Project Director at a tech services company with 1,001-5,000 employees
Quite effective for preventing virus infections, data leak, or other security breaches
Pros and Cons
- "I am using it for very simple purposes. It is perfect and quite effective. I have been using it for a while, and I have never had any virus infection, data leak, or other security breaches. It works fine for standalone purposes. If you log on to OneDrive, it has ransomware protection."
- "Windows Firewall is integrated with Windows Defender. Over the last few days, I have had a problem with defining a wildcard on Windows Firewall. For example, I wanted to pull out the connection of my program and install a software package with a lot of executable files. I wanted to prevent it from accessing the internet. I could not select executables by using a wildcard. I had to select a single executable with its full name."
What is our primary use case?
Windows Security Essentials is available on Windows 7 and Windows 10. I'm using Windows Defender, and the agent is deployed on-premises on my laptop. I don't know if it has some background cloud services.
I use it for flash memories, portable memories, real-time scanning, threat protection, and capturing the data downloaded from the internet.
What is most valuable?
I am using it for very simple purposes. It is perfect and quite effective. I have been using it for a while, and I have never had any virus infection, data leak, or other security breaches.
It works fine for standalone purposes. If you log on to OneDrive, it has ransomware protection.
What needs improvement?
Windows Firewall is integrated with Windows Defender. Over the last few days, I have had a problem with defining a wildcard on Windows Firewall. For example, I wanted to pull out the connection of my program and install a software package with a lot of executable files. I wanted to prevent it from accessing the internet. I could not select executables by using a wildcard. I had to select a single executable with its full name.
For how long have I used the solution?
I've been using this solution for five years or more.
What do I think about the stability of the solution?
It is very stable.
What do I think about the scalability of the solution?
I don't know about scalability because I have always used it on a single laptop, but I'm sure that there are business options, and you can use it on Windows 7 computers. It must be very scalable.
How are customer service and technical support?
I live in Iran, and there is no product support in Iran. If there is a technical issue, I prefer to use online information and resources, such as forums and Wiki pages, to resolve the issue.
How was the initial setup?
It is very easy to install. It is preinstalled when you install Windows. If you install other antiviruses, you have to deactivate it in order to use third-party products.
What other advice do I have?
Microsoft has started to integrate the interface with new Windows 10 settings. Previously, there was a lack of information. Users weren't aware of the status of the product in terms of what it was doing on your computer and whether it was actually protecting you or not. In the background, it must have been doing its job, but you couldn't be very well aware of the status of the software. All those issues are now resolved. The information now is very handy, and the user interface is also great. I would recommend this solution to others.
I would rate Microsoft Defender Antivirus a nine out of ten.
Which deployment model are you using for this solution?
On-premises

