Any firm in that world that stores, processes or transmits card data meets PCI DSS, the payment industry's security standard. It asks for a defined cardholder-data environment, network and system security, access control, monitoring, testing and policy. Compliance is validated through the route your acquirer or card brand requires. Sterling's Tokyo office helps you reduce scope, close gaps and prepare evidence in Effivity.

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 Tokyo: questions clients ask

How does a Tokyo fintech start PCI DSS work?

Start by mapping where card data enters, moves and rests, then try to shrink that footprint, for instance by using a validated payment processor. Scope decides how much of the standard applies. After that, close gaps and gather evidence for the validation route your acquirer or card brand sets.

Does Sterling validate PCI DSS compliance in Tokyo?

No. Sterling prepares the organisation: scoping, gap analysis, policies, training and evidence. Validation is carried out by a qualified assessor or by self-assessment, depending on your acquirer and card volume. Confirm which route applies with your acquirer before you plan the work.
