What is PCI DSS? Why is it important for businesses?

PCI DSS (Payment Card Industry Data Security Standard) is a set of security standards that businesses must comply with to protect customer data, prevent data theft, and build trust.

This standard is defined by the PCI Security Standards Council (PCI SSC), which was founded by Visa, MasterCard, American Express, Discover, and JCB.

PCI DSS helps businesses:

  • Build trust: Demonstrate a commitment to security and protecting customer data.

  • Comply with regulations: Helps businesses comply with data protection laws and regulations.

  • Maintain reputation: Avoid damage to reputation and brand image from data breaches.
