HubSpot CMS PCI Compliance

Bottom Line Up Front

HubSpot CMS can be configured for HubSpot PCI compliance when properly implemented with payment processing integrations. Your e-commerce site on HubSpot can achieve SAQ A or SAQ A-EP compliance by leveraging tokenization and hosted payment fields, keeping sensitive cardholder data completely out of your CMS environment. This guide covers the technical implementation required to maintain PCI compliance while using HubSpot’s content management and e-commerce capabilities.

Technical Overview

HubSpot CMS operates as a fully hosted platform that never directly handles or stores cardholder data when properly configured. The platform’s architecture relies on external payment processors and tokenization services to maintain complete isolation from the cardholder data environment (CDE).

Architecture Considerations

Your HubSpot implementation sits outside the CDE through several key architectural decisions:

Payment Flow Isolation: HubSpot integrates with PCI-compliant payment gateways like Stripe, PayPal, or Square. These integrations use JavaScript libraries that create iframe-based payment forms, ensuring card data flows directly from the customer’s browser to the payment processor without touching HubSpot servers.

API Token Management: HubSpot stores only API credentials and payment tokens – never raw PANs. These tokens are merchant-specific and useless if compromised, as they can only be used with your specific merchant account.

Content Delivery Architecture: HubSpot’s global CDN and hosting infrastructure provide built-in security controls including DDoS protection, WAF capabilities, and automatic TLS encryption for all custom domains.

Industry Standards Beyond PCI

HubSpot maintains SOC 2 Type II certification and implements security controls that exceed basic PCI requirements. Their infrastructure includes:

  • Continuous security monitoring and intrusion detection
  • Regular third-party penetration testing
  • Automated vulnerability management
  • Role-based access control with SSO support
  • Comprehensive audit logging

These controls create defense-in-depth layers that protect your e-commerce implementation even though cardholder data never enters the HubSpot environment.

PCI DSS Requirements Addressed

When properly configured, HubSpot CMS implementations address several PCI DSS requirements through architectural design:

Requirement 1 & 2: Firewall and System Configuration

HubSpot’s managed infrastructure handles firewall configuration and system hardening. Your responsibility shifts to:

  • Configuring HubSpot user access controls
  • Managing API key security
  • Implementing proper domain and SSL certificate configuration

Requirement 3: Protect Stored Cardholder Data

Critical: HubSpot must never store cardholder data. Achieve this through:

  • Using only tokenized payment references
  • Implementing hosted payment fields (Stripe Elements, PayPal Checkout)
  • Never collecting card data in HubSpot forms
  • Configuring proper field validation to reject card numbers

Requirement 6: Secure Development

HubSpot provides:

  • Automatic platform security updates
  • Built-in XSS and CSRF protection
  • Content Security Policy (CSP) headers
  • Regular security patches without merchant intervention

Your team must:

  • Follow secure coding practices for custom modules
  • Review and sanitize all user inputs
  • Implement proper error handling that doesn’t expose system details
  • Use HubSpot’s serverless functions for any custom payment logic

Requirement 8: Access Control

Configure HubSpot’s access controls to meet PCI requirements:

  • Enforce unique user IDs (no shared accounts)
  • Implement two-factor authentication for all users
  • Configure role-based permissions
  • Regular access reviews and deprovisioning

SAQ Type Determination

Your HubSpot implementation typically qualifies for:

SAQ A: If using only redirect-based payment methods where customers leave your site completely

SAQ A-EP: If using JavaScript-based payment forms (most common with Stripe Elements or similar)

Never SAQ D: Properly configured HubSpot implementations should never require full SAQ D

Implementation Guide

Step 1: Payment Gateway Selection and Configuration

Choose a PCI-compliant payment processor that offers hosted payment fields:

“`javascript
// Example: Stripe Elements integration in HubSpot


“`

Step 2: HubSpot Form Configuration

Configure forms to explicitly reject card data:

“`javascript
// HubSpot form validation to prevent card data entry
window.addEventListener(‘message’, event => {
if(event.data.type === ‘hsFormCallback’ && event.data.eventName === ‘onFormSubmit’) {
// Validate no credit card patterns in form data
const formData = event.data.data;
const cardPattern = /b(?:d[ -]*?){13,16}b/;

for (let field in formData) {
if (cardPattern.test(formData[field])) {
// Prevent submission and show error
event.preventDefault();
alert(‘Credit card data cannot be entered in this form’);
return false;
}
}
}
});
“`

Step 3: Checkout Flow Implementation

Implement a PCI-compliant checkout flow using HubSpot’s commerce tools:

1. Product catalog management in HubSpot CMS
2. Cart functionality using HubDB or custom objects
3. Payment collection via embedded payment processor iframe
4. Order confirmation and receipt generation in HubSpot

Step 4: API Integration Security

Secure your payment processor API credentials:

“`python

HubSpot Serverless Function for payment processing

import os
import stripe

def main(event):
# Retrieve API key from environment variables
stripe.api_key = os.environ[‘STRIPE_SECRET_KEY’]

