The Evolution of PCI 3D Secure and What's Next?
PCI 3DS Compliance & Assessment Services
Secure authentication flows within the 3D Secure framework to protect card-not-present transactions and prevent fraud in digital payments. Implement strong authentication across the cardholder, merchant, and issuer domains, organizations to strengthen transaction security and meet PCI compliance requirements.
Why it matters
E-Commerce Security & Authentication Challenges
Rising CNP Fraud Risks:
Online card-not-present transactions remain highly vulnerable to fraud, requiring stronger authentication controls.
Managing Complex Authentication Flows:
3DS introduces additional verification layers that must operate seamlessly within the payment journey while maintaining strong customer authentication.
Three-Domain Security Complexity:
Securing authentication across the cardholder, merchant, and issuer domains introduces architectural and operational challenges.
Sensitive 3DS authentication data:
3DS authentication flows involve the transmission of sensitive data that must be securely handled and protected.
Defining Scope and Roles Across the Ecosystem:
Organizations must clearly identify which systems, components, and stakeholders fall within the PCI 3DS scope across the authentication infrastructure.

FAQs
The PCI 3DS (Three-Domain Secure) Standard defines physical and logical security requirements to protect the environments where 3DS components are hosted. It secures card-not-present (CNP) transactions by providing an additional layer of authentication.
The standard protects three specific domains: the Issuer Domain (the bank issuing the card), the Acquirer Domain (the merchant's bank), and the Interoperability Domain (the payment systems that connect them).
Any third-party service provider that manages or hosts 3DS components—specifically Access Control Servers (ACS), Directory Servers (DS), or 3DS Servers (3DSS)—on behalf of merchants or issuing banks must validate their compliance.
PCI DSS secures the general storage and transmission of cardholder data, while PCI 3DS specifically secures the infrastructure and cryptographic keys used for real-time identity authentication during digital (card-not-present) checkout flows.
No, PCI 3DS is a complementary standard. While PCI 3DS secures the authentication process, the entity must still comply with PCI DSS if they capture, store, or transmit primary account numbers (PAN) during the transaction.
Service providers hosting 3DS components must undergo an official assessment annually by a recognized 3DS Assessor to ensure continuous protection against emerging e-commerce fraud vectors.
The audit evaluates network security controls, system hardening, logical access management, and the cryptographic procedures used to protect 3DS authentication data and cryptographic keys within the designated 3DS environment.
SISA acts as an approved 3DS Assessor to evaluate your Access Control Servers, Directory Servers, and 3DS Server environments. We help service providers validate their security controls to ensure frictionless and secure digital authentication.
PCI 3DS compliance is essential for the e-commerce and financial technology (FinTech) industries. It specifically targets third-party service providers, payment gateways, and acquiring banks that host Access Control Servers (ACS) or Directory Servers to authenticate card-not-present digital transactions.
