Solution

The telecom rolled out Microsoft 365 E5 security features to protect data across its productivity app landscape while providing security teams with Microsoft Sentinel and Microsoft Defender solutions, capping the rollout with Security Copilot. NTT significantly lowered workload and related costs of analyzing PowerShell and other scripts. It onboards junior analysts faster and heightens everyone’s productivity with Security Copilot, providing a higher level of security without expanding its security team. Daily exposure to threats, coupled with a shortage of skilled security personnel, sparked NTT Communications’s search for a connected, proactive, and productivity-enhancing security platform for its global estate.

Data flow

NTT Communications aggregates threat data into Microsoft Sentinel from Defender XDR and related Defender solutions, such as Defender for Endpoint .
