Key Steps to Ensure PCI DSS v4.0 Compliance

In our last blog, we explored the evolution of payment security and the importance of protecting your entire digital ecosystem. Today, we’re zooming in on the practical steps you need to take as a merchant to ensure you’re aligned with PCI DSS v4.0, the latest iteration of the payment security standard. Spoiler alert: it’s not just about checking boxes; it’s about future-proofing your business against evolving cyber threats.

How to Prepare for PCI DSS v4.0

1. Know Your SAQ Forms: 

   First things first—compliance starts with understanding which Self-Assessment Questionnaire (SAQ) applies to your payment setup. The form you fill out depends on how you process payments:

   • SAQ A-EP Form: For merchants who receive card data directly on their website and pass it to a third party through server-to-server integration.
   • SAQ-A Form: For merchants using a hosted or embedded checkout (like a redirect or iFrame).
     
     
2. Secure Your Web Environment:
   

   Running an eCommerce site means hackers are always knocking at your door. So, how do you keep them out? Start with the basics: 

   • Implement a web application firewall and follow secure coding practices.
   • Perform regular vulnerability scans and apply security patches to your website.
     
     
3. Keep Software Updated:
   

   You know that annoying little pop-up reminding you to update your software? Yeah, it’s not just a nuisance—it’s a lifeline. Ensure that your eCommerce platform and CMS are always up-to-date, and don’t neglect those plugins and themes. They’re often the weakest link in your security chain.

   • Ensure your ecommerce platform and content management system (CMS) are always up-to-date.
   • Keep all plugins and themes patched with the latest security updates.
     
     
4. Monitor for Vulnerabilities:
   

   The bad guys are getting smarter, which means you need to stay two steps ahead. Set up automated scanning tools to keep an eye out for vulnerabilities 24/7. It’s not enough to just check in periodically—you need to know about issues the moment they arise.

   • Use automated scanning tools to regularly check for weaknesses on your website.
   • Act quickly to patch any vulnerabilities that could expose sensitive payment data.
     
     
5. Review Your Third-Party Providers:
   

   Your payment security isn’t just about what’s happening on your website. If your third-party partners aren’t PCI DSS compliant, their vulnerabilities can become your vulnerabilities. Do your homework, and confirm that they’re meeting the standards, too.

   • Confirm that all your payment-related partners are also PCI DSS compliant. Any gaps in their security could impact yours.
