Very good threat protection, spam filtering, and cloud backups
Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings. For instance, for email quarantine, I can't set up a global setting. Users must go through an induction session where I guide them in configuring quarantine alerts rather than having default settings based on group membership. This seems like an oversight since they already use Active Directory details. They should assign policies based on group membership, which configures these settings by default.
Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Quotes from Members

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

Pros

"I would rate the solution nine out of ten."
"The product is easy to deploy and maintain."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"The most valuable features of Barracuda Essentials are it's a trusted name and is rated very high on review sites. It blocks high percentages of spam and junk email and it's in the cloud. They have hardware appliances, but this is in the cloud. The solution is very effective at blocking malware and blocking spam and this is what we are looking for. There's not a whole lot of complexity, you want a solution that is very good at blocking out all of the unwanted emails."
"The most helpful aspect for me is the out-of-the-box configuration, which is fairly good."
"The solution is straightforward to set up."
"The solution's most valuable feature is impersonation detection."
"The most valuable features of Barracuda Email Protection are flexibility and customization."
"Microsoft Defender for Office 365 is a stable solution."
"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
 

Cons

"Barracuda Essentials can improve by continually adding more features."
"The policies are set up in Barracuda by default; we don't have any control over them."
"Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings."
"The solution's reporting mechanism is a little poor and could be improved."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"The customer service and support could be improved if the support were available directly in Europe. Currently, the support is often managed from India, so we sometimes need to wait due to the time zone difference. It would be quicker and better if the support were provided by European staff."
"They could simplify the licensing and the pricing."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"Several simulation options are available within 365, and the phishing simulation could be better."
"I'd like some additional features any product can give me to protect our environment in a better way."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"In the areas of improvement for Microsoft Defender for Office 365, the console is the biggest challenge for me."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
 

Pricing and Cost Advice

"The product is expensive."
"Price-wise, this product is middle-of-the-road."
"We pay annually. They never charged us for anything else. And they were quite a bit under that $20,000 mark. It was $19,074. And they've been pretty good about not skyrocketing the price or anything like that. It has gone up. It's gone up to $24,000 in 2020."
"Barracuda licensing model is good."
"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."
"The price is similar to that of Microsoft 365."
"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."
"The price of Barracuda Essentials is better than some of the competing products."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"I know that the product is incredibly expensive."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"It's a user-base subscription."
"The product is very expensive."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
