Payment Cryptography (Payment HSM)

Secure payment transactions with high-assurance cryptographic controls

Payment systems operate in highly targeted and tightly regulated environments. Data Protection Services (DPS) delivers payment cryptography solutions that protect cardholder data, secure transactions, and enforce strict cryptographic controls across payment processing environments.We help organisations reduce fraud risk, meet PCI requirements, and maintain trusted payment operations using proven, hardware-backed cryptography.

How payment cryptography protects transactions and reduces risk

Secure ownership of payment cryptographic keys

DPS helps organisations retain full control of payment cryptographic keys using hardware-backed protection that prevents misuse, exposure, and unauthorised access.

Resilient cryptography for always-on payment systems

We design payment cryptographic architectures that deliver high availability and performance, supporting secure, uninterrupted transaction processing at scale.

Reduced fraud risk and compliance burden

By implementing payment cryptography aligned to PCI standards, DPS helps reduce fraud exposure while simplifying compliance and audit requirements.

Why payment cryptography matters

Payment environments are a prime target for attackers due to the direct financial impact of compromise. Weak cryptographic controls can expose card data, enable fraud, and significantly increase regulatory and audit risk.

Payment cryptography ensures sensitive payment data and transaction keys are generated, stored, and used within hardened hardware, reducing exposure and strengthening trust across payment ecosystems.
