Open Banking has transformed how financial data flows between institutions, businesses, and consumers. By allowing authorised providers to access bank account information securely and transparently, innovation has accelerated across payments, lending, accounting, personal finance, retail, and more.
But alongside this new wave of connectivity comes an equally important responsibility: Open Banking security. When financial data is shared through APIs, the expectation of trust must be absolute. Businesses rely on their Open Banking providers not only for connectivity, but for the assurance that every connection is protected, monitored, and compliant.
At finker, this responsibility has always been a cornerstone of how we deliver regulated, PSD2-compliant Open Banking services. Open Banking security is not an add-on to our platform, it is embedded into our architecture, controls, and mindset behind everything we build.
Why Cybersecurity matters more than ever in Open Banking?
Open Banking introduces clear benefits: transparency, competition, and innovation. However, it also shifts the financial ecosystem into a more interconnected environment, where multiple parties engage in the movement of sensitive data.
This means new risks must be managed carefully:
-
Increased attack surface due to multi party API connections.
-
Higher stakes, as bank account information is among the most sensitive data a consumer or business holds.
-
Regulatory scrutiny, with PSD2 and the Bank of Greece’s requirements for AISPs demanding robust security measures.
-
Real-time expectations, where threats evolve quickly and response must be immediate.
To meet these challenges, Open Banking providers must combine regulatory discipline with advanced cybersecurity capabilities and that requires both expertise and dedicated infrastructure.
How finker approaches security
finker delivers Account Information Services (AIS) through PSD2 regulated, secure APIs that allow businesses to innovate without compromising on trust. Our approach to security includes:
-
Bank grade authentication and authorisation flows
-
Regulatory oversight by the Bank of Greece as an AISP
-
Strict data governance and encryption standards
-
Continuous platform monitoring and internal controls
-
Privacy-by-design principles in all services
Upgrading our security posture is not about closing gaps, it is about staying ahead of what Open Banking demands today and what it will demand tomorrow.
