Executive SummaryUpdated on Jul 13, 2025

SentinelOne Singularity Complete and Microsoft Defender for Business compete in the cybersecurity sector, specifically focusing on endpoint protection. SentinelOne appears to have the upper hand in autonomous threat mitigation and AI-driven real-time protection, which contributes to a more comprehensive security suite.

Features: SentinelOne Singularity Complete offers rollback functionality, autonomous threat mitigation, and AI capabilities that provide real-time protection and high visibility into threats. Microsoft Defender for Business is known for its seamless integration with the Microsoft ecosystem, which provides a unified security approach with other Microsoft products. However, it lacks the advanced rollback and behavior analysis features present in SentinelOne.

Room for Improvement: SentinelOne could refine its user interface customization and expand support for legacy systems. Users report challenges with policy setup complexity. Microsoft Defender for Business needs enhancements in its management console, better integration with non-Microsoft tools, and streamlined deployment processes for improved threat management.

Ease of Deployment and Customer Service: SentinelOne supports deployment in multiple environments including private and public clouds, with customer support praised for its responsiveness. However, improvements in Tier 1 interactions are needed. Microsoft Defender integrates well with hybrid and on-premises setups due to Microsoft's network, but users experience variability in support response times and hands-on assistance.

Pricing and ROI: SentinelOne is often seen as expensive but offers significant ROI, especially for larger enterprises, due to its robust features. Microsoft Defender, included with certain Office 365 subscriptions, offers cost benefits for existing Microsoft users but can be costly on a standalone basis. Feedback on pricing value is mixed, especially for smaller organizations, with appreciation for its ecosystem integration benefits.

Product deployment protects assets but needs improvement in system support
I am doing maintenance for Microsoft Defender for Business, and I'm currently working with it. We don't need to use the latest version of Microsoft Defender for Business. We still use the latest virus definition file that Microsoft Defender for Business has automatically updated. We implement a basic update mechanism. Our compliance division manages how many servers and PCs we have and whether those servers have antivirus solutions. I am not certain about how Microsoft Defender for Business helps with AI-driven security strategies. I just use it normally and don't know if it uses AI technology. I rate Microsoft Defender for Business a six out of ten.

Easy to manage, zero-trust option and supports both Linux and macOS
SentinelOne supports both Linux and macOS. All SentinelOne features were equally supported across Windows, Linux, and Mac, whereas CrowdStrike was more heavy on the Windows side. They did not support all features on Linux. The Singularity console provides a unified view. But we already had similar dashboards available to the ones we had engineered ourselves. So it's not a deal-breaker. For us, it was about supporting multiple operating systems. That was more important. So, these dashboards we have are third-party tools integrated with SentinelOne.
