PCI DSS (Payment Card Industry Data Security Standard) is not a federal or state law — it’s a private standard developed by major card brands (Visa, Mastercard, American Express, Discover, JCB) and managed through the PCI Security Standards Council.
Compliance isn’t legally mandated by government agencies; however, card networks and acquiring banks enforce it contractually.
Noncompliance can result in fines, higher transaction fees, or loss of card-processing privileges.
If there’s a data breach, you still face legal risks — such as civil suits or regulatory scrutiny under laws like CCPA, GDPR, or HIPAA.
PCI DSS applies broadly — regardless of company size or transaction volume — including:
Merchants (any business accepting card payments)
Service providers, acquirers, issuers, and processors
Even if you don’t store cardholder data, but only process or transmit it, compliance still applies
PCI DSS organizes its standards into six control objectives, divided into 12 core requirements. Key highlights include:
Install and maintain network security controls (e.g., firewalls)
Apply secure configurations to systems and remove default passwords
Protect stored cardholder data (limit, encrypt, mask)
Encrypt transmission of cardholder data across public networks
Deploy and update antimalware protections
Develop and maintain secure systems and applications
Restrict access to cardholder data based on business need
Identify users and authenticate access (e.g., MFA)
Restrict physical access to cardholder data
Log and monitor access to systems and data
Test security systems and processes regularly
Maintain organizational information security policies
