Case Study: Global Leadership Advisory and Search Firm protects critical data and reduces false positives 90-95% with CRITICALSTART MDR and Microsoft Defender for Endpoint

Global Executive Talent Leader Protects Core Business with CRITICALSTART MDR and Microsoft Defender for Endpoint

Global Leadership Advisory and Search Firm, a global executive talent leader operating 48 offices in 23 countries with three redundant data centers, needed to protect massive volumes of sensitive data and monitor endpoints across a distributed estate without simply increasing headcount. They deployed Microsoft Defender for Endpoint for endpoint detection and response but quickly realized they needed a Managed Detection and Response provider to handle the alert volume and provide 24x7 threat monitoring—selecting Critical Start to fill that role.

Critical Start implemented its MDR for Microsoft Defender for Endpoint, creating a trusted registry to reduce noise, providing continuous SOC analysis, and giving the firm an intuitive portal for visibility. Within a 6–8 week deployment false positives fell by 90–95% and were nearly eliminated after 45 days; Critical Start’s SOC also detected and contained a USB‑borne infection before it propagated, reducing workload, improving visibility, and materially lowering breach risk.