# Process payment using token from client
payment_token = event[‘token’]
amount = event[‘amount’]

try:
charge = stripe.Charge.create(
amount=amount,
currency=’usd’,
source=payment_token,
description=’HubSpot order’
)
return {
‘statusCode’: 200,
‘body’: {‘success’: True, ‘charge_id’: charge.id}
}
except Exception as e:
return {
‘statusCode’: 400,
‘body’: {‘success’: False, ‘error’: ‘Payment failed’}
}
“`

Step 5: Content Security Configuration

Configure CSP headers for payment pages:

“`javascript
// HubSpot module meta.json
{
“content_security_policy”: {
“script-src”: [“‘self'”, “https://js.stripe.com”],
“frame-src”: [“‘self'”, “https://js.stripe.com”],
“connect-src”: [“‘self'”, “https://api.stripe.com”]
}
}
“`

Testing and Validation

Compliance Verification Checklist

Data Flow Testing:

  • Verify no card data in HubSpot forms using browser developer tools
  • Check all API calls to ensure only tokens are transmitted
  • Review HubSpot activity logs for absence of card data

Security Control Validation:

  • Test form validation rejects card number patterns
  • Verify SSL/TLS configuration on all pages
  • Confirm payment fields are properly isolated in iframes

Evidence Collection for Compliance

Document these items for your compliance file:

  • Screenshot of payment form showing iframe implementation
  • Network traffic logs showing token-only transmission
  • HubSpot user access audit reports
  • Configuration screenshots of security settings

Penetration Testing Considerations

Include these HubSpot-specific tests:

  • Attempt to submit card data through various form fields
  • Test for client-side validation bypass
  • Verify API endpoint security
  • Check for information disclosure in error messages

Operational Maintenance

Monthly Tasks

Access Review:

  • Audit HubSpot user list
  • Verify 2FA enforcement
  • Remove terminated employees
  • Review API key usage

Security Monitoring:

  • Review HubSpot security center alerts
  • Check for unusual API activity
  • Monitor form submission logs
  • Verify SSL certificate validity

Quarterly Tasks

Configuration Review:

  • Validate payment integration settings
  • Test form validation rules
  • Review and update CSP policies
  • Document any platform changes

Vulnerability Management:

  • Review HubSpot platform updates

Troubleshooting

Common Implementation Issues

Payment Form Not Loading:
“`javascript
// Check Content Security Policy
// Solution: Add payment processor domain to CSP
“script-src”: [“‘self'”, “https://js.stripe.com”, “https://checkout.stripe.com”]
“`

Token Creation Failures:

  • Verify API keys are correctly configured
  • Check CORS settings on payment processor
  • Ensure proper error handling in serverless functions

Form Validation Bypasses:

  • Implement server-side validation in addition to client-side
  • Use HubSpot workflows to flag suspicious submissions
  • Regular expression patterns must cover all card formats

Performance Optimization

Lazy Loading Payment Scripts:
“`javascript
// Load payment scripts only on checkout pages
if (window.location.pathname.includes(‘/checkout’)) {
const script = document.createElement(‘script’);
script.src = ‘https://js.stripe.com/v3/’;
script.async = true;
document.head.appendChild(script);
}
“`

Legacy System Integration

When connecting HubSpot to legacy systems:

  • Use HubSpot’s Operations Hub for data transformation
  • Implement middleware to handle tokenization
  • Never sync raw card data between systems
  • Maintain audit logs of all data transfers

FAQ

Can I store customer payment methods in HubSpot for recurring billing?

You can store payment method tokens in HubSpot custom properties, but never store actual card numbers. These tokens are safe to store as they’re meaningless without your payment processor’s API credentials. Configure recurring billing logic using HubSpot workflows that trigger payment processing through serverless functions.

How do I handle refunds while maintaining PCI compliance?

Process refunds using the original transaction’s payment token or transaction ID. Create a HubSpot workflow that triggers a serverless function to call your payment processor’s refund API. Never collect card data again for refunds – always reference the original transaction.

What about HubSpot’s native payment features?

HubSpot Payments maintains its own PCI compliance and handles all card data securely. If using HubSpot Payments, you typically qualify for SAQ A as HubSpot handles the entire payment flow. Still implement proper access controls and monitor your account for suspicious activity.

How do I prove PCI compliance to my acquirer when using HubSpot?

Provide your completed SAQ (A or A-EP), your ASV scan results for your HubSpot-hosted domains, and documentation showing your payment integration architecture. Include screenshots of your iframe implementation and evidence that no card data enters HubSpot systems.

Can I use HubSpot forms to collect billing addresses for AVS verification?

Yes, collecting billing addresses in HubSpot forms is acceptable as this information isn’t considered sensitive cardholder data under PCI DSS. Configure your payment processor integration to use this address data for AVS checks while keeping the actual card number isolated in the payment iframe.

Conclusion

Achieving HubSpot PCI compliance requires careful implementation of payment integrations that keep cardholder data completely isolated from your CMS environment. By following the architectural patterns and security controls outlined in this guide, you can leverage HubSpot’s powerful e-commerce capabilities while maintaining a reduced PCI scope through SAQ A or SAQ A-EP.

Success depends on three critical factors: proper payment processor selection with hosted field capabilities, rigorous form validation to prevent accidental card data collection, and ongoing monitoring to ensure your configuration remains compliant as your site evolves.
