Featured Reviews

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.

Lags in terms of grabbing phishing emails or phishing campaigns, though it has good scalability
Armorblox is a cloud-based solution. The solution helped us improve the security, but we had a couple of issues regarding the operation. From an email security perspective, users or employees don't need gray mail or phishing emails in their email boxes. So, if the tool is not performing well in that area, then there's no sense in using that particular tool. Overall, I rate Armorblox a five out of ten.

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.

Quotes from Members

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

Pros

"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"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 ability to respond to threats if very important."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"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."
"Armorblox is a scalable solution."
"The most valuable aspect includes attempts to spoof or compromise domains from external sources."
"The product is easy to deploy and maintain."
"The archiving and search features are very good."
"I'm quite satisfied with the graphical user interface for Barracuda products."
"The solution's most valuable feature is impersonation detection."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."
"The most valuable features are security and ease of use."
 

Cons

"The XDR dashboard has room for improvement."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"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."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"Armorblox lagged in terms of grabbing phishing emails or phishing campaigns."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"There is room for improvement, particularly in reaching out to technical support during deployment."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"The policies are set up in Barracuda by default; we don't have any control over them."
"The solution's graphical user interface (GUI) could be improved visually."
"The product must enable bulk user management."
"I would like to see better integration with other products."
"The platform's pricing needs improvement."
 

Pricing and Cost Advice

"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The pricing has become expensive."
"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."
"The product is very expensive."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a five out of ten."
"Price-wise, this product is middle-of-the-road."
"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."
"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 of Barracuda Essentials is better than some of the competing products."
"The solution's pricing is moderate, where it is neither cheap nor expensive."
"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."
