Quick Answer

PCI DSS v4.0, released March 31, 2022, requires DMARC implementation by 2025 for any entity that stores, processes, or transmits cardholder data. The standard shifts from prescriptive rules to a customized approach: continuous risk assessment, prioritized authentication, ongoing monitoring, and accountability for every stakeholder in the payment ecosystem. DMARC fits because the goal is fraud prevention. By verifying that only authorized senders can use a domain, DMARC reduces phishing on transaction emails, protects deliverability of payment alerts and confirmations, and aligns with the Google and Yahoo bulk-sender requirements introduced in 2024\. Non-compliance carries financial penalties, reputational damage, and lost customer trust as payment fraud heads toward $40.63 billion by 2027.

Is the [card payment system](https://sea.mastercard.com/en-region-sea/business/merchants/start-accepting/payment-process.html) of your business **secure enough** to keep cyber predators at bay? Not as much as you think! 

There’s no doubt that online transactions have made doing business a lot easier than it ever was, but with **opportunity comes a cost**. A cost that you have to pay, especially if you are not wary of the [ever-evolving cyber-threat landscape](https://www.financialexpress.com/business/digital-transformation-cybersecurity-predictions-for-2024-navigating-the-evolving-threat-landscape-3356635/). 

_The truth is, the situation is only getting worse with grave cyberattacks like phishing and spoofing lurking over your unsuspecting customers who trust their sensitive information, like **card details**, with your payment systems_. To [protect vulnerable users](/email-security/data-privacy-and-protection-11-ways-to-protect-user-data/) and maintain the integrity of your transaction processes, the [Payment Card Industry Data Security Standard (PCI DSS)](https://en.wikipedia.org/wiki/Payment%5FCard%5FIndustry%5FData%5FSecurity%5FStandard) **version 4.0 is a major update** you should know about! Out of all the updates, the one that stands out is the mandatory implementation of **DMARC by 2025**. 

Let’s learn more about it in this article.

## Decoding PCI DSS v4.0

The [payment card industry](https://www.hindustantimes.com/brand-stories/credit-card-industry-trends-in-2024-insights-customer-preferences-101711106248548.html) has never been secure enough, especially not until 2004 when all the big companies like [Visa](https://usa.visa.com/), [Mastercard](https://www.mastercard.us/en-us.html), [American Express](https://www.americanexpress.com/us/), etc., unanimously came up with the Payment Card Industry Data Security Standard (PCI DSS), designed to **ensure safe and secure** card transactions. After multiple iterations, the fourth edition of these standards, PCI DSS v4.0 was released on March 31, 2022\. 

The latest version of PCI DSS talks about the following updates:

### A Customized Approach to Security

The PCI DSS v4.0 reveals that **innovation and security** can go hand in hand. With this outlook, it offers organizations that rely on [payment systems](https://testbook.com/banking-awareness/types-of-card-payment) to implement solutions that fit their specific needs instead of prescribing them a strict rulebook to meet security standards. 

### Making Authentication a Priority

The latest update to PCI DSS emphasizes the importance of [data protection](/email-security/9-best-practices-to-manage-sensitive-data-carefully/) by prioritizing robust authentication methods. This means that your clients’ sensitive information, like their credit card details, will be secure during transactions and when stored. This update aims to make sure that **only authorized users** can access your information, which reduces the risk of [data breaches](https://www.bbc.com/news/uk-68966497) and fraud.

### Emphasis on Continuous Security

The PCI DSS v4.0 recognizes that [cybersecurity](/) is no longer about dodging attacks but about building a **cyber-resilient ecosystem**, which is certainly not a one-and-done endeavor. _With this update, the organizations will be compelled to prioritize continuous monitoring and regular updates._ 

### Regular Reporting and Accountability

The fourth version of the security standards aims to make **governance and accountability** a priority, especially when it comes to handling [sensitive customer information](https://bigid.com/blog/sensitive-information-guide/). By holding the stakeholders accountable, [compliance management](https://sprinto.com/blog/compliance-management/) is no longer left to chance but is seen as an important task with well-defined processes. 

### Continuous Risk Assessment and Management

PCI DSS v4.0 stresses following a more dynamic approach that is **risk-based** instead of static. The thing with a [risk-based approach](https://www.mckinsey.com/capabilities/risk-and-resilience/our-insights/the-risk-based-approach-to-cybersecurity) is that it requires you to continuously assess, evaluate, and fine-tune your security practices instead of following a pre-defined template. 

