Case Study
Securing a Global Payments Platform at Scale
How a Fortune 500 fintech reduced critical findings by 91% within two assessment cycles.
The challenge
A global payments platform processing millions of daily transactions needed to harden its API layer and cloud infrastructure ahead of a major regulatory audit, without disrupting a continuous deployment cadence shipping dozens of times per day.
The engagement
RedShield Defense combined penetration testing, secure code review, and cloud security engineering across a 12-week program, embedding directly with the client's platform team to remediate findings in real time rather than waiting for a final report.
The outcome
Critical and high-severity findings dropped 91% between the first and second assessment cycles. The client passed its regulatory audit with zero material findings and has retained RedShield Defense for ongoing quarterly assessments.
