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

"When we got the service, it included the email archiver with unlimited storage."
"The beauty of Barracuda Email Protection is that it is easy to manage and simple to deploy."
"The archiving and search features are very good."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"The most valuable aspect includes attempts to spoof or compromise domains from external sources."
"The solution's most valuable feature is impersonation detection."
"The product is easy to deploy and maintain."
"I'm quite satisfied with the graphical user interface for Barracuda products."
"Microsoft Defender for Office 365 is a stable solution."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"Scalability-wise, I do not think there are any issues so far."
"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."
"The technical support is good and quick to resolve issues."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
 

Cons

"There is room for improvement, particularly in reaching out to technical support during deployment."
"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."
"They could simplify the licensing and the pricing."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"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."
"I would like to see some additional functionality in terms of employee monitoring, as part of a work-from-home security solution."
"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."
"The platform's pricing needs improvement."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"The product must provide better malware detection."
"The pre-sales cost calculations could be more transparent."
"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."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"You should be able to deploy Defender for every subscription without the need to add servers."
 

Pricing and Cost Advice

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a seven out of ten."
"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."
"The solution's pricing is moderate, where it is neither cheap nor expensive."
"Price-wise, this product is middle-of-the-road."
"The price is similar to that of Microsoft 365."
"Barracuda licensing model is good."
"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."
"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The pricing has become expensive."
"I know that the product is incredibly expensive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"It's a user-base subscription."
"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."
