Summary

If your organization develops or customizes marketing software, secure development practices are mandatory. This includes web applications that collect customer data for marketing purposes. Marketing teams often have broader data access than necessary. PCI DSS requires a least-privilege model. Audit logs are essential for detecting breaches and demonstrating compliance. Marketing platforms must log all access to systems in scope.

PCI DSS Requirements List for Marketing Software: What You Need to Know

Marketing software handles customer data every day — email addresses, purchase histories, behavioral profiles, and sometimes payment card information. If your marketing platform touches cardholder data in any way, PCI DSS compliance isn’t optional. This guide breaks down the specific PCI DSS requirements that apply to marketing software, explains what “in scope” really means, and gives you a practical checklist to work from.

What Is PCI DSS and Why Does It Apply to Marketing Software?

The Payment Card Industry Data Security Standard (PCI DSS) is a set of security controls established by the major card brands (Visa, Mastercard, American Express, Discover, and JCB) through the PCI Security Standards Council. Version 4.0, released in 2022, is now the active standard.

Marketing software becomes subject to PCI DSS when it:

Stores, processes, or transmits cardholder data (CHD) or sensitive authentication data (SAD)
Connects to systems that handle payment data (e.g., CRM integrations with e-commerce platforms)
Receives data feeds that include card numbers, expiration dates, or CVV codes
Hosts landing pages or forms that collect payment information

Even if your marketing tool only receives tokenized or masked card data, you may still fall within scope depending on how your environment is architected.

The 12 PCI DSS Requirements: How They Apply to Marketing Software

PCI DSS v4.0 organizes its controls into 12 core requirements grouped under six goals. Here’s how each requirement maps to a typical marketing software environment.

Requirement 1: Install and Maintain Network Security Controls

Marketing platforms must ensure that firewalls and network segmentation properly isolate any systems that touch cardholder data. If your marketing server sits on the same network segment as your payment processor, your entire marketing environment becomes in scope.

Key actions:

Segment marketing systems from payment-processing systems
Document network diagrams showing data flows
Review firewall rules at least every six months

Requirement 2: Apply Secure Configurations to All System Components

Default passwords and unnecessary services are a major attack vector. Marketing software — including third-party plugins, analytics tools, and email platforms — must be hardened before deployment.

Key actions:

Change all vendor-supplied default credentials
Disable or remove unnecessary features, ports, and protocols
Maintain a system configuration inventory

Requirement 3: Protect Stored Account Data

This is one of the most critical requirements for marketing teams. If your CRM or marketing automation platform stores any primary account numbers (PANs), they must be protected using strong encryption (AES-256 or equivalent).

Key actions:

Audit your marketing database for stored PANs — most marketing tools should not store them at all
Implement data retention and deletion policies
Mask PANs when displayed (show only the last four digits)
Never store CVV/CVC codes, PINs, or full magnetic stripe data

Requirement 4: Protect Cardholder Data with Strong Cryptography During Transmission

Any cardholder data transmitted over open, public networks must be encrypted. This applies to API calls between your marketing platform and other systems, as well as email communications containing sensitive data.

Key actions:

Enforce TLS 1.2 or higher for all data transmissions
Disable SSL and early TLS versions
Use strong cryptography for all API integrations

Requirement 5: Protect All Systems and Networks from Malicious Software

Marketing platforms are frequent targets for malware because they often have broad access to customer data and integrate with many third-party tools.

Key actions:

Deploy anti-malware solutions on all applicable systems
Keep anti-malware definitions current
Perform periodic scans and log results

Requirement 6: Develop and Maintain Secure Systems and Software

If your organization develops or customizes marketing software, secure development practices are mandatory. This includes web applications that collect customer data for marketing purposes.

Key actions:

Follow a secure software development lifecycle (SDLC)
Conduct code reviews and vulnerability testing
Apply security patches within defined timeframes (critical patches within one month)
Protect web-facing applications with a Web Application Firewall (WAF)

Requirement 7: Restrict Access to System Components and Cardholder Data by Business Need to Know

Marketing teams often have broader data access than necessary. PCI DSS requires a least-privilege model.

