Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.1
Microsoft Defender for Endpoint offers significant ROI with cost savings, seamless integration, and real-time protection against ransomware attacks.
Sentiment score
7.5
SentinelOne Singularity Complete cuts costs by boosting productivity, preventing threats, and reducing ransomware risks, offering quick ROI.
Without detection and protection measures, organizations would face substantial payments and reputational damage, including the necessity to inform customers about data breaches, potentially leading to loss of business.
We have seen a return on investment when using Microsoft Defender for Endpoint, as it saves labor by reducing the need for staff to focus on it.
The biggest return on investment for me when using Microsoft Defender for Endpoint is the time saving.
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
6.6
Many users find Microsoft Defender for Endpoint reliable, but support experiences vary, with premium support offering quicker assistance.
Sentiment score
7.2
SentinelOne Singularity Complete offers quick, knowledgeable support with remote sessions, though some desire faster, interactive phone or chat options.
The level-one support seems disconnected from subject matter experts.
I rate Microsoft support 10 out of 10.
Due to our size, we don't have access to direct technical support, but the knowledge base, Microsoft Learn, and the articles available are really good.
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
7.7
Microsoft Defender for Endpoint is scalable and integrates well with Microsoft’s ecosystem, despite needing improvements for handling massive data.
Sentiment score
8.1
SentinelOne Singularity Complete scales efficiently, smoothly handling deployments, adding agents, and supporting growth across diverse IT infrastructures.
We managed to scale it out in a short amount of time, with two months of planning and three months of implementation on 10,000 computers.
Microsoft Defender for Endpoint is scalable enough to handle various devices across environments, whether they are laptops, Android devices, or operating in hybrid environments.
Compatibility is its main feature.
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
7.9
Microsoft Defender for Endpoint is praised for its reliability and stability, with minor concerns about resource intensity and performance.
Sentiment score
7.9
SentinelOne Singularity Complete is praised for stability, performance, and proactive updates, despite occasional third-party software conflicts.
I haven't seen any outages with Microsoft.
I rate Defender 10 out of 10 for stability.
Defender for Endpoint is extremely stable.
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 for Endpoint faces interface complexity, slow detection, high CPU usage, integration issues, and seeks improvements in multiple areas.
SentinelOne Singularity Complete needs improvements in updates, false positives, integration, pricing, customization, access control, and threat detection.
Repeated interactions are necessary due to Level One's lack of tools and knowledge, hindering efficient problem-solving and negatively impacting our experience with Microsoft support.
In contrast, competing products offer reduced pricing for long-term commitments, which makes it difficult for us in that environment.
We use Microsoft partners to help govern the platform, and as part of an alliance, we want to gather data from each tenant and combine them for a complete view.
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 for Endpoint offers flexible pricing, making it competitive and cost-effective compared to standalone security products.
SentinelOne Singularity Complete provides cost-effective endpoint security, with competitive pricing justified by its comprehensive and flexible features.
Given our extensive Microsoft licensing, transitioning to Defender for Endpoint did not affect licensing costs.
It costs $15 per VM for the P2 plan, which is seen as affordable for customers.
The pricing, setup, and licensing were very easy and simple.
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 for Endpoint excels with seamless integration, advanced threat intelligence, AI-driven protection, and continuous cloud-based security management.
SentinelOne Singularity Complete is lauded for AI threat detection, automation, user-friendly interface, and efficient endpoint security without cloud reliance.
Defender for Endpoint's coverage across different platforms in our environment is pretty good. We have devices running Linux, Mac OS, Windows, iOS, and Android. It covers all of them.
Microsoft Defender for Endpoint provides a unified management interface allowing customers to manage their on-premises and hybrid infrastructures from a single pane.
One of the best features of Microsoft Defender for Endpoint is its database for identifying zero-day attacks or malware attacks.
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

NaySan @ Suraj Verma - PeerSpot reviewer
Has effectively blocked sophisticated attacks and malicious activities while providing excellent support
Microsoft Defender for Endpoint is very good, but one suggestion is that in some products, we may need to configure security-related settings, whereas Microsoft Defender for Endpoint works completely differently, providing automatic recommendations and actions that we may need to perform ourselves. Regarding the pricing of Microsoft Defender for Endpoint, during the last three years, we set up the product and sold it, but we faced difficulties because Microsoft pricing is always the same. For example, whether I purchase Microsoft Defender for Endpoint for one year or for the next three years, the pricing remains constant with no discounts available. In contrast, competing products offer reduced pricing for long-term commitments, which makes it difficult for us in that environment. Microsoft should consider this option to remain competitive, but otherwise, everything else is fine.
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.
