                  Use for: Private apps, vendor-only access

  2) bypass     - Bypass WAF for listed IPs, allow all other traffic
                  Use for: Public apps with vendor integrations

Enter choice [1-2]:

Explicit Mode (for CI/CD or scripting):

# Deny mode - Block all except listed IPs
RULE_MODE=deny ./scripts/vercel-bulk-waf-rules.sh apply vendor-ips.csv

# Bypass mode - Bypass WAF for listed IPs
RULE_MODE=bypass ./scripts/vercel-bulk-waf-rules.sh apply vendor-ips.csv

Note: In non-interactive environments (CI/CD), you must set RULE_MODE explicitly or the script will exit with an error.

The script uses the vercel api CLI command (vercel@50.5.1+) and provides:

• Bulk IP management: Apply hundreds of IPs from CSV in one command
• CIDR optimization: Automatically aggregate contiguous IPs into CIDR ranges
• Two auth methods: vercel login for local use, VERCEL_TOKEN for CI/CD
• Chunking support: Automatically splits large IP lists across multiple rules (75 IPs per rule limit)
• Dry run mode: Preview changes before applying

Detailed guides are available in the docs/ folder:

This tool creates a custom firewall rule with behavior based on the selected mode:

1. Uses the ninc (NOT IN) operator to match IPs not in your list
2. Applies a deny action to block those IPs
3. Rule name: IP Allowlist - Auto-managed

1. Uses the inc (IN) operator to match IPs in your list
2. Applies a bypass action to skip WAF/security checks
3. Rule name: IP Bypass - Auto-managed

Both modes support updating the rule in place as your IP list changes.

• ip (required): IPv4 address or CIDR range
• vendor_name (optional): Vendor name for tracking
• notes (optional): Additional notes

Note: Only IPv4 is supported. IPv6 addresses will be rejected.

Export scripts are available in the scripts/exports/ directory to help migrate IP-based WAF rules from other providers.

# Export from Cloudflare
export CF_API_TOKEN="your-cloudflare-token"
./scripts/exports/cloudflare-export.sh --account abc123def456

# Import to Vercel (choose your mode)
RULE_MODE=bypass ./scripts/vercel-bulk-waf-rules.sh apply cloudflare_ips.csv

See docs/cloudflare-export.md for details.

# Export from Akamai
./scripts/exports/akamai-export.sh --list-all
./scripts/exports/akamai-export.sh --network-list 38069_VENDORIPS

# Import to Vercel (choose your mode)
RULE_MODE=bypass ./scripts/vercel-bulk-waf-rules.sh apply akamai_ips.csv

See docs/akamai-export.md for details.

# Export from Fastly Next-Gen WAF (Signal Sciences API)
export SIGSCI_EMAIL="your-email@example.com"
export SIGSCI_TOKEN="your-api-token"
./scripts/exports/fastly-export.sh --whitelist mycorp mysite

# Or use Fastly NGWAF API
export FASTLY_API_TOKEN="your-fastly-token"
./scripts/exports/fastly-export.sh --account-list list_abc123

# Import to Vercel (choose your mode)
RULE_MODE=bypass ./scripts/vercel-bulk-waf-rules.sh apply fastly_ips.csv

See docs/fastly-export.md for details.

# Configure AWS credentials
export AWS_PROFILE=my-profile
export AWS_DEFAULT_REGION=us-west-2

# Discover and export IP Sets
./scripts/exports/aws-waf-export.sh --list-ip-sets
./scripts/exports/aws-waf-export.sh --ip-set vendor-allowlist a1b2c3d4-5678-90ab-cdef-EXAMPLE11111

# Or export all IP Sets at once
./scripts/exports/aws-waf-export.sh --all-ip-sets

# Import to Vercel (choose your mode)
RULE_MODE=bypass ./scripts/vercel-bulk-waf-rules.sh apply aws_waf_ips.csv

Note: This script supports AWS WAF v2 (WAFV2) only. AWS WAF Classic (v1) was sunset on September 30, 2025. See the migration guide if you need to migrate Classic resources first.

See docs/aws-waf-export.md for details.

# Create backup
./scripts/vercel-bulk-waf-rules.sh backup

# Disable temporarily
./scripts/vercel-bulk-waf-rules.sh disable

# Remove completely
./scripts/vercel-bulk-waf-rules.sh purge

See docs/ci-cd-integration.md for complete examples for:

• GitHub Actions
• GitLab CI
• CircleCI
• Azure DevOps
• AWS CodePipeline

1. Backup First: Run ./scripts/vercel-bulk-waf-rules.sh backup before making changes
2. Dry Run: Always preview with DRY_RUN=true
3. Test on Non-Production: Test on a staging project first
4. Include Your IP: Make sure to include your office/VPN IPs!

• Store tokens in a secrets manager, not in env files
• Use project-scoped tokens when possible
• Enable AUDIT_LOG for compliance tracking
• Review IP lists regularly to remove stale entries

1. Use Vercel Dashboard to disable the rule:

   • Go to Project → Settings → Security → Firewall
   • Find the "IP Allowlist - Auto-managed" rule
   • Toggle it off or delete it

2. Or use the API from an allowed IP:

   ./scripts/vercel-bulk-waf-rules.sh disable