Key actions:

Define roles with the minimum data access required
Review and update access rights at least every six months
Restrict access to cardholder data to only those who need it for their job function

Requirement 8: Identify Users and Authenticate Access to System Components

Every user accessing marketing systems that touch cardholder data must have a unique ID. Shared accounts are not permitted.

Key actions:

Assign unique user IDs to all marketing platform users
Enforce multi-factor authentication (MFA) for all access into the cardholder data environment
Set strong password policies (minimum 12 characters under PCI DSS v4.0)
Disable inactive accounts within 90 days

Requirement 9: Restrict Physical Access to Cardholder Data

If your marketing team works with on-premises servers or physical media containing cardholder data, physical security controls apply.

Key actions:

Control physical access to data centers and server rooms
Implement visitor logs and badge access
Securely destroy physical media containing cardholder data

Requirement 10: Log and Monitor All Access to System Components and Cardholder Data

Audit logs are essential for detecting breaches and demonstrating compliance. Marketing platforms must log all access to systems in scope.

Key actions:

Enable logging on all in-scope marketing systems
Retain logs for at least 12 months (three months immediately available)
Review logs daily for anomalies
Implement a Security Information and Event Management (SIEM) solution where appropriate

Requirement 11: Test Security of Systems and Networks Regularly

Regular testing ensures that your security controls are actually working. This includes vulnerability scans and penetration testing.

Key actions:

Conduct internal and external vulnerability scans quarterly
Perform penetration testing at least annually and after significant changes
Use Approved Scanning Vendors (ASVs) for external scans
Monitor for unauthorized wireless access points

Requirement 12: Support Information Security with Organizational Policies and Programs

PCI DSS requires a formal information security policy and a risk management program. Marketing teams must be included in security awareness training.

Key actions:

Maintain a written information security policy reviewed annually
Conduct security awareness training for all personnel with access to cardholder data
Maintain an incident response plan
Manage third-party service provider relationships with documented agreements

Scoping Your Marketing Software for PCI DSS

One of the most important steps is determining whether your marketing software is actually in scope. Work through these questions:

Does the software store, process, or transmit PANs? If yes, it’s in scope.
Is it connected to systems that do? If yes, it may be in scope.
Does it receive data that could be used to reconstruct a PAN? If yes, consult a Qualified Security Assessor (QSA).

The best practice for marketing software is to eliminate cardholder data from your marketing environment entirely. Use tokenization, pseudonymization, and data minimization to reduce scope and compliance burden.

Third-Party Marketing Vendors and PCI DSS

Most marketing teams rely on third-party SaaS tools — email service providers, analytics platforms, advertising networks, and CRM systems. Each vendor that touches your cardholder data environment must also be PCI DSS compliant.

What to do:

Request a current Attestation of Compliance (AOC) from each vendor
Include PCI DSS obligations in vendor contracts
Maintain a list of all third-party service providers and their compliance status
Review vendor compliance annually

Frequently Asked Questions

Does my email marketing platform need to be PCI DSS compliant?

It depends on what data flows through it. If your email platform only handles email addresses and campaign metrics, it likely falls outside PCI DSS scope. However, if it receives data feeds containing cardholder information or connects to in-scope systems, it must meet PCI DSS requirements. Always map your data flows before making this determination.

What happens if my marketing software has a data breach involving cardholder data?

A breach can result in significant fines from card brands, mandatory forensic investigations, increased transaction fees, and potential loss of the ability to process card payments. Non-compliance discovered during a breach investigation typically results in much higher penalties.

Is PCI DSS v4.0 different from v3.2.1 for marketing software?

Yes. PCI DSS v4.0 introduces stronger authentication requirements (12-character passwords, MFA for all CDE access), new requirements for phishing-resistant MFA, and a greater emphasis on targeted risk analysis. Marketing teams should review the delta document published by the PCI SSC and update their compliance programs accordingly.

Can I use a SaaS marketing platform and still be PCI compliant?

Yes, but you must verify that the SaaS provider is PCI DSS compliant and understand the shared responsibility model. The provider’s compliance does not automatically make your use of the platform compliant — you are still responsible for how you configure, access, and use the tool.

How often do I need to reassess my marketing software for PCI DSS compliance?

PCI DSS requires annual validation for most merchants and service providers, plus reassessment after significant changes to your environment. Any new marketing tool integration, data flow change, or system upgrade should trigger a scoping review.
