Web application testing for a finance industry
We work with various sectors and possess extensive expertise in testing applications designed for the financial industry. Starting from banking applications and APIs (like PSD2), through corporate banking applications (with complex transaction authorization schemes), to investment platforms and brokerage house software. We prioritize the security of the user accounts and their funds, focusing on:
User account-related flows:
- user authentication flow (biometrics, MFA, password complexity, account lock, etc.),
- user registration (via digital ID, via another bank/identity provider, etc.)
- user account recovery flow
- user profile modification (changing password, changing phone, MFA, adding new mobile device, etc.)
Transaction flows:
- transaction authorization (second factor as SMS, cryptographic card with PIN, hardware token, etc.)
- transaction business limits and validation (getting a loan larger than the risk rating indicated, returning a deposit to an external account, bypassing the authorization step, etc.)
Not only external applications, but also internal ones. We also work with various fintech companies, ranging from different payment providers to lending platforms.
We tested various e-commerce platforms, focusing on payment flows, discount coupons, and delivery management.

Collaboration
We are not the type of company that goes silent during the engagement, just sending two emails (one when we start and a second one with the report).
It’s important to be on the same channel as the application team, such as Slack or Teams. We ask questions to understand and show what does not work as expected. We explain what we do and teach about what we consider important.
We help design and securely implement remediations, and we recommend the next steps during the test. We are also keen on learning, understanding why something is done in a certain way and not another, and what the pros and cons of a given code piece or module are. It makes us better at what we do, seeing the applications team’s perspective.
Expertise
We rely heavily on industry standards (OWASP projects, RFCs, Hacktricks), as well as our over 20 years of experience and a culture of knowledge sharing. This experience is built on a strong foundation:
- thousands of penetration tests delivered,
- security research presented at major security conferences around the world.
Our in-house checklists cover all popular technologies and frameworks, ensuring a reproducible set of test cases.
DORA compliance
Web application testing can contribute to the compliance with DORA principles. It aligns with DORA’s focus on securing software components.
