API & Application Security Review

Secure software delivery through deep-dive API penetration testing, logic flaw identification, and secure code analysis.

The challenge

Automated SAST and DAST tools flood development teams with false positives while failing to detect complex business logic vulnerabilities. Consequently, applications reach production environments with exploitable API endpoints, violating PCI DSS 4.0.1 Requirement 6 and regional central bank digital channel security directives.

Our approach

Our security engineers conduct manual source code analysis combined with contextual API penetration testing. We evaluate authentication mechanisms, data exposure limits, and backend integrations under real-world threat scenarios, delivering actionable, developer-ready remediation guidance.

Because the reviewer reads your code the way an attacker reads your API, the findings focus on exploitable paths: broken object-level authorisation, workflow bypasses, and trust assumptions between services that scanners cannot model. Each finding ships with a proof of concept and validated patch guidance, so your developers spend their time fixing rather than interpreting.