Manager Cyber Defense Operations Centre at a tech services company with 201-500 employees
Affordable and straightforward without much to improve for personal use
Pros and Cons
- "It is easy to install and use requiring little maintenance but applying updates."
- "It is inexpensive but could be cheaper like anything else."
What is our primary use case?
I installed Windows Defender for personal use for my protection of my personal PC. I use it as an antivirus system so that I do not have any exposure to viruses on my PC. Obviously, I do not want to leave my PC open to virus threats. I have only used it on my personal PCs with the license I got for Office 365. I keep my patches and descriptions updated on my PC.
Defender is installed only one one of my laptops. I am sure I will continue using it there as long as the licensing is valid.
What is most valuable?
I really have not really worked with it that much to be able to customize my approach with it or anything like that. It pretty straightforward to install and use.
What needs improvement?
I do not find that there is very much about it that needs to be improved. Everything can be cheaper I am sure. So, it could be less expansive.
For how long have I used the solution?
It has been about six months now since I started using Microsoft Windows Defender.
What do I think about the stability of the solution?
It is stable.
What do I think about the scalability of the solution?
I am sure it is a scalable product.
Which solution did I use previously and why did I switch?
I was just using or trying to get a personal PC secure using a product I got as part of the Office 365 package. There was no previous product installed.
How was the initial setup?
I found that it was pretty straightforward to install and use. You install it and it is working almost immediately.
What's my experience with pricing, setup cost, and licensing?
I think that the product is affordable. At least it was for me. It is part of the Office 365 package.
What other advice do I have?
I have used it enough to be sure that I could recommend it for home use on a PC.
On a scale from one to ten (where one is the worst and ten is the best), I would rate Defender as a nine-out-of-ten based on my experience.
Which deployment model are you using for this solution?
On-premises
Disclosure: I am a real user, and this review is based on my own experience and opinions.
Deputy Director at BG Service
Intuitive, easy to use, and good for people who don't have much experience in security
Pros and Cons
- "The most valuable features are that it's easy to use and the updates are very simple."
- "I would like to be able to set up any kind of protection I want in the firewall, any IP address or any number."
What is our primary use case?
Our primary use case of this solution is to defend from viruses.
What is most valuable?
The most valuable features are that it's easy to use and the updates are very simple.
What needs improvement?
I would like to be able to set up any kind of protection I want in the firewall, any IP address or any number.
I would like to be able to customize my protection on the dashboard.
What do I think about the stability of the solution?
It's a good product but it is limited in some cases. I had a bad experience because a few weeks ago I was in Seoul in Korea and with my Dropbox, my children did some things on my computer at home and I got ransomware to Defender and it corrupted my whole Dropbox. The stability can use improvement.
What do I think about the scalability of the solution?
It's easy to document new people. With the dashboard, I can set up rules to protect myself from any IP address coming from an external network.
We use this solution daily. We don't have plans to increase the usage.
We have around ten to twelve users. They are only users, not admins. We only require one admin. A guy sometimes comes to set up a desktop and do the configuration.
How are customer service and technical support?
We have never needed to contact their technical support.
What's my experience with pricing, setup cost, and licensing?
The cost is per-user. We pay more for an Enterprise license.
What other advice do I have?
I would say this is a good product. It's very intuitive, easy to use, and very good for people who don't have much experience in security.
This a very good product because every time there is an update it corrects any issues. It can help an enterprise go up.
I would rate it a nine out of ten.

Manager Cyber Security at Dept. of the Premier and Cabinet
Good endpoint detection response, and technical support, but the pricing could be improved
Pros and Cons
- "Microsoft Defender for Endpoint is a robust platform."
- "In the next release, I would like to see better management reporting."
What is our primary use case?
We are a government organization, and we use Microsoft Defender for Endpoint Protection.
We also use it for vulnerability scanning and assessment, which is very useful.
What is most valuable?
Microsoft Defender for Endpoint is a robust platform. The endpoint detection response is quite good.
What needs improvement?
Some executive reporting is inefficient, and we're looking into ways to improve it.
In the next release, I would like to see better management reporting.
For how long have I used the solution?
I have been working with Microsoft Defender for Endpoint for two years.
What do I think about the stability of the solution?
Microsoft Defender for Endpoint is a stable solution.

Which solution did I use previously and why did I switch?
Previously, we didn't work with anything as sophisticated. We used a pretty old-style endpoint detection response.
How was the initial setup?
On new devices, the initial setup is quite easy, while some of the older devices had some issues unpicking the old EDR product that had nothing to do with Defender.
What's my experience with pricing, setup cost, and licensing?
Pricing can always be lower.
What other advice do I have?
To achieve the best results holistically, consider the total cost of ownership of the Microsoft suite of products.
I would rate Microsoft Defender for Endpoint a seven out of ten.
Disclosure: I am a real user, and this review is based on my own experience and opinions.

Provides malware and ransomware protection and scales easily
Pros and Cons
- "The most important and the most relevant features of Defender for Endpoint are the malware and ransomware protection."
- "I would like to see the next generation of the tool improved to work with other operating systems, like Linux."

