Data security is paramount in today’s digital age, especially for businesses that handle sensitive customer information. One crucial aspect of data security is adhering to the Payment Card Industry Data Security Standard (PCI DSS). The PCI DSS provides a set of requirements to ensure the safe handling of credit card information. However, not all businesses are held to the same level of compliance.
The PCI DSS provides four distinct compliance levels, each with its own requirements. This article will explore the four PCI DSS compliance levels and the specific requirements that businesses must meet to achieve each level. Whether a small online retailer or a multinational corporation, understanding PCI DSS compliance is essential for protecting your customers and your business.

How many PCI levels are there?
There are four levels of PCI compliance that a business can fall into. The number of transactions a business processes annually determines these levels. Each level has different requirements and expectations for maintaining compliance.
Level 1 is the highest level and is reserved for businesses that process over 6 million transactions annually. These businesses have the most rigorous requirements and must undergo an annual onsite assessment by a qualified security assessor (QSA).
Level 2 is for businesses that process 1 to 6 million transactions annually. Like level 1, level 2 businesses must undergo an annual assessment, but it can be done remotely by a QSA.
Level 3 is for businesses that process 20,000 to 1 million e-commerce transactions annually. These businesses must complete an annual self-assessment questionnaire (SAQ) and may also be required to undergo a vulnerability scan.
Level 4 is for businesses that process fewer than 20,000 e-commerce transactions annually or up to 1 million offline transactions. Similar to level 3, level 4 businesses must complete an annual SAQ and may need to undergo a vulnerability scan.
It’s important for businesses to know which level they fall into in order to understand their compliance obligations and ensure they are taking the necessary steps to protect their customer’s payment card data.
What are the 4 PCI DSS compliance levels?
- PCI Level 1: Merchants that process over 6 million card transactions annually
PCI Level 1 is the highest level of compliance within the Payment Card Industry Data Security Standard (PCI DSS) framework. It is designated for merchants that process over 6 million card transactions annually. Achieving and maintaining PCI Level 1 compliance is crucial for these merchants as it ensures the highest level of security for cardholder data.
To achieve PCI Level 1 compliance, merchants must undergo a rigorous assessment and validation process conducted by a Qualified Security Assessor (QSA). This process includes a comprehensive audit of the merchant’s systems, processes, and controls to ensure they meet all of the PCI DSS requirements.
The requirements for PCI Level 1 compliance cover a wide range of areas, including network security, physical security, access controls, and data encryption. Merchants must have robust firewalls in place to protect their network from unauthorized access, and they must implement strong access controls to ensure that only authorized individuals have access to cardholder data.
In addition to these measures, merchants must also regularly monitor and test their systems to identify any vulnerabilities or weaknesses. This includes conducting regular vulnerability scans and penetration tests to identify and address any potential security risks.
Maintaining PCI Level 1 compliance is an ongoing process that requires merchants to continually assess their systems and implement any necessary updates or improvements. Regular audits and assessments are necessary to ensure that compliance is maintained and that any changes to the merchant’s systems or processes are properly evaluated and validated.
It is important to note that achieving PCI Level 1 compliance is not a one-time task. Merchants must remain vigilant and proactive in their efforts to protect cardholder data and comply with the PCI DSS requirements. Failure to comply with these requirements can have serious consequences, including fines, penalties, and reputational damage.
- PCI Level 2: Merchants that process 1 to 6 million transactions annually
Level 2 is for businesses that process 1 to 6 million transactions annually. Like level 1, level 2 businesses must undergo an annual assessment, but it can be done remotely by a QSA. This process will include a comprehensive audit of the merchant’s systems, processes, and controls to ensure they meet all of the PCI DSS requirements.
- PCI Level 3: Merchants that process 20,000 to 1 million transactions annually
Level 3 is for businesses that process 20,000 to 1 million e-commerce transactions annually. These businesses must complete an annual self-assessment questionnaire (SAQ) and may also be required to undergo a vulnerability scan.
- PCI Level 4: Merchants that process fewer than 20,000 transactions annually
Level 4 is for businesses that process fewer than 20,000 e-commerce transactions annually or up to 1 million offline transactions. Similar to level 3, level 4 businesses must complete an annual SAQ and may need to undergo a vulnerability scan.
PCI DSS Requirements and Control Objectives
The PCI DSS requirements are divided into six categories:
1. Build and Maintain a Secure Network: This requirement focuses on establishing and maintaining a secure network infrastructure. It includes the installation of firewalls, secure network configurations, and regular testing of security systems.
2. Protect Cardholder Data: This requirement emphasizes the need for proper protection of cardholder data. It involves data encryption in transit and at rest, restricting access to cardholder data, and implementing security measures such as secure coding practices.
3. Maintain a Vulnerability Management Program: This requirement focuses on proactively identifying and mitigating vulnerabilities. It involves regular scanning of networks and systems for vulnerabilities and the application of security patches and updates.
4. Implement Strong Access Control Measures: This requirement ensures that only authorized individuals can access cardholder data. It involves using unique user IDs, strong authentication methods, and restricting access based on job responsibilities.
5. Regularly Monitor and Test Networks: This requirement emphasizes the importance of continuously monitoring and testing security systems. It involves the implementation of intrusion detection systems, regular testing of security controls, and the establishment of proper log management processes.
6. Maintain an Information Security Policy: This requirement focuses on developing and implementing a comprehensive information security policy. It involves the establishment of security policies and procedures, as well as the enforcement of security awareness and training programs.
How to Achieve PCI DSS compliance
1. Determine your compliance level: PCI DSS compliance levels are determined by the number of credit card transactions a business processes annually. Level 1 applies to businesses that process over 6 million transactions annually, while Level 4 applies to businesses that process less than 20,000 transactions annually.
2. Understand the requirements: PCI DSS consists of 12 requirements, which encompass areas such as network security, access control, and encryption. Familiarize yourself with these requirements and ensure your business meets each one.
3. Scope the environment: Determine the scope of your cardholder data environment (CDE). This includes identifying all systems, networks, and processes that interact with cardholder data. You can focus your compliance efforts on the relevant areas by clearly defining the scope.
4. Conduct a risk assessment: Perform a thorough risk assessment to identify any vulnerabilities or potential threats to your cardholder data. This assessment will help you prioritize your efforts and implement appropriate security controls.
5. Implement security controls: Based on the results of your risk assessment, implement security controls to mitigate any identified risks. These controls may include implementing firewalls, antivirus software, encryption, and access controls.
6. Develop and maintain written policies: Establish written policies and procedures that detail how your business handles cardholder data and adheres to PCI DSS requirements. These policies should be communicated to all employees and regularly reviewed and updated.
7. Regularly monitor and test security controls: Continuously monitor and test your security controls to ensure their effectiveness. This includes conducting regular vulnerability scans, penetration testing, and internal audits.
8. Complete a Self-Assessment Questionnaire (SAQ) or undergo a third-party audit: Depending on your compliance level, you may be required to complete an SAQ or undergo a third-party audit to validate your compliance. The SAQ is a self-assessment tool provided by the PCI Security Standards Council, while a third-party audit involves an independent assessment by a qualified security assessor.
9. Submit compliance documentation: Once you have completed the necessary steps and achieved compliance, submit your compliance documentation to your acquiring bank or payment processor.
