Everything merchants, fintechs, and service providers need to master the Payment Card Industry Data Security Standard — from the 12 requirements and merchant levels to SAQs, RoCs, and PCI DSS v4.0. Practical playbooks, checklists, and real assessor insight, organized by where you are in the journey.
PCI DSS (Payment Card Industry Data Security Standard) is the global security standard, maintained by the PCI Security Standards Council, that every organization which stores, processes, or transmits payment card data must follow. It defines 12 core requirements — from network security and encryption to access control and monitoring — designed to protect cardholder data. How you prove compliance depends on your merchant level: smaller businesses complete a Self-Assessment Questionnaire (SAQ), while the largest undergo a formal Report on Compliance (RoC) by a Qualified Security Assessor. This hub brings together everything you need to understand, achieve, and maintain PCI DSS compliance and earn your pci dss certification.

The twelve PCI DSS requirements are organized under six control objectives. Hover or tap a panel to expand it — swipe on mobile.
Install network security controls (firewalls) and apply secure configurations, replacing all vendor-supplied defaults across every system component.
Deep dive →Render stored cardholder data unreadable through encryption, truncation, or tokenization, and protect it with strong cryptography whenever it crosses open, public networks.
Deep dive →Protect all systems against malware and develop and maintain secure systems and software through patching, secure development, and change control.
Deep dive →Restrict access to cardholder data by business need-to-know, uniquely identify and authenticate every user, and restrict physical access to data.
Deep dive →Log and monitor all access to systems and cardholder data, and test the security of systems and networks regularly with scans and penetration tests.
Deep dive →Maintain a policy and program that supports information security for all personnel, keeping the whole compliance effort governed and accountable.
Deep dive →Your transaction volume sets your level — and your level decides whether you self-assess or face a formal audit. Thresholds vary slightly by card brand.
