Frankfurt Market Landscape

Why cybersecurity & compliance is critical in Frankfurt

The European Central Bank's presence in Frankfurt shapes supervisory expectations for banks and payment institutions across the entire Eurozone, not just Germany.
Frankfurt's concentration of legacy core banking systems creates significant demand for incremental modernization work that avoids risky full core replacements.
Open banking API programs in Frankfurt commonly need to satisfy both PSD2-derived technical standards and BaFin's supervisory expectations simultaneously.

The Challenge

Problems we see teams struggling with

Unreviewed architecture before scale-up

Security debt compounds quickly once a platform is handling real transaction volume and regulator scrutiny.

API and application vulnerabilities

Unsecured APIs are one of the most common entry points for breaches in fintech and payments platforms.

Manual AML/KYC processes

Manual identity verification and sanctions screening slow onboarding and create compliance gaps.

Audit and licensing readiness gaps

Missing logging, access controls, or reporting capability can block a licensing application or banking partnership.

No incident response plan tested before it's needed

The first real test of an incident response plan shouldn't be an actual breach — untested plans routinely fail at the exact moment they matter most.

Sanctions screening gaps at onboarding

Screening that runs once at account opening but never again misses risk that emerges after a customer relationship is already established.

Our Approach

How we deliver cybersecurity & compliance in Frankfurt

Secure architecture review

Threat modeling and architecture review across infrastructure, application, and data layers before you scale.

API security engineering

OAuth2/OIDC hardening, rate limiting, input validation, and abuse protection for public and partner APIs.

AML/KYC compliance software

Identity verification, sanctions/PEP screening, and transaction monitoring workflows built into your platform.

Penetration testing & remediation

Independent penetration testing coordination with hands-on remediation of findings.

Smart contract & blockchain security

Security review for on-chain systems, custody flows, and wallet infrastructure.

Audit-ready logging & reporting

Immutable audit trails and regulator-ready reporting exports built into the platform, not bolted on.

Ongoing sanctions and PEP re-screening

Continuous re-screening against updated sanctions and politically-exposed-person lists, not just a one-time check at onboarding.

Incident response planning and testing

A documented, rehearsed incident response plan so the first time your team executes it isn't during an actual breach.
