Case Study: Mutual of Enumclaw transforms legacy systems and reduces troubleshooting time with Epsagon

How Mutual of Enumclaw Transformed from AS/400 to Modern Application with Confidence

Mutual of Enumclaw, a 100+ year-old insurance company serving six western states, was modernizing core policy systems from AS/400 and mainframe infrastructure to a cloud-native architecture. As the company expanded into microservices on AWS ECS and AWS Lambda, its engineers faced growing observability challenges across a highly distributed environment.

Epsagon provided distributed tracing and unified visibility across Mutual of Enumclaw’s AWS environment, helping the team monitor Lambda functions, ECS clusters, logs, traces, and resource usage through a single dashboard. With Epsagon, the company reduced error rates by up to 80% and troubleshooting time by up to 85%, improving developer velocity, speeding MTTR, and enabling the team to scale modern applications more effectively.
