UnderDefense: 85% fewer incidents after QRadar to Elastic migration

A SaaS provider of enterprise digital safety software significantly improved its security operations by migrating from a legacy QRadar system to Elastic Security on Elastic Cloud, with the assistance of UnderDefense, an Elastic partner. This transition involved a comprehensive log ingestion audit, the creation of over 100 custom detection rules aligned with the MITRE ATT&CK framework, and the development of 25 tailored Kibana dashboards for different organizational roles. As a result, the company achieved an 85% reduction in security incidents and a 61% decrease in mean time to respond, transforming its two-person security team from reactive triage to proactive threat hunting. The migration also addressed compliance challenges by implementing audit-ready data retention with Elastic frozen-tier snapshots, optimizing storage costs and ensuring regulatory adherence. This shift not only enhanced operational efficiency and visibility but also strengthened the company's market position by providing documented, reproducible audit evidence that meets enterprise customer demands.
