Bright Data Security Basics

Overview

Security best practices for Bright Data zone credentials, API tokens, and webhook delivery. Bright Data credentials include Customer ID, zone passwords, and API tokens — all must be protected.

Prerequisites

• Bright Data zones configured
• Understanding of environment variables
• Access to Bright Data control panel

Instructions

Step 1: Credential Inventory

brd-ca.crt

Step 2: Environment Variable Security

# .env (NEVER commit)
BRIGHTDATA_CUSTOMER_ID=c_abc123
BRIGHTDATA_ZONE=web_unlocker1
BRIGHTDATA_ZONE_PASSWORD=z_pass_xyz
BRIGHTDATA_API_TOKEN=abc123def456

# .gitignore
.env
.env.local
.env.*.local

# .env.example (safe to commit — no real values)
BRIGHTDATA_CUSTOMER_ID=
BRIGHTDATA_ZONE=
BRIGHTDATA_ZONE_PASSWORD=
BRIGHTDATA_API_TOKEN=

Step 3: Zone Isolation by Environment

Create separate zones per environment so staging credentials cannot access production proxy bandwidth:

// config/brightdata.ts
const ZONE_MAP = {
  development: 'web_unlocker_dev',
  staging: 'web_unlocker_staging',
  production: 'web_unlocker_prod',
} as const;

export function getZone(): string {
  const env = process.env.NODE_ENV || 'development';
  return process.env.BRIGHTDATA_ZONE || ZONE_MAP[env] || ZONE_MAP.development;
}

Step 4: Credential Rotation

# 1. Create new API token in Bright Data CP > Settings > API tokens
# 2. Update secrets in your deployment platform
# Vercel
vercel env rm BRIGHTDATA_API_TOKEN production
vercel env add BRIGHTDATA_API_TOKEN production

# AWS
aws secretsmanager update-secret --secret-id brightdata/api-token --secret-string "new_token"

# 3. Test new credentials
curl -H "Authorization: Bearer ${NEW_TOKEN}" \
  https://api.brightdata.com/zone/get_active_zones

# 4. Revoke old token in Bright Data CP

Step 5: Git Secret Scanning

# Pre-commit hook to catch leaked credentials
# .git/hooks/pre-commit
#!/bin/bash
if git diff --cached | grep -iE '(BRIGHTDATA_ZONE_PASSWORD|BRIGHTDATA_API_TOKEN)=.{5,}'; then
  echo "ERROR: Bright Data credentials detected in staged changes"
  exit 1
fi

Step 6: Webhook Delivery Security

When using webhook delivery for Web Scraper API results:

// Validate webhook came from Bright Data
function validateWebhookSource(req: Request): boolean {
  // Bright Data sends from known IPs — check docs for current list
  // Also validate the Authorization header you configured
  const authHeader = req.headers.get('Authorization');
  return authHeader === `Bearer ${process.env.BRIGHTDATA_WEBHOOK_SECRET}`;
}

Security Checklist

• Zone passwords in environment variables, never hardcoded

• .env

  files in

  .gitignore

• Separate zones per environment (dev/staging/prod)
• API tokens rotated quarterly
• Pre-commit hook blocks credential leaks
• Webhook endpoints validate Authorization header
• HTTPS-only for all proxy connections

• brd-ca.crt

  downloaded (public cert, safe in repo)
