PCI compliance network help for coastal restaurants and shops
Separate networks keep card terminals, guest Wi-Fi and staff systems apart over your existing cabling, for businesses from Charleston to Savannah.
Network segmentation basics
Keeping payments apart from free guest access
PCI Security Standards Council guidance states businesses offering free Wi-Fi need a separate network for processing payments. CloudCentric installs these controls for your restaurant or boutique.
- 1
Card terminals apart
Card terminals sit on their own network, entirely separated from staff laptops and guest internet over the exact same cabling.
- 2
Guest internet access
Guest Wi-Fi reaches internet connections only, isolated from card readers and cameras.

Network traffic logs
Access rules govern traffic between zones, recording a searchable log of blocked connections ready for review.
Networks built for your daily operations
Separation rules protect devices sharing one internet connection. Operations keep running securely across your spaces.
Network traffic zones
One connection split into distinct zones
Custom configurations group your devices into secure zones behind a single gateway. Firewalls apply specific access rules between each isolated group.

Traffic logs and access rules
Visual grids show every pair of zones and whether traffic between them is allowed or blocked. Dedicated logs display blocked connections alongside rule names.
Visual rows and columns map out where traffic starts and ends, showing allowed connections and blocked access between all configured zones.
Dedicated logs list specific traffic blocked by your firewalls. Searchable records display stopped traffic alongside the exact name of the responsible rule.

Understanding compliance and network roles
Building separate networks represents just one part of PCI DSS compliance. Knowing your duties helps keep operations running smoothly during assessments.
CloudCentric designs your physical connections and firewalls, managing hardware separation across your locations in the Lowcountry.
Network separation
Engineers build separate networks for card terminals, staff devices, and guest access sharing the exact same cabling infrastructure.
Access rules and logs
Hardware configurations block unwanted connections silently. Searchable logs record blocked traffic for administrative review and evidence gathering.
Second internet line
Backup connections keep card terminals online and processing transactions if your primary internet service ever goes down.
Network answers
CloudCentric gathers necessary network evidence and firewall answers to help you complete your required self-assessment questionnaire.
External organizations determine compliance requirements and enforcement. Specific validation rules come directly from your financial partners.
Acquiring bank
Acquiring banks and payment brands maintain compliance validation programs and determine your reporting requirements. Financial partners decide who must validate and how.
PCI Security Standards Council
PCI SSC publishes PCI DSS, currently v4.0.1, and does not enforce compliance or define validation reporting requirements for your business.
Qualified assessor
Specialized assessors evaluate and report on network controls only where one is formally required.
Adding network controls to your business
Systematic upgrades replace single flat networks with isolated segments. New gateways run access rules securely protecting your devices.
- 1
Survey connections and devices
Engineers evaluate your incoming internet service, recording termination points and listing all hardware.
- 2
Decide what stays apart
Discussions finalize which systems remain separate before ordering any new gateway equipment.
- 3
Put networks in place
Technicians install firewalls and program access rules, leaving existing cabling and access points alone unless upgrading them.
- 4
Test from guest side
Handover includes checks verifying visitor phones cannot access your card terminals or cameras from the guest side.
- 5
Keep evidence ready
Documentation records how each network control operates, remaining available for partner questionnaires or audits.
Questions about network segmentation
- Does CloudCentric make my business PCI compliant?
CloudCentric sets up required network controls, such as separate networks and firewalls, and helps gather evidence for your self-assessment. Your acquiring bank or payment brand ultimately decides your compliance validation requirements.
- Who decides what small businesses must file?
Payment brands and acquiring banks maintain compliance validation programs, deciding who must validate and how. PCI Security Standards Council simply publishes the data security standard.
- Does free guest Wi-Fi need a separate network?
PCI SSC states that brick-and-mortar businesses offering free customer Wi-Fi need to use a separate network for processing payments. Network segmentation keeps these visitor connections safely isolated.
- What does network segmentation mean?
Network segmentation groups devices into isolated zones. Firewalls allow card terminals to operate on private networks completely disconnected from patron Wi-Fi, even while sharing the exact same internet line.
- Can card terminals stay online if internet fails?
Cellular backup units using 5G and LTE networks maintain active connections. Redundant lines keep registers and phones operating when your primary internet service goes down.
- Where does CloudCentric install these networks?
Service covers businesses across Charleston and the Lowcountry. Engineers support Mount Pleasant, North Charleston, Isle of Palms, Folly Beach, Kiawah, Beaufort, Bluffton, Hilton Head, and Savannah.
