| House security operator at Cypress Creek Renewables | 4.0 | In my experience with Microsoft Defender XDR, I find its advanced threat hunting, effective threat detection, and integration with our systems valuable, though it could improve with a centralized interface. It significantly saves me time, enhancing overall productivity. |
| Business Development Executive at TechnoFirrm | 4.0 | I've used Microsoft Defender XDR for 2.5 years to protect end-user devices, finding it effective and user-friendly, though its automated responses are slow and scalability is limited under certain licenses, especially for SMBs. |
| Director, Sales at a tech vendor with 201-500 employees | 4.5 | As an MSSP, we manage Microsoft Defender XDR for clients, appreciating its integration, identity protection, and ROI.