It's used to protect endpoints and, for some customers, it is used to deploy Microsoft 365 suite features. Most of our clients are medium-sized businesses.
What is most valuable?
The most important and the most relevant features of Defender for Endpoint are the malware and ransomware protection.
What needs improvement?
I would like to see the next generation of the tool improved to work with other operating systems, like Linux.
For how long have I used the solution?
I have had about a year's worth of experience with Microsoft Defender for Endpoint. I am a subject matter expert for a Microsoft partner in Colombia. We develop portfolios and solutions for our customers that need Microsoft products in their infrastructure. My role deals with the architecture of solutions.
What do I think about the stability of the solution?

The setup depends on the customer, but it is generally simple.
What's my experience with pricing, setup cost, and licensing?
Some customers have the licensing of the suite and have all infrastructure prepared for the installation and deployment. But in some cases, when customers haven't deployed the solution and don't have licenses, it can be expensive to start from scratch.
What other advice do I have?
Customers haven't given us any feedback about difficulties with the solution. With its intelligence and tools over cloud infrastructure, it's a good product. We are developing some use cases and projects for customers with Microsoft Defender for Endpoint. It is good for us.

Integrates very well with all Windows workstations, works very well, and has good stability and scalability
Pros and Cons
- "It integrates very well with all Windows workstations or other Microsoft Endpoint products. It also works quite well. So far, I have not had any issue that hasn't been sorted out. It doesn't use too many resources, so you don't have to install different things."
- "Its price could be better."
What is our primary use case?
We replaced our antivirus with Microsoft Defender, and we are implementing three products. We have Microsoft Defender for Endpoint, which is deployed on all our endpoints. We also have Microsoft Defender for Office, which works very well to protect Office documents.
We are using this solution for MDM and MAM for the endpoints. We are using its latest version.
What is most valuable?
It integrates very well with all Windows workstations or other Microsoft Endpoint products. It also works quite well. So far, I have not had any issue that hasn't been sorted out.
It doesn't use too many resources, so you don't have to install different things.
What needs improvement?
Its price could be better.
For how long have I used the solution?
We have been using it for three months.
What do I think about the stability of the solution?
It is very stable for Windows.
What do I think about the scalability of the solution?
It has very good scalability. We have 151 users.
How are customer service and technical support?
I have not directly interacted with them. My colleagues have interacted with them.
Which solution did I use previously and why did I switch?
We were using another solution that was number three in the market according to Gartner 2019.
How was the initial setup?
There wasn't really much that we had to do because we have Intune, so it was very easy to deploy. We used the Control Panel, and it was deployed on the rest of the machines. What took longer was the onboarding of the machines to Intune, but once they were there, they were all protected. We, of course, had to remove the old antivirus.
What about the implementation team?
We used a partner. We had two people for this.
What's my experience with pricing, setup cost, and licensing?
It is within the same range as other products. It is not too expensive, and it is also not cheap. Its price can be better, but, well, it is Microsoft.
What other advice do I have?
I would recommend this solution to others. I have a lot of good things to say about it. We are still navigating through it, and it has been working very well. We will absolutely keep on using it.
I would rate Microsoft Defender for Endpoint an eight out of ten.

Director, IT at a financial services firm with 201-500 employees
Flexible, well-integrated with Microsoft products, and the security profile it provides is insightful
Pros and Cons
- "The most valuable features are that it is flexible, and it is integrated with Microsoft products."

What is our primary use case?
We have this security solution activated on 10 different Windows PCs, and we have it for Office 365 products as well.
What is most valuable?
The most valuable features are that it is flexible, and it is integrated with Microsoft products. That gives us peace of mind.
I like the security center, as well as the full picture of our security profile and insights.
What needs improvement?
I would like to have additional features such as DNS lookup, which would help for detecting malicious sites. This is a key part that I would like to have, and other products already have it implemented.

What about the implementation team?
We deployed with our in-house team. We have two people, not full-time, who take care of deployment and maintenance. They are engineers.
