Comprehensive Guide to the Four Levels of PCI Compliance

PCI compliance is a requirement for any business that accepts, processes, or stores credit card information. But what does PCI compliance actually entail? And how do you know which level of PCI compliance your business needs to achieve?

This comprehensive guide will walk you through the four levels of PCI compliance and help you determine which level is right for your business.


Level 1 PCI Compliance

If your business processes more than 6 million credit card transactions per year, then you will need to achieve Level 1 PCI compliance. To achieve this level of compliance, you will need to complete a comprehensive security audit and implement a number of security measures, including firewalls, intrusion detection systems, and data encryption.


Level 2 PCI Compliance

If your business processes between 1 and 6 million credit card transactions per year, then you will need to achieve Level 2 PCI compliance. To achieve this level of compliance, you will need to complete a self-assessment questionnaire (SAQ) and implement a number of security measures, including firewalls, intrusion detection systems, and data encryption.


Level 3 PCI Compliance

If your business processes fewer than 1 million credit card transactions per year, then you will need to achieve Level 3 PCI compliance. To achieve this level of compliance, you will need to complete a self-assessment questionnaire (SAQ) and implement a number of security measures, including the use of a firewall and an intrusion detection system.


Level 4 PCI Compliance

If your business processes no credit card transactions (i.e., you accept payments in cash or check), then you will need to achieve Level 4 PCI compliance. To achieve this level of compliance, you will need to implement controls over security vulnerabilities, such as malware and spam.


The level of PCI compliance that your business needs to achieve will depend on a number of factors, including the number of credit card transactions that your business processes each year. By understanding the four levels of PCI compliance, you can ensure that your business is taking the necessary steps to protect its customers' confidential information.
