The European Payments Initiative (EPI) is reshaping how European banks, PSPs, and merchants handle payments. Its Wero wallet has already reached tens of millions of users across Germany, France, Belgium, and the Netherlands, with more markets launching soon. To participate, EPI requires every issuer, acquirer, and technical service provider to pass a security evaluation before certification — and to keep passing it through recurring follow-up audits. Falling short on a requirement mid-audit doesn't just cost you time; it can delay your ability to go live in a market where competitors are already onboarding users.
- Wallet Evaluations
- PSP Evaluations
- Design & Documentation Review
Certify standalone and embedded wallets
We evaluate standalone digital wallets and wallets embedded within PSP solutions against EPI security requirements, covering mobile security, cryptography, and transaction integrity.
Cover both sides of the transaction
Isolate bottlenecks across GPU compute, memory, KV-cache, storage, PCIe, RDMA, and orchestration layers. In one-arm mode, KAI Infrerence Builder acts as a high-scale inference client, driving prompt-shaped workloads directly into inference stacks so network teams can pinpoint issues faster and fine-tune performance with precision.
Catch issues before testing begins
We assess your architecture and technical documentation against EPI requirements early, surfacing gaps while they're still cheap to fix.
Mobile Security
Assessment of your mobile application's good practices and security mechanisms.
Cryptographic Analysis
Validation of encryption algorithms, key exchange, and secure key storage.
- Authentication Protocols
Review of biometric, multi-factor, and token-based mechanisms.
- Transaction Integrity
Assessment of data authenticity, consistency, and safeguards against replay or tampering.

Frequently Asked Questions
EPI is a collaboration among European banks and financial service providers to deliver a unified digital wallet and account-to-account payment solution for the region, branded Wero. It supports peer-to-peer and online payments today, with in-store payments following in the coming years.
Any issuer, acquirer, payment service provider (PSP), or technical service provider (TSP) that wants to enable customers to send or accept payments through EPI must pass a security evaluation before certification, and pass recurring follow-up audits to keep it.
Wallet evaluations assess standalone or embedded digital wallets. PSP evaluations cover both the consumer and acceptor sides of the transaction chain. TSP reviews apply to technical providers supporting an issuer or acquirer's EPI-relevant services, including backend and payment processing systems.
EPI requires an initial audit followed by regular follow-up audits. The exact cadence depends on your role in the program — issuer, acquirer, or TSP — and Keysight can help you plan for it as part of your evaluation.
Yes. If you're already pursuing EMVCo, Visa, Mastercard, or PCI certifications, Keysight can align the evaluations to reduce duplicate work and shorten your overall compliance timeline.
Timelines vary by scope and how ready your documentation is going in. Starting your design and documentation review early — well before you plan to launch — is the single biggest factor in avoiding delays.
