Microsoft Defender XDR Reviews Summary
Author infoRatingReview Summary
House security operator at Cypress Creek Renewables4.0In 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 TechnoFirrm4.0I'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 employees4.5As an MSSP, we manage Microsoft Defender XDR for clients, appreciating its integration, identity protection, and ROI. While automation could improve, it replaces legacy tools effectively. Support can be enhanced, but overall, it's our preferred choice.
Vice President, Information Technology at a construction company with 201-500 employees3.5Microsoft Defender XDR helps us proactively detect threats, simplifies incident management, and integrates well with our existing tools, though mobile access and collaboration could improve; overall, it provides essential oversight for our SEC-regulated financial advisory firm.
Manager, Information Technology at a consultancy with 1,001-5,000 employees4.0I've found Microsoft Defender XDR effective for endpoint management with centralized alerts, though fine-tuning incident prioritization and adapting to evolving features remain challenges; overall, it provides solid threat protection and earns an eight out of ten from me.
Information Security Analyst at a educational organization with 10,001+ employees4.5We use Microsoft Defender XDR on Windows systems for secure hybrid identities, offering real-time alerts and timelines. While excellent for Windows, Linux support needs improvement. The transition from a legacy antivirus shows significant ROI, especially in threat isolation efficiency.
Senior System Engineer at a sports company with 5,001-10,000 employees4.0We use Microsoft Defender XDR primarily for threat hunting via email and URL monitoring, finding the Email Explorer invaluable for detection. While backend speed needs improvement, transitioning from Mimecast and Cylance improved our security on Azure significantly.
Network Technician at T. Baker Smith, LLC4.5I've used Microsoft Defender XDR for five years as an intrusion protection tool, valuing its incident visibility, seamless setup, and integration with our ecosystem, which helped us prevent costly breaches and improved our overall security posture.
