Why IT must evolve from ‘break-fix’ to business partner in the age of cloud and AI
July 18, 2025Here's a simplified breakdown of PCI-DSS to help you understand the essentials:
PCI-DSS (Payment Card Industry Data Security Standard) is a set of security requirements to ensure that all companies that process, store, or transmit credit card information maintain a secure environment.
What Is PCI-DSS?
- PCI-DSS is a global standard that protects cardholder data and reduces credit card fraud.
- Any business that handles credit card payments online or offline must comply with PCI-DSS.
What Does PCI-DSS Require?
PCI-DSS is built around 12 main requirements, grouped into six goals:
- Build and maintain a secure network (e.g. use firewalls)
- Protect cardholder data (e.g. encrypt stored data)
- Maintain a vulnerability management program (e.g. update software)
- Implement strong access control measures (e.g. restrict access)
- Monitor and test networks regularly (e.g. track access to data)
- Maintain an information security policy (e.g. train staff).
How Do You Become PCI Compliant?
- Determine Your PCI Level: Your level depends on how many card transactions you process annually. Most small businesses are level 4 (the lowest) but check your transaction volume to be sure.
- Scope Your Environment: Identify all systems, people, and processes that touch cardholder data. The smaller your 'cardholder data environment', the easier compliance will be.
- Fill Out the Right Self-Assessment Questionnaire (SAQ): There are different SAQs depending on how you process payments (e.g. online, in-person, or via terminal). Most small businesses need to answer a questionnaire about their security practices.
- Conduct Quarterly Vulnerability Scans: If your systems are connected to the internet, you'll need regular scans by an Approved Scanning Vendor (ASV).
- Submit Your Documents: Submit your completed SAQ Attestation of Compliance (AoC) and scan results to your payment processor or the PCI Council.
Tips To Make PCI-DSS Simpler
- Limit where card data is stored or processed: Use third-party payment processors (like Stripe or PayPal) so card data doesn't touch your systems, reducing your compliance burden.
- Segment your network: Isolate systems that handle card data from the rest of your network to shrink the scope of compliance.
- Restrict access: Only let necessary staff access cardholder data.
- Regularly train staff: Ensure everyone knows how to handle card data safely.
If you focus on minimising where and how you handle card data, PCI-DSS compliance becomes much less confusing and much easier to manage.
