Cybersecurity for Payment Service Providers
PSPs sit directly inside the transaction flow — the risk surface isn't a supporting system, it's the business itself. RETIS assesses that flow end to end, from integration points through to settlement and monitoring.
Where payment service providers carry distinct cyber risk
These patterns come from how payment service providers actually operate day to day — not a generic enterprise risk list with the sector name swapped in.
Transaction Flow Security
Payment processing logic and infrastructure are the core asset — and the core target.
Payment Control Expectations
Partners and banks expect controls consistent with recognised payment industry practice.
Settlement & Reconciliation Integrity
Errors or exposure in settlement processes carry direct financial consequences.
API & Partner Integration Exposure
Every merchant and partner integration expands the attack surface.
Fraud Detection & Monitoring
Real-time visibility into anomalous transaction activity is core to PSP risk management.
Incident Response Under Real-Time Pressure
A PSP incident affects live transaction flow — response readiness has immediate commercial impact.
Where to start
Not every service applies equally — these are the ones payment service providers most often need first.

Case studies for this sector are in progress
RETIS publishes case studies only with client authorisation, and only once an engagement is complete. As sector-specific engagements conclude, anonymised or named case studies (where permitted) will be added here — we won't publish placeholder results in the meantime.
Questions from payment service providers
All testing is scoped, authorised and conducted under clearly defined rules of engagement agreed in advance — nothing is tested without your explicit sign-off.
Yes — documentation and findings can be structured to support the due-diligence conversations you have with banking and partner relationships.
No. RETIS provides risk assessment and advisory; it does not issue or claim formal payment-industry certifications unless the relevant licensing is explicitly in place.
An initial briefing call is the fastest way to understand timeline — most engagements can begin scoping within days of that call.
