ROI

Sentiment score
6.7
Microsoft Defender XDR provides high ROI by consolidating security tools, streamlining operations, and enhancing security, despite licensing costs.
Sentiment score
7.5
SentinelOne Singularity Complete cuts costs by boosting productivity, preventing threats, and reducing ransomware risks, offering quick ROI.
We can quarantine and isolate a device within minutes.
Microsoft Defender XDR has saved me at least 50% of my time.
Ever since we turned on the M5 feature set back in June, we have seen a reduced number of potentially malicious clicks and faster alerting when incidents occur.
Since then, I have not faced any intrusions, which is one reason I chose SentinelOne over ESET.
We have not faced any attacks since we implemented it.
It has absolutely helped reduce our organizational risk.
 

Customer Service

Sentiment score
6.2
Microsoft Defender XDR's support is timely and responsive, yet smaller organizations experience slower, less effective assistance than larger ones.
Sentiment score
7.2
SentinelOne Singularity Complete offers quick, knowledgeable support with remote sessions, though some desire faster, interactive phone or chat options.
You get stuck in low-level support for way longer than you should, instead of them escalating the issue up the chain.
It's critical to escalate SEV B issues immediately to a domestic engineer.
Once issues are escalated to the second or third layer, the support is much better.
They do a great job of figuring out the problem and pointing you to generic documentation or working with you to fine-tune a solution.
We are using the automated email process for support, and they respond within an hour or two hours sometimes.
A chat service would be beneficial.
 

Scalability Issues

Sentiment score
7.6
Microsoft Defender XDR scales well for various organizations, efficiently supporting growth and flexibility despite some network deployment challenges.
Sentiment score
8.1
SentinelOne Singularity Complete scales efficiently, smoothly handling deployments, adding agents, and supporting growth across diverse IT infrastructures.
Microsoft Defender XDR shows tremendous scalability, much more so than on-premises solutions.
Microsoft Defender XDR scales pretty well.
It is suitable for enterprise-level deployment but has room for improvement.
It's all auto-scale and auto-categorized, configuring automatically.
The tool's built-in automation for deploying the agents works well for large infrastructures like mine.
My deployment is relatively small, and SentinelOne Singularity Complete works within those constraints.
 

Stability Issues

Sentiment score
8.0
Microsoft Defender XDR is praised for high stability, reliable performance, minimal issues, frequent updates, and prompt issue resolution.
Sentiment score
7.9
SentinelOne Singularity Complete is praised for stability, performance, and proactive updates, despite occasional third-party software conflicts.
The service has remained consistently online, with any issues isolated to specific components, suggesting a well-designed and modular architecture.
The services within our ecosystem have been reliable, meeting their SLAs.
It provides high-fidelity signals.
It has caused problems with interoperability between third-party tools, which could lead to entire servers crashing or specific tools failing.
This indicates room for improvement in stability when interacting with other solutions.
Initially, there were issues, particularly on the management side, but now the console is much more stable.
 

Room For Improvement

Microsoft Defender XDR requires enhancements in speed, integration, automation, AI, ease-of-use, and industry-specific threat intelligence.
SentinelOne Singularity Complete needs improvements in updates, false positives, integration, pricing, customization, access control, and threat detection.
The licensing process needs improvement and clarification.
Improvements are needed in automated response capabilities.
Some inconsistencies exist between blades, which could be improved for a more seamless user and UI experience.
The only thing that prevented the attack from succeeding was a free version of Malwarebytes.
Providing a single pane of visibility for the end user would be beneficial.
It's challenging to prevent a user from manipulating their privileges or someone else's of others, and it's difficult to control what users can access at the organizational level.
 

Setup Cost

Microsoft Defender XDR pricing is seen as complex but fair, with high costs alleviated in bundled Microsoft 365 packages.
SentinelOne Singularity Complete provides cost-effective endpoint security, with competitive pricing justified by its comprehensive and flexible features.
There are certainly savings when using Microsoft Defender XDR, which can range from 30%, 40%, and even up to 50%.
I would rate the pricing as eight out of ten, indicating it is a reasonable cost for the product.
Microsoft purposefully obfuscates this through marketing ploys to hide costs.
If you want protection, you have to pay the price.
There are other products that are less expensive, but I tell my clients that in security, they cannot cut corners or look for the cheapest solution.
They counted many of the instances and licenses as duplicates despite them only being alive once, which was frustrating.
 

Valuable Features

Microsoft Defender XDR integrates tools for comprehensive security, offering threat detection, automation, identity protection, and enhanced efficiency.
SentinelOne Singularity Complete is lauded for AI threat detection, automation, user-friendly interface, and efficient endpoint security without cloud reliance.
With Microsoft threat intelligence information, it detects various types of threats, including insider attacks, malicious content, and data exfiltration.
This allows us to secure our systems in advance and proactively improve security, rather than waiting for incidents to occur.
Once we have it on the security dashboard, we can see a real-time storyline.
I have an advanced app providing visibility of all my endpoints, which was not the case before.
SentinelOne has a feature to decommission automatically, which has been fantastic.
There's also automation that gives my team free time, preventing them from having to look for every alert.

Featured Reviews

MohtesanShaikh - PeerSpot reviewer
Experience improves security management and simplifies threat protection
I have created automated investigations, and while they work, they operate rather slowly in the Microsoft portal. If I automate something, it takes considerable time; if I do it manually, I can complete it in a quarter of the time. The automation response being slow is the main concern; when an incident occurs or if I run a remediation, it takes significant time to complete the remediation. There are some limitations regarding the scalability of Microsoft Defender XDR with specific licensing. For SMB customers, there is only Microsoft Defender for Business, and if they want more features such as XDR features and automation investigation or incident response, they need to purchase Defender for Endpoint. We are currently using the EDR.
Vidya Shree - PeerSpot reviewer
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.
