The challenge

A global engineering and technology company had moved to Microsoft 365 E5 but still relied on 80 separate security tools, which left it exposed in audits and to advanced attacks. Its Identity Secure Score sat at 15–20%, and email security ran on a third-party service.

What we did

  • Deployed Microsoft Defender for Identity and Microsoft Entra ID Protection, with Microsoft Entra Password Protection, just-in-time admin access through Privileged Identity Management and a Windows Hello for Business pilot.
  • Moved email security from the third-party service to Microsoft Defender for Office 365 for 11,000 users, including mail routing and archiving.
  • Piloted Microsoft Defender for Endpoint, then deployed it to every workstation alongside the existing antivirus.
  • Connected Microsoft Defender for Cloud Apps, with policies for app discovery, threat protection and session control.

What’s next

The company continues to consolidate its security tools onto Microsoft, and it has since governed its data for Microsoft 365 Copilot with Microsoft Purview.
