Penetration testing in banking environments

Complexity meets Precision

Penetration tests for fully licensed financial institutions regularly present unique challenges. Organizational complexity is typically high in regulated environments, and system landscapes tend to be technically complex. These pentests require a high level of experience and methodological precision.

The scope is usually extensive: online banking platforms, mobile apps, and the underlying APIs form a very integrated system. The testing approach must therefore be comprehensive – technical analysis, business logic, protocol layers, and authorization models all need to be considered in combination. APIs often form the backbone of these infrastructures: extensive, multi-layered, and frequently protected by complex authentication and authorization mechanisms. HMAC signatures or signed payloads are common.

Since many systems are tested regularly, classic "quick wins" are rare. Identifying security-relevant weaknesses often resembles the proverbial search for a needle in a haystack. This makes it all the more rewarding when, after thorough analysis, a previously overlooked or newly introduced vulnerability is found – demonstrating once again the value of a structured approach and long-standing experience.
