A leading fintech company commissioned us to conduct a security review of their cloud-based SaaS platform that supports financial institutions with advanced analytics and reporting tools. The goal was to minimize potential risks and protect the platform against current and future threats.

Overview
Our comprehensive security review focused on identifying and addressing vulnerabilities in the platform’s infrastructure, data protection mechanisms, and access controls. The project aimed to ensure the highest level of security for financial institutions using the platform’s analytics and reporting capabilities.
Challenges and Risks
Insufficient Protection of Sensitive Data
Vulnerabilities in data encryption could lead to unauthorized access to sensitive financial data.
Inadequate Access Management
Weaknesses in authentication mechanisms could allow attackers to gain administrative rights.
Potential API Vulnerabilities
The interfaces could be exploited to perform unauthorized transactions or manipulate system data.
Possible Attacks on Cloud Infrastructure
Vulnerabilities could lead to Denial-of-Service (DoS) attacks or data loss.
Approach
White-Box Tests
We analyzed the platform’s source code to identify internal vulnerabilities such as faulty logic, insufficient data validation, or incorrect access rights.
Black-Box Tests
Simulated attacks without knowledge of internal structures allowed us to evaluate the platform like an external attacker. The focus was on publicly accessible areas of the infrastructure and API interfaces.
Penetration Tests
With realistic attack scenarios, we tested the robustness of the cloud environment and susceptibility to data exfiltration, manipulation, and service interruptions.
Security Policy Review
We evaluated existing security policies and suggested improvements to close potential entry points.
Results
- 17 Critical Vulnerabilities Resolved: Including issues in API security and access control.
- Enhanced Data Security: Improved encryption protocols protected sensitive data from unauthorized access.
- Stronger Resilience: The platform was secured against DoS attacks and other potential threats.
- Regulatory Compliance: The platform was successfully adapted to relevant security standards.
