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.

Immediate results in patching promptly address vulnerabilities
When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task. It would be easier if Tanium provided the patches directly. Some other brands provide the patch with a direct download link, which facilitates the process. Also, I feel that if there were more detailed documents and remediations readily available online for troubleshooting, especially more up-to-date information, it would be beneficial. Currently, some resources online are very out-of-date.

Quotes from Members

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

Pros

"The feature I find most valuable in Microsoft Defender for Endpoint is that it blocks the process and keeps the endpoint from getting infected with malware."
"Microsoft Defender for Endpoint comes pre-installed in Microsoft Windows."
"Stable endpoint manager, antivirus, and antimalware, with fast technical support and a straightforward setup."
"It does not make Windows slow, as compared to all of the third part antiviruses."
"We have liked the fact that it comes with Microsoft Windows 10 and it is constantly updated with all new virus definitions. It is also updated with new security features on a regular basis."
"I enjoy using the live response feature, which allows me to remotely access different endpoints and investigate malicious files, such as malware that people may have downloaded, and other related issues."
"Microsoft's technical support is fantastic."
"The detection features are valuable, as is the fact that it is easier to port these logs into Sentinel. That is also useful for us. It is more comprehensive."
"The product is granular and can build complex roles compared to other EDR vendors."
"The interrogation piece was the most valuable feature because it was very detailed."
"Tanium is a very good product and I would rate it eight or nine out of ten."
"I would say Tanium is the best tool for vulnerability management."
"Tanium has made the process of detecting threats more proactive with its detection. So, the process is easier and more efficient."
"Threat hunting is a very good feature on Tanium. We have just started using it and have not used it extensively."
"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."
"Tanium's most valuable feature is its instant discovery aspect."
 

Cons

"The file scanning has room for improvement. Many people use macros within their files, so there should be a mechanism that helps us to scan them for malicious payloads."
"I would like MDE to have the ability to isolate a certain amount of time on the timeline."
"The initial setup can be a bit complex."
"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."
"The solution needs to improve its ransomware. It's not so good. It could also use some general performance optimization for the computers the solution operates on, to ensure it does not slow down the devices."
"Updates are not coming out of preview quickly enough and it is holding back on the development of the product."
"I personally haven't experienced any pain points, but some of my coworkers feel that it isn't secure enough."
"This solution is not secure, which is why I have moved to Linux."
"The solution needs to improve the reporting and tracking capabilities."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"Any movement into a SaaS solution has challenges since the processes and data flows are not well defined. Hence, you need to build it at the same time."
"The main issues are the network connection because different customers have issues with their networks. It's difficult implementing this type of solution because the network is the main feature in the architecture for these types of solutions. Tanium could improve by creating some network optimization."
"When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task."
"When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium."
"Most of the time, agent-relative issues have to be more equipped with self-healing features. At times, the agent is there, but for some reason, it doesn't report a status. It gives certain problems that are obviously agent-based."
"It is not really additional functions, or the features that are needed, rather the complexity would be reduced based on the number of modules required to put together a comprehensive operational security and risk compliance model."
 

Pricing and Cost Advice

"Compared to ESET, the pricing for Microsoft Defender for Endpoint is on the higher side."
"Microsoft Defender for Endpoint comes with Windows 10, and it's free. But for you to be able to manage it in the cloud and use the console, you need to have either an Office 365 E5 subscription or a Microsoft M365 subscription. You need to buy an extra license."
"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."
"I pay for it through the Windows Professional or Standard license. It is a one-time cost for me, and I use the same license."
"The base price for an E5 license, which includes Enterprise Mobility + Security E5, is $57 per user per month."
"Everybody would like to see a lower price on everything. The Slovenian market is basically an SME market with clients having up to 100 seat licenses, comprising 90% of the company. They're very price sensitive. So, the price could be cheaper."
"This solution is part of Windows and comes included with it."
"It is an expensive solution. It would be nice if it could be included with the Microsoft Office package."
"There is an annual license required to use this solution."
"It's an expensive solution. It would be nice if the cost were lower."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"It is higher than some competitors in the market."
"The solution is expensive but it's a good investment."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"The solution offers value for money."
