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

"This is not an inventory solution, but it helps you take count of how many workstations you have, as well as what software is installed on each of them."
"The solution integrates very well with Windows applications and Microsoft endpoint products."
"The most valuable feature is ransomware protection, which can detect malicious activity from IPs or a malicious payload in DLLs, or other things that can corrupt the system."
"It's great for investigating what's happening on a machine. They show a whole bunch of machine timeline events that are related to a security incident. They have quite good details on the things related to threat and vulnerability management, such as any weakness that has been disclosed publicly, assets that are exposed, and if there is an exploit active in the wild for that vulnerability. It can provide you with all such information, which is cool."
"Microsoft Defender for Endpoint is extremely stable."
"It is a very advanced system based on AI. It has a very large database of places or sites on the internet where you should not go. It is continuously online."
"One of the valuable features of the solution is the small updates that keep my machine relatively clean from any infections."
"Endpoint's most valuable feature is deep analysis."
"It is easy to use through interfaces and easy to configure each of the customizations we created based on the characteristics that we wanted."
"The phone access scan stands out as the most valuable feature for me."
"This antivirus is regularly updated, and the updates can be scheduled."
"Personally, I find the Game Mode of the Firewall very useful."
"The solution maintains reasonable scalability."
"The product's most valuable feature is the detection engine due to its ability to identify threats."
"It gives us security for the users' mobiles and ends up protecting us in a significant way."
"ZoneAlarm protects all computers from viruses, spyware, and hackers."
 

Cons

"This solution needs to move beyond relying on virus definitions alone and protect the system using behavioral analysis of the processes that are running."
"The actual product updates have caused a little bit of disruption that could be avoided, so I think that customers need to have more granular controls as to when updates can be deployed versus more done from a top-down deployment perspective."
"From an audit point of view, our auditors would like to have more reports on how things are used, if things go wrong, and how they went wrong. For example, if something got a warning, "Why?" So, we would like more versatility for tracing and reporting. That would improve the product, as long as the user interface doesn't get bogged down."
"Defender could be more secure and stable."
"The scalability could be improved - I would rate it between a seven and an eight."
"Defender's cloud integration could be improved."
"Updates are not coming out of preview quickly enough and it is holding back on the development of the product."
"In terms of the architecture of the management infrastructure, we found that other technologies are more simple. Microsoft Defender could be simpler too."
"Perhaps the primary area for potential enhancement is to make it faster, ensuring a more seamless experience while maintaining robust security features."
"They need to update and improve the features available for Mac."
"ZoneAlarm should be a light application that does not take too much memory in mobile phones."
"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."
"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."
"Some of our users say that the interface is a little bit outdated for 2020, and want it to be more modern and cozy."
"The solution's efficiency in threat containment and overall protection needs improvement."
"We'd like better performance of the network equipment. There are high-speed environments where an immediate response is required."
