Automatically isolates threats and integrates with logging to reduce response time
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.

Security suite has protected individual devices from threats, while installation and network features require improvements
BIG-IP is actually the LTM, Link Load Balancer, which comes with ASM, meaning Application Security Module. It consists of multiple modules, such as ASM, SWG, and a domain DNS manager. ZoneAlarm allows defining trusted and public networks, which helps maintain security in public Wi-Fi environments. It offers comprehensive protection, securing PCs against threats. Users do not experience any system slowdowns while scanning. Harmony Browser protects all your browsing activity and is bundled with Harmony Endpoint and Harmony Connect. It provides a small but effective security layer and sometimes comes packaged with the larger Harmony suite.

Quotes from Members

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

Pros

"Defender has very little impact on the end-user and the agent works quite well with a minimal impact on the client and server."
"What I like most is the protection against phishing emails and anti-spam."
"The most likable feature of Microsoft Defender for Endpoint is the sheer number of features and data it provides."
"I like the process visibility. This ability to visualize how something was executed is valuable, and the fact that Defender ATP is also linked to the threat intelligence that they have is also valuable. So, even if you have something that doesn't have a conventional signature, the fact that you get this strange execution means that you can detect things that are normally not visible."
"Microsoft Defender for Endpoint is easy to load and it runs quietly in the background, unlike other solutions."
"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 whole bundle of the product, which is similar to other Microsoft products, is valuable. Ten years ago, you had third-party stuff for different things. You had one solution for email archiving and another third-party one for something else. Nowadays, Microsoft Office covers all the stuff that was formerly covered by third-party solutions. It is the same with antivirus. The functionality is just basic. You have the scanning, and then you also have a kind of cloud-based protection and reporting about your environment. With Microsoft Security Center, you have a complete overview of your environment. You know the software inventory, and you have security recommendations. You can not only see that the antivirus is up to date; you can also see where are the vulnerabilities in your system. Microsoft Security Center tells you where you have old, deprecated software and what kind of CVEs are addressed. It's really cool stuff."
"The solution is highly scalable."
"The phone access scan stands out as the most valuable feature for me."
"ZoneAlarm protects all computers from viruses, spyware, and hackers."
"Personally, I find the Game Mode of the Firewall very useful."
"This antivirus is regularly updated, and the updates can be scheduled."
"The product's most valuable feature is the detection engine due to its ability to identify threats."
"The solution maintains reasonable scalability."
"It is easy to use through interfaces and easy to configure each of the customizations we created based on the characteristics that we wanted."
"It gives us security for the users' mobiles and ends up protecting us in a significant way."
 

Cons

"It can get a bit laggy sometimes. Other than that, we don't have any issues. They constantly tweak it and fix it up based on users' feedback. It has improved a lot over the past four years. Defender for Endpoint never really used to be a good endpoint security solution, but over the past couple of years, Microsoft has invested heavily in it. So, it has come a long way in all aspects of endpoint security. If they want to make it better, they should just continue investing in the current path of what they've been doing over the past couple of years."
"Defender is free for one year. Once that year is over, we will switch to Kaspersky."
"We'd like the stability to be better."
"I would like the solution to be able to prevent unauthorized programs from installing and to block unauthorised URLs which is similar to web filtering product."
"I don't think it's scalable at this moment. It is doing what it's supposed to do, but Microsoft Defender for Endpoint isn't there yet."
"Microsoft Defender for Endpoint is not as robust, and you cannot customize it much, so that's a challenge."
"This solution is not secure, which is why I have moved to Linux."
"The documentation could be better. When they update their manuals, sometimes they refer to products by their old names, so it is a little confusing. For example, the documentation might still say "Advanced Threat Protection" instead of Defender for Endpoint."
"They should release a single update with all the necessary characteristics to avoid being in a cycle of consecutive updates."
"ZoneAlarm should be a light application that does not take too much memory in mobile phones."
"Currently, the client is only available for the Windows Operating System but it would be good if it were released for Mac OS as well."
"They need to update and improve the features available for Mac."
"Some of our users say that the interface is a little bit outdated for 2020, and want it to be more modern and cozy."
"Perhaps the primary area for potential enhancement is to make it faster, ensuring a more seamless experience while maintaining robust security features."
"I would like it to be integrated with the Check Point centralization solution like Infinity Portal. It would be great to be able to manage it through the same website."
"We'd like better performance of the network equipment. There are high-speed environments where an immediate response is required."
 

Pricing and Cost Advice

"The price for Microsoft Defender for Endpoint is about three euros, which is considered reasonably priced."
"Defender doesn't cost that much. When you use Microsoft technology, you can start with the free version and see how much the technology helps your organization solve security problems before you use the subscription. They also do this pay-as-you-go model, so you only pay when you use it."
"This is an expensive product and licensing for all Microsoft products is a big issue."
"For me, the pricing is very good, but for management it's very expensive. Other solutions are less expensive. But when I present all the information and all the reports they say, "Well, it's expensive, but the cost-benefit is very good.""
"I'm not too familiar with costs as I'm an architect, though I know about online pricing, as I help two teams with online purchasing and procurement. Nowadays, everyone has an enterprise agreement, such as an E3 license, which we provide to our customers."
"Because Microsoft Defender comes as an add-on, it can be a bit expensive if you're trying to buying it separately. Another option is to upgrade, but the enterprise licenses for Microsoft can also be quite a bit pricey. Overall, the cost of Microsoft Defender compared to that of other endpoint detection solutions is slightly higher."
"This product is included in the pricing for Windows."
"We have an enterprise agreement so from my perspective, this is a product that ships with Windows and it is not priced standalone."
"This is a freeware product and I recommend using it."
"We have to pay a yearly licensing fee for ZoneAlarm, which is cheap."
"The pricing is reasonable, with a yearly renewal license costing seventy dollars."
"I rate the product pricing a seven out of ten."
"We use the free version of the software, but it can be upgraded to the paid Extreme Security edition."
