Application Security Architecture Review
Faced with a critical architectural review of their API-based web and mobile services, one fintech organization had a choice to make — and they chose SIS Cyber. Not because we were the only option, but because our team’s depth and creativity stood apart. The result: a fundamental shift in design strategy, moving the client from a product-first mindset to a process-first one built to last.
The Challenge
Real customer data was about to start moving through a freshly built API-based integration layer, and the design had never been tested by anyone outside the organization. Internal confidence was high — but internal confidence is also, by definition, a blind spot. Once live, any weakness in the architecture would be locked in, far harder to unwind than if it had been caught before launch.
Our Approach
1
Scoped the assessment around the AWS cloud platform and its related components.
2
Reviewed IAM configurations and access control design across the environment.
3
Evaluated API security, including authentication, authorization, and exposure points.
4
Assessed storage security and data-at-rest protections.
5
Mapped network boundaries and trust zones across the cloud architecture.
6
Examined secure integration patterns between cloud services and third-party systems.
7
Designed and led a hands-on hackathon, challenging the organization’s own team to stress-test their security design assumptions in real time.
