In short

PCI DSS compliance in Seattle at a glance

Where software meets checkout, PCI DSS follows, and in Seattle that meeting happens constantly. The City's Office of Economic Development includes retail and e-commerce in its description of the technology sector, so retailers, marketplaces, subscription services and payment platforms are all part of the picture. PCI DSS sets security requirements for systems that store, process or transmit payment card data: network controls, access management, monitoring, testing and policy. It is validated through a questionnaire or an assessor's report, not certified in the ISO sense. Smart architecture can shrink scope considerably. Sterling helps Seattle teams define scope early and prepare evidence from its New York office, and the acquirer decides the validation route.

Local drivers

What drives PCI DSS in Seattle

Demand is buyer-led: PCI DSS is requested through customer, tender or supplier terms rather than by a Seattle authority or zone rule.

Requirements

What PCI DSS requires

Strip away the vocabulary and PCI DSS asks any business that stores, processes or transmits card data to comply in six areas.

You know where card data livesThe cardholder data environment is scoped, data flows are mapped and the environment is segmented where possible.

Networks are protectedNetwork security controls restrict traffic to and from systems that handle card data, and configurations are hardened.

Stored data is minimised and protectedOnly the card data you need is kept, sensitive authentication data is not retained after authorisation except under issuer rules, and the rest is protected.

Access is restricted and authenticatedAccess to card data is limited to people who need it, with unique IDs and multi-factor authentication where required.

Systems are logged and testedActivity is logged and reviewed, vulnerabilities are scanned and patched, and penetration testing is carried out.

Policies and people keep it runningSecurity policies, staff awareness, vendor management and incident response keep controls working between assessments.

PCI DSS in Seattle: questions clients ask

Does a Seattle online retailer using a hosted checkout need PCI DSS?

It still has duties, but scope can be narrow. If a hosted checkout keeps card data off the retailer's systems, a short self-assessment may be enough. If the retailer's own systems store, process or transmit card data, the requirements expand.

How do card brands decide the PCI DSS validation level?

Mostly by transaction volume and whether the business is a merchant or a service provider, with the acquiring bank or card brands setting requirements. Ask your acquirer or payment processor which validation applies before choosing between a questionnaire and an assessor's report.
