Case Study: Murex secures and modernizes its capital markets platform with Semmle

Securing and modernizing the world's leading capital markets platform

Murex, a leading capital markets platform provider in FinTech, needed a way to secure a very large, complex codebase, support a flexible architecture, and raise development standards across many teams. With millions of lines of code, multiple languages, and deeply integrated dependencies, the company required a solution that could analyze its specific frameworks without generating excessive false positives. Murex turned to Semmle for customizable code analysis and security review.

Using Semmle, Murex built highly tailored analyses for security, dead code detection, modularization, and platform transformation. The vendor helped Murex optimize its move from 32-bit to 64-bit architecture, reducing memory consumption by 20% versus the pre-upgrade baseline, while also supporting ongoing quality and refactoring efforts across teams. Semmle’s flexible queries became part of continuous development and release gating, helping Murex maintain secure, efficient code at scale.
