A highly scalable and easy-to-learn product that blocks phishing and spam emails
The product must improve the features associated with creating a blacklist. Currently, to add a content block, I have to go to a different screen. It seems cumbersome. The solution sells Impersonation as a separate product. I don’t see why it cannot be in the same product like other vendors have.

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.

Quotes from Members

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

Pros

"The most valuable feature of Barracuda Email Threat Scanner is the security it provides by delaying the delivery of suspicious emails until they can be reviewed inside the Barracuda control panel."
"The main benefit that I am getting from this solution is that it filters almost 95% of my spam mail. Some spam mails bypass Barracuda Email Threat Scanner, but when I add those domains or addresses to the filter list, they get blocked. Some users on my premises do not understand which mail attachments or links should be opened. By filtering with Barracuda Email Threat Scanner, we are not getting any type of phishing mails. So, our infrastructure is safer, and as an IT person, I feel relaxed."
"It was easy to learn the product."
"The notification and reporting features are most valuable because we are part of a compliance project, and maintaining SOC 2 compliance is critical."
"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."
"It is already integrated with Windows 10, so you don't need to worry about that."
"I've started to test it from the security point of view. There are plenty of features that are interesting, but at this time, the XDR functionality is most valuable. It is endpoint security on steroids."
"Web filtering is the most valuable feature of Microsoft Defender for Endpoint because it effectively maintains security for website access."
"The most valuable aspect lies in its automation capabilities, particularly within security automation."
"Technical support is good."
"I like Defender's reporting and logging features. The email alerts are also helpful. It's hard sometimes to sift through the email, especially if you're an IT firm managing hundreds if not thousands of endpoints, but we find email reporting useful. For example, last Tuesday, we learned of new vulnerabilities that were discovered as a result of the previous patches. The endpoints without those patches triggered alerts in Defender."

Cons

"The product must improve the features associated with creating a blacklist."
"If the price were lower, perhaps we could purchase our own."
"We had an incident last month where the PCs of one or two colleagues, who were outside of our factory and were using a defined network, got infected by some kind of malware. From their PCs, more than 1,000 mails were produced per hour, causing spamming on our mail server. Barracuda blocked the full mail communication. Only one to two accounts were compromised, and for that, Barracuda blocked all incoming and outgoing mails. It created a great problem for other users and our office activities. Our server was blocked for three days, which we did not expect. Technically, only one or two accounts should be blocked. When a domain or IP is blocked, communication becomes tough. It may be a configuration issue at our provider's end, where there was a mistake in configuring Barracuda. It could also be a problem related to Barracuda."
"Features like device inventory continue to lack essential workstation drill-downs showing the entire device information with the least effort."
"Microsoft Defender for Endpoint could provide us with a more holistic approach, such as collaboration. They can provide us with an environment from where we can manage all the endpoints from one central location, such as overall management."
"There are some areas in the proactive threats that are just overwhelming the SOC, so we've had to turn those off until we can figure out how to filter out the false positives."
"If they integrate with the EDR then it will benefit this solution."
"There is a need for improvement in reducing false positives."
"It is not very scalable from the eyes of an MSP because there is no dashboard that you can use to see all of your devices that have Windows Defender unless you have your own dashboard or an RMM tool to actually look at it. So, you might not get to know that a particular computer of a client is doing something, and it might have got a virus. That person might know that, but unless you set it up to actually send you the information, you won't get to know that. That's one of the things that is hard with Microsoft Defender. It is not made for the MSP world where you have one pane of glass to see all of your clients with Microsoft Defender on it unless your RMM tool already has that built-in and it can see the telemetry from Microsoft Defender."
"I am not sure if I will be using this product in the future because of the price."
"Lacks some additional integration."

Pricing and Cost Advice

"The solution is a bit expensive."
"Barracuda Email Threat Scanner is provided by our IT service provider, who also provides all the support. The licensing fee that we pay to our provider is $200 per month, that is, $1 per user. There is no additional cost. Before taking the subscription from our provider, I researched the market for Barracuda. The cost is between $5,000 to $8,000 for three years. After that, the same cost is there for renewal. If you have 200 to 500 users, it is better to take a subscription from a provider. If you have more than 500 users, then you can own the Barracuda server through the cloud or on-premises deployments. It is costly for a lesser number of users. If you increase the usage or the number of users, then the overall cost decreases. They can reduce the cost of Barracuda Email Threat Scanner for a small number of users. We could not and would not have used this solution if we had not got the renting or subscription option."
"AV solutions are pretty expensive because they are necessary, not just for protection, but many businesses need them to comply with regulatory bodies and receive accreditation. We recently purchased an E5 license, which gives us access to the entire Microsoft suite. I would say the pricing is competitive; most tools of this kind are similarly priced. There are minor differences between the competitors, but they aren't spectacularly different. Defender for Endpoint makes sense because all our solutions are in the same place, paid for with a single license. The subscription price is around £50 per user per month, though it may have increased slightly."
"Microsoft Defender is an expensive product in my country."
"Its price at the moment is very good because you get a lot of value for your money, especially with the subscriptions. If you have the E1, E3, or E5 enterprise subscription, you pay per month per user, and you get almost an infinite number of solutions. If you compare the price to the number of solutions that you get, it is a very good deal."
"The licensing fee is a function of your Office 365 license. The feature set you get is a function of the license as well. There is probably an E2 version, an E3 version, and an E5 version. There are several versions, and not all features are the same. So, you might want to check what features you're expecting because you might get shocked. If you only have an E3 license, the capability isn't the same."
"The solutions price could be cheaper."
"The product is free of charge and comes integrated into Windows."
"The cost is high for E5 licenses, but if we go with the E3 license, most of the features are not covered."
"It is free."