## Identifying the Target Audience of PCI DSS v4.0

Since [cyber attackers](https://www.bbc.com/news/articles/cglvpnpxx87o) are **not too picky** about their targets, it only makes sense that the security standards laid out to challenge these attackers should not be limited to a particular sector or group of organizations. _That being said, it is recommended that **all organizations**, including merchants, processors, acquirers, issuers, and service providers, **should follow the new set of rules**_. 

[![PCI-DSS Certification](https://media.mailhop.org/duocircle/images/2024/05/DMARC-generator-3.jpg)](https://media.mailhop.org/duocircle/images/2024/05/DMARC-generator-3.jpg)

The [other entities that are a part of the payment ecosystem](https://directpaynet.com/payment-ecosystem-explained/) and should comply with PCI DSS v4.0 include:

- Any entity, be it a company, individual, or a system component that is somehow involved in storing, processing, or transmitting cardholder data, is **required to adhere** to PCI DSS v4.0
- Businesses, people, or processes that might indirectly impact the security of the [Cardholder Data Environment (CDE)](https://www.techtarget.com/searchsecurity/definition/cardholder-data-environment-CDE) should follow the guidelines
- Even if a system component does not directly handle [cardholder data (CHD)](https://sycurio.com/knowledge/glossaries/card-holder-data-chd-pci-dss) or [sensitive authentication data (SAD)](https://www.eckoh.com/glossary/sad) but is connected to systems that do manage CHD or SAD, they **ought to comply**.

## The Role and Relevance of DMARC in PCI DSS Compliance

As we have already mentioned, [DMARC](/email/dmarc) implementation is one of the **most important updates** of the latest PCI DSS v4.0 standards. The reason the Payment Card Industry Security Standards Council places so much stress on this authentication protocol is that the basic premise of the PCI DSS v4.0 is [fraud prevention](/email-security/7-best-ways-to-prevent-fraud-before-its-too-late/) and [email security](/content/email-security-services), and **DMARC directly aligns with these goals**.

Take a look at how!

### Enhanced Security Against Phishing Attacks

[![phishing attacks](https://media.mailhop.org/duocircle/images/2024/05/hosted-email-server-6482.jpg)](https://media.mailhop.org/duocircle/images/2024/05/hosted-email-server-6482.jpg)

By ensuring that only those authorized to send emails on your behalf can do so, DMARC can significantly **bring down the risk** of [phishing attacks](https://cybersecuritynews.com/fbi-warns-of-phishing-attack/). This is especially important when sending [transaction-related emails](https://www.getvero.com/resources/guides/lifecycle-marketing/transactional-emails/) because once imposters get in, they are sure to execute nefarious activities in the disguise of your organization. 

### Improved Email Deliverability

_Apart from protecting your systems against phishing attacks, DMARC also ensures that your emails land in the **recipient’s inbox**, especially if they are important emails like payment alerts or transaction confirmations._

### Seamless Regulatory Compliance

Last year, the key players in the email industry, [Google and Yahoo](/email-services/google-yahoo-mandatory-to-deploy-dmarc-for-more-than-5000-daily-emails/) set new standards in the cybersecurity realm. Following the same suit, PCI SSC has now taken a similar approach by mandating DMARC deployment by 2025\. This means that you can no longer be complacent about your email security measures, or else it will cost you significantly in terms of potential [financial penalties](https://thoropass.com/blog/compliance/pci-dss-fines-and-penalties/), **business reputation**, and [customer trust](https://www.bolddesk.com/blogs/customer-trust). 

### Less Risk of Financial Loss

Implementing DMARC to comply with PCI DSS v4.0 also means mitigating financial risks associated with data breaches, regulatory fines, legal liabilities, and [reputational damage](https://en.wikipedia.org/wiki/Reputational%5Fdamage). Not to mention, it will also contribute to **long-term financial stability** by fostering a [secure business environment](https://www.brandignity.com/2022/08/maintaining-a-secure-business-environment-in-the-digital-age/). 

With [payment frauds](https://www.thenationalnews.com/business/money/2024/05/09/uae-bank-fraud-criminals-increasingly-focusing-on-contactless-transactions/) expected to reach [$40.63 billion by 2027](https://eftsure.com/statistics/payment-fraud-statistics/), keeping up with the industry trends is more than just a recommendation; it’s an imperative.
