Validate your Cisco Meraki network segmentation, firewall rules, and access controls against PCI-DSS v4.0. Protect cardholder data with confidence.
Start Free TodayThe Payment Card Industry Data Security Standard (PCI-DSS) is a global security standard for any organisation that stores, processes, or transmits credit card data. Version 4.0, released in March 2022 with mandatory compliance from March 2025, represents the most significant update in over a decade.
PCI-DSS v4.0 introduces a customised approach alongside the traditional defined approach, giving organisations more flexibility in how they meet security objectives. However, the network requirements are non-negotiable: proper segmentation of the cardholder data environment (CDE), strict firewall rules, encrypted wireless, and robust access controls.
For Meraki networks, many PCI-DSS requirements map directly to dashboard configurations that MerakiGuard can audit automatically — from VLAN segmentation and L3/L7 firewall rules to admin access controls and change detection.
Every scan analyses your live Meraki configuration against PCI-DSS v4.0 network security requirements. Here is what we validate.
Validates that your cardholder data environment is properly segmented from other network zones using VLANs and inter-VLAN firewall rules. Weak segmentation is the most common PCI failure.
Req. 1Analyses MX L3 and L7 firewall rules for overly permissive entries, missing deny-all defaults, and rules that allow traffic into or out of the CDE without business justification.
Req. 1Checks that all SSIDs in scope use strong encryption (WPA2/WPA3-Enterprise recommended). Detects open networks, PSK weakness, and SSIDs broadcasting in the CDE zone.
Req. 4Verifies role-based access for Meraki Dashboard administrators, checks for MFA enforcement, and flags accounts with excessive privileges or shared credentials.
Req. 7 & 8Monitors for configuration drift between scans. PCI-DSS requires change detection mechanisms for critical system files, configurations, and content. MerakiGuard tracks every change.
Req. 10 & 11Checks that Meraki MX intrusion detection and prevention is enabled and properly configured at network boundaries, as required for monitoring traffic in and out of the CDE.
Req. 11If your organisation touches card payment data in any way, PCI-DSS applies. The scope is broader than many IT teams realise.
Any business with point-of-sale terminals, card readers, or online payment forms. Even if you outsource processing, your network is in scope if card data traverses it.
Hotels, restaurants, and venues processing card payments. Guest Wi-Fi networks on the same Meraki infrastructure must be properly segmented from POS systems.
MSPs, payment processors, and any organisation that stores, processes, or transmits cardholder data on behalf of other businesses. Higher compliance burden applies.
PCI-DSS non-compliance carries some of the most severe financial and operational consequences of any security standard.
Card brands can levy fines of $5,000 to $100,000 per month on acquiring banks for PCI non-compliance, which are passed through to the merchant. Fines escalate the longer non-compliance persists.
Repeated non-compliance or a breach can result in your merchant account being terminated. Losing the ability to accept card payments is an existential threat to most businesses.
If a breach occurs while non-compliant, you face forensic investigation costs, card replacement fees, fraud losses, and potential lawsuits. Average breach cost exceeds $4 million.
A publicly disclosed card data breach erodes customer trust instantly. Customers abandon businesses that cannot protect their payment information.
