Fintech is usually prone to cyber threats of various scopes and sizes. The stakes are often high since fintech companies deal with highly sensitive customer information – from bank account details to personal data.
A Middle-East headquartered fintech company approached Wattlecorp to set up a reliable cybersecurity system for them. They offer full-fledged financial services to different businesses across industries. In addition to these, they have also built many in-house APIs for third-party vendors. This significantly increased the risk of exposing their system to vulnerabilities.
The Challenge
Managing the API ecosystem was difficult because company had multiple in-house APIs and a growing list of integrations. Each one added its own security concerns.
What made it more complicated was working with third-party vendors. With every connection opening the door to potential supply chain attacks and unauthorized access, the need to safeguard sensitive data was critical.
The client also had to follow strict rules like GDPR and PCI-DSS. A single mistake could lead to big fines or lost customer trust.
Wattlecorp’s Intervention
We kicked things off with a full security audit.
We went through all their APIs and third-party integrations. We looked for weak spots, misconfigurations, and any place where sensitive data could slip through.
Then we moved to threat modelling. We mapped out how an attacker might break in—especially around sensitive data and high-risk connections. Once we found the paths, we shut them down.
Next, we cleaned up the code.
We fixed the flaws and applied secure coding practices. We encrypted the client’s sensitive data. We improved the way users can log in.
Finally, we removed access points that weren’t found a necessity anymore.
It was about making sure everything was tight, clean, and hard to break into.
To keep things safe long term, we set up live API monitoring. Any suspicious behaviour was flagged right away, which helped the team act fast when something seemed off.
Finally, we ran regular penetration tests to check if any new threats had crept in. This way, the security stayed strong in line with the ecosystem.
The Results
We reduced security flaws in the API ecosystem by 70%.
Our client met GDPR and PCI-DSS standards, which helped them ward off compliance penalties at best.
The outcome could have been no better than having their third-party vendors gain more trust in the system, making way for smoother partnerships.
The team now detects and responds to threats faster than ever before.
Wattlecorp didn’t just plug the gaps. We gave the client confidence in their systems—and the ability to scale securely.
