Robert Arbuckle - PeerSpot reviewer
Security Analyst III at a healthcare company with 10,001+ employees
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.

Has struggled with poor documentation and limited tuning options but supports basic protection needs
The major limitation of this product is that their documentation is very poor; their documentation is extremely poor. Their support is very poor for this product, and the solution is average. To be honest, it's not that effective. Their Threat Scan Engine has features that don't work properly; they have features that really don't work properly. Their solution provides writing style verification, but this solution comes with false positives 60% of the time. There is no way from their portal to fix it; you can either turn it off or turn it on. The solution has many bugs. I will recommend Microsoft first for replacing Trend Micro ScanMail, then Barracuda, but the problem with Barracuda is that for impersonation solutions, it doesn't work well. There are many features, but you cannot tune the product. Being able to tune a product is really important; such as adjusting settings to be aggressive, minimal, or to exclude certain things. These are the most important considerations when purchasing a product. When impersonation is needed, but there are false positives, there should be an option to tune the product. Barracuda and Trend Micro Deep Security lack this feature, which is pathetic.

Quotes from Members

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

Pros

"It's free. There is no additional cost. It's part of Windows."
"User-friendly, offering safety and security."
"We have just started to implement it. It is useful for protection from malware and ransomware."
"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."
"The most important and the most relevant features of Defender for Endpoint are the malware and ransomware protection."
"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."
"We use Microsoft Defender for the antivirus."
"The solution has good performance, I have not seen a problem."
"The most effective feature of ScanMail is its real-time antivirus behaviors, particularly when it scans URLs."
"It does the job. Even when our clients have a very high rate of emails per second, there has been no problem."
"I find Trend Micro ScanMail to be a stable solution, and I would rate its stability as nine out of ten."
"What I like the most about Trend Micro ScanMail is its easiness."
"The most effective feature of ScanMail is its real-time antivirus behaviors, particularly when it scans URLs."
"Its integration with mail platforms is valuable."
"I like that Trend Micro ScanMail is very effective and quite strong."
"The analysis part is good."
 

Cons

"The frequency of the patching, and the frequency of the updates, are not included with the free version."
"We would like to see more tools for managing on-premises security... Sometimes, we have the tools, like Defender, to manage security in the cloud, but because we are so focused on the cloud, we forget the fact that we need to be sure about the security of the on-premises environment, specifically Active Directory."
"They're in the process of pulling more things together. They can continue with the integrations and provide a better way of seeing the impact of security changes, especially on the endpoint side. Before we actually flip the switch, we should be able to see the impact of security changes on the business or business applications. It would prevent breaking any business applications."
"We'd like to see integrations with more vulnerability scanning solutions like Tenable."
"The management console is something that can be improved."
"Additional security would be beneficial."
"I think Microsoft Defender for Endpoint is a solution which needs a little bit more resources on the CPU side, as we detected that on some virtual machines in Azure, with the activation of Defender, the CPU utilization increases about ten percent."
"Integrating this with third-party systems has some complexity involved."
"ScanMail needs improvement in its reporting, as it is currently weak in some areas."
"The price could be better. I think it's pretty good compared to other solutions as far as the features are concerned. It basically covers most of the stuff which we require for email security. But it would be better if they made it a little cheaper and more cost-effective. That would make it easier for us to sell it."
"I believe there is room for improvement in better signatures, better reporting features, and more insight into the spam emails database."
"The sandboxing part can be improved."
"The weaknesses of Trend Micro ScanMail are that it doesn't fully protect ad-based web access and lacks proper security for Outlook, iOS, and web browser access."
"Even Trend Micro ScanMail support staff are not familiar with this product."
"Its user interface is pretty old-fashioned, and sometimes, it's hard to find the features that you are looking for. The user interface definitely needs some improvement."
"ScanMail needs improvement in its reporting, as it is currently weak in some areas."
 

Pricing and Cost Advice

"Currently, for us, Windows Defender is free with the purchase of Windows Server. Pricing is an important point for us when we are looking at the competitors of this solution. If we choose to go with another vendor, we will have to pay some license fees."
"It isn't cheap, but it's reasonable and fair."
"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."
"It is free."
"The solutions price could be cheaper."
"This solution is part of an enterprise license we have."
"Microsoft Defender for Endpoint is an expensive solution."
"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."
"It is an expensive solution. I rate the pricing a seven out of ten."
"Its price is okay. It is not too high."
"It's a yearly subscription, but the price could be better."
