Case Study: a global telecommunications organization achieves zero-downtime .NET modernization with UST Global

a global telecommunications organization cuts maintenance 30% with UST Global

UST Global helped a global telecommunications organization address the growing business risk posed by its aging legacy .NET application. End-of-life frameworks limited security and modern IAM controls, while support teams were burdened by excessive time spent on regressions and recurring fixes.

UST Global modernized the platform by upgrading it to .NET 8 with short, staged releases and integrating OpenID Connect for authentication. This solution resulted in a 30% reduction in maintenance effort, a 20% increase in team productivity, and a 40% stronger security posture, all achieved with zero downtime to business operations.
