Industry stakes

In fintech, a mistake is not recoverable

Fintech is a regulated market where errors cost dearly: a payment bug, a security flaw or an imprecise calculation can lose millions and destroy customer trust. PSD2, GDPR, KYC/AML, ACPR requirements, MiCA for crypto — the regulatory frame is dense.

Your first enterprise customers, banking partners or regulators will audit your stack before signing. A poorly designed security architecture blocks deals for months.

Our approach

A fintech that passes audit and holds production

Encryption in transit and at rest, mandatory MFA, tokenization of sensitive data, immutable logs, strict environment separation: the stack is audit-ready from day 1, not patched late.

We anticipate questions from DPOs, CISOs and auditors from scoping. Security documentation, incident procedures, continuity plans: everything ready when needed.

Frequently asked questions

Stripe, Adyen, Lemonway, Checkout.com, Mangopay for the most common. For direct banking integrations (SEPA, SWIFT, Open Banking), we have experience.

We help you pick the right PSP based on your volumes, business model and regulatory constraints.

PSD2-compliant strong authentication (SCA), integration of specialized KYC partners (Sumsub, Onfido, Veriff) to automate onboarding while respecting AML requirements.

We scope these constraints upfront with your DPO or legal firm — our role is translating compliance into architecture decisions.

Yes. Security documentation, incident procedures, audit logs and continuity plans are produced continuously, not at the last minute.

Our fintech clients regularly pass audits smoothly thanks to this discipline.
