PCI DSS Compliance for Boston & Massachusetts Businesses
If your business accepts credit cards, PCI DSS compliance isn't optional. From restaurants and retail shops on the South Shore to multi-location businesses in Boston and on Cape Cod, Power Up Boston segments the payment network, hardens and patches the systems that touch card data, and helps you complete the Self-Assessment Questionnaire your processor asks for each year, without disrupting operations.

How We Help
From Segmentation to Your SAQ
Your point-of-sale network is the most common target for card data theft. We implement the technical controls PCI DSS asks for and help you document them for your payment processor.
Segment the Payment Network
Separate VLANs for POS terminals, the back office and guest Wi-Fi, so a guest device can never reach your payment systems.
Harden and Encrypt
Firewall configuration, encryption of card data in transit, vendor default passwords changed and unique IDs for every user.
Patch, Scan, Monitor
Security patching, vulnerability scanning and monitoring of the systems that touch cardholder data.
Complete the SAQ
We help you complete the annual Self-Assessment Questionnaire your processor requires and keep the evidence current.
Small Business
PCI Compliance for Restaurants, Retail and Small Businesses on the South Shore
Most of the PCI work we do is for owner-operated businesses with a point-of-sale system, a handful of workstations, and guest Wi-Fi, not for payment processors. For a restaurant that means the POS terminals, the kitchen display, and the back-office PC live on their own VLAN; the guest network is isolated so a diner's phone can never reach a terminal; the firewall only passes the traffic the processor needs; and the handheld pay-at-table devices are inventoried and patched. For a retail shop it is the same pattern applied to registers, the inventory PC, and the camera and music systems that share the network.
Then we help with the paperwork. Your processor wants a Self-Assessment Questionnaire each year, and the right one depends on how you take cards. We walk through how cards actually flow through the business, pick the SAQ that fits, set the network up so the shorter questionnaire applies wherever possible, and keep the evidence (network diagram, device list, scan results, policy) in a file you can hand over when asked. See our IT for restaurants and hospitality and IT for retail businesses pages for the rest of what those businesses run on.
Boston-area businesses usually come to PCI through a larger partner's vendor questionnaire or a cyber-insurance renewal that asks the same questions; the controls are identical and we document them once for both.

Massachusetts
PCI DSS and 201 CMR 17.00
PCI DSS is enforced by the card brands through your payment processor. Massachusetts adds a state obligation on top of it: under 201 CMR 17.00, a credit or debit card number tied to a resident's name is “personal information,” so any merchant holding that data must also maintain a Written Information Security Program (WISP).
The controls overlap: the 17.04 computer-system requirements (secure authentication, access control, encryption across public networks and wireless, monitoring, firewalls and patching, malware protection, employee training) cover most of the 12 PCI requirements above. We build them once and document them for both.
- Massachusetts WISP (201 CMR 17.00): the state baseline nearly every employer needs.
- HIPAA: for medical and dental practices that also take card payments at the front desk.
- CMMC: for defense contractors; the Level 1 safeguards cover the same access, authentication and patching controls.

FAQ
PCI DSS Compliance FAQ
What is PCI DSS?
The Payment Card Industry Data Security Standard (PCI DSS) is a set of security requirements for any business that accepts, processes, stores, or transmits credit card information. It's mandated by the major card brands (Visa, Mastercard, Amex, Discover) and enforced through your payment processor.
Does my small business need to be PCI compliant?
Yes. If you accept credit card payments in any form, in person, online, or over the phone, you must comply with PCI DSS. The level of compliance required depends on your transaction volume, but even the smallest merchant must complete a Self-Assessment Questionnaire (SAQ) annually.
What are the PCI DSS requirements?
PCI DSS has 12 core requirements organized into 6 goals: build a secure network, protect cardholder data, maintain a vulnerability management program, implement strong access control, regularly monitor and test networks, and maintain an information security policy.
Which SAQ does a small restaurant need?
It depends on how you take cards. A restaurant that only uses standalone terminals or a validated point-to-point-encrypted (P2PE) terminal on its own network fills out a much shorter questionnaire than one whose POS stores or transmits card data over the business network, and online ordering or phone orders can change the answer again. We review how cards actually flow through your restaurant, help you pick the SAQ your processor will accept, and set up the network so the shorter one applies wherever possible.
What happens if I'm not PCI compliant?
PCI DSS is enforced by the card brands through your payment processor rather than by a government agency. Non-compliance typically shows up as monthly fees on your processing statement, and after a breach the merchant is generally responsible for the forensic investigation, card reissuance, and fraud losses, and may lose the ability to accept cards at all. Massachusetts adds breach notification duties under M.G.L. c. 93H on top of that. Keeping the payment network segmented and the SAQ current is far cheaper than any of it.
How does Power Up Boston help with PCI compliance?
We implement the technical controls required for PCI compliance: network segmentation, firewall configuration, encryption, access controls, vulnerability scanning, and security patching. We also help you complete your SAQ and maintain ongoing compliance under managed IT, for businesses across Massachusetts from Boston and the South Shore to Cape Cod.
Do I need PCI compliance for my POS system?
Absolutely. Your point-of-sale system is the most common target for card data theft. We ensure your POS network is segmented, encrypted, patched, and monitored. We work with restaurants, retail shops, and service businesses across the South Shore and Greater Boston.
