Who Are Affected by the PCI DSS 4.0 DMARC Mandate?

Cybercriminals deploy sophisticated methods to exploit vulnerabilities within your organization’s – not sparing email communications. Threat actors are adept at impersonating trusted brands and tricking victims into disclosing private financial information. By making DMARC compliance a mandate, the PCI SSC aims to reduce the risk of domain impersonation and phishing attacks.

The mandate doesn’t just affect businesses. It goes beyond that to impact all entities handling card payments. If your business or service falls into any of the following categories, you must comply with the mandate by March 31, 2025:

1. Organizations Handling Cardholder Data

Any business that processes, stores, or transmits cardholder data (CHD) or sensitive authentication data (SAD).

Examples: retailers, e-commerce platforms, and financial institutions.

2. Service Providers

Third-party service providers who are responsible for acquiring, processing, accepting, or issuing cardholder data on behalf of other organizations.

Examples: payment gateways, processors, and managed IT service providers.

3. Entities Storing or Transmitting Cardholder Data

Organizations that store, process, or transmit cardholder data, even if they do not directly handle payments.

Examples: cloud service providers and data centers.

4. System Components and Individuals

Any system components (e.g., servers, applications, or devices) or individuals directly or indirectly connected to systems that handle cardholder data.

Examples: IT administrators, developers, and security teams.

5. Indirectly Connected Systems

Entities with system components that are indirectly connected to systems handling cardholder data.

Examples: marketing platforms or customer support tools that interact with payment systems.

6. Small, Mid-Sized, and Enterprise-Level Businesses

The mandate applies to organizations of all sizes, from small businesses to large enterprises.

Compliance is not limited by the scale of operations but by the involvement in cardholder data handling.

Consequences of Non-Compliance with PCI DSS DMARC Requirements

Organizations, irrespective of size, must ensure compliance with PCI DSS 4.0 by configuring DMARC before the 31st of March 2025. Non-compliance may lead to several complications, including:

1. Financial penalties: the immediate repercussion for businesses failing to comply with the requirements is heavy financial penalties (ranging from $5000 – $100,000).
2. Risk of impersonation: the heightened risk of brand impersonation through domain spoofing attempts.
3. Loss of trust: Reputational damage as a result of excessive spam complaints.
4. Low email deliverability rates: Induced poor email deliverability due to lack of customer trust and poor domain reputation.

To avoid last-minute compliance issues, this is the cue for businesses to act fast and implement DMARC for their domains!
