Overall, I would evaluate the Microsoft support level that I receive at probably about a seven, but that depends on the day. It has been spotty. We have had issues where the urgency level of the Microsoft support is not as high as ours, especially during a data breach or potential data breach situation. We have had issues with some of the offshore support being lackluster. One specific thing that comes to mind is we were on a support call with our CISO on the call, and the Microsoft agent, who did not actually work for Microsoft, is one of the vendors that Microsoft uses for support, said, "Just to set expectations, my lunch break is in an hour and I am going to go away then." For us, it was already ten o'clock at night and we had been working on this for a couple of hours, trying to get a security engineer on with us. For him to tell us that he was going to go away and have lunch, it was, "Okay, but go find somebody else if you need to." It was just the lackluster approach, and it seemed like he did not really care. We seem to get a lot of this when we get non-Microsoft support. I can identify areas for improvement with Microsoft Defender for Endpoint, as it is kind of a convoluted mess to try to take care of false positives. Especially when they have been identified as false positives but they keep going off over and over again. It is great for my pocketbook because it generates a lot of on-call action, but I would really prefer more sleep at two o'clock in the morning than dealing with false positives. I would say that the unified portal for managing Microsoft Defender for Endpoint is suitable for both teams as they are all in there. It would be great if they would stop moving things around and renaming things, which makes sense. The new XDR portal is pretty nice. Being able to have it central again inside of the regular Security Center without having to open up two windows is helpful. Overall, I think it is pretty good. There is always going to be something that could be improved, such as alerting and the ability to modify alerts would be a little bit helpful to have. Being able to add more data into the alerts and turn off alerts that are not as useful would be beneficial. It is hard to say what the quantitative impact the security exposure management feature has had on our company's security, because a lot of it is kind of subjective. I think we are sitting at around a fifty percent score still, and a lot of it is just kind of unusual circumstances that we cannot really implement without breaking the organization.

I use the Zscaler speed test, and it is very nice. We use some logs from Zscaler Client Connector to collect data and see what is happening, such as if there is an interruption or something. There is a specific tunnel version that we have to use because, depending on the internet provider, some of them have lower speed, so we have some issues. This is because of the provider, not from Zscaler. We use Office 365 services and Office applications, and because some connections are slow and they do not have full coverage from the internet provider, we have some issues. If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down. This may be because they put some policy. Of course, if you use Office 365 services such as Outlook, the minimum bandwidth is 5 megabits and more, so this causes issues if the users do not have a good remote connection. This depends on the companies and the users, so they need to fix it. This is not from us or our company. It is very useful, and the logs are very helpful. When we go to logs, we understand what is happening.

Quotes from Members

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

Pros

"Microsoft Defender is always running. It is doing its job, so it is fine. I don't have any issues with the way it was implemented or how we are running it. We have been upgrading IT throughout the years, but there have been no issues."
"The patch management is very easy, as it can be done automatically or added to a schedule."
"It's not really visible for the user - which is a benefit."
"Defender for Endpoint has significantly reduced our SOC team's workload by automating threat detection and response, allowing them to focus on other critical projects."
"It's really stable. I've used a lot of stuff, a lot of products, like ESET and Kaspersky. None of them are comparable with this one. This one is much better."
"The most likable feature of Microsoft Defender for Endpoint is the sheer number of features and data it provides."
"There are a couple of features, such as isolating the devices or connecting the device and connecting live response."
"Because it has been integrated with the OS, we get the entire software inventories, and we even get access to the registries. Those are the primary features."
"I'd rate the solution nine out of ten."
"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."
"Zscaler Client Connector is quite scalable, and I would rate its scalability as nine or ten out of ten."
"The real-time analytics feature in Zscaler Client Connector is another valuable feature called Digital Experience, or ZDX, which can easily identify the root cause of issues accessing public or internal resources and provide good analysis so relevant teams can quickly resolve them, making it a very good tool that helps customers."
"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."
"The best features of Zscaler Client Connector are that it gives the client a much more transparent experience, as they don't have to worry about connecting to a VPN."
"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."
"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."
 

Cons

"Microsoft Defender could be improved with features more like the McAfee ePO. It would be better if I had a console to get all the information for my endpoints. Maybe this is too much for it, but it would be better if it could handle those non-signature-based malicious codes or viruses."
"I would like to see fewer pop messages and alerts."
"Microsoft should improve support for third-party platforms, because not all functionality is available for all of them. It's a good product, but they should just extend the functionality for all platforms."
"I would just like them to have more consistency, and that's a comment that's across the board with Microsoft. They change things a lot."
"Microsoft Defender for Endpoint can use more advertising to promote their features."
"Microsoft Defender for Endpoint could improve by adding more security features."
"Defender for Endpoint is complex, and the documentation is detailed. At the same time, it's hard to navigate sometimes."
"There is some functionality that is not quite there yet."
"There is a hard learning curve for Zscaler Client Connector; their support isn't the greatest all the time."
"The stability of Zscaler Client Connector needs improvement, as it often disconnects and reconnects."
"Zscaler Client Connector is not low in cost; it is definitely on the higher side."
"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."
"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."
"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."
"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."
"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."
 

Pricing and Cost Advice

"Most people don't realize M365/E5 licenses are an amazing deal. They think "Oh, it's expensive," and I'll ask, "Compared to what?" If you don't have it you will have to buy licenses for multiple products to fill the same security space that you would have gotten with the Microsoft product. Go figure out how much it costs you per product, per user, and then come back and tell me how things add up financially."
"There are different licenses, such as E3 and E5."
"The price was a problem for me three years ago, but they improved their E3, E5, and a la carte licensing. In other words, you have to get all of E5. That used to be a problem because you had E3, Defender, and guardrails, but you needed an E5 license to get the management suite and the analytics. It's more flexible now. You can switch from a la carte to the entire suite when it starts to make sense. It's becoming more economically competitive to go that route."
"It is free. It is included in Windows 10."
"This solution is part of Windows and comes included with it."
"The solution comes as part of Microsoft Windows."
"The base price for an E5 license, which includes Enterprise Mobility + Security E5, is $57 per user per month."
"Microsoft Defender for Endpoint is included with a Microsoft E5 license."
