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

"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"Defender helps us prioritize threats across our organization."
"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."
"Armorblox is a scalable solution."
"We now have a secondary backup of Office 365 that's much easier to retrieve compared to Microsoft. If someone deletes something in Office 365, we can get it back within Office 365, but it's difficult. Barracuda is much easier. There is a lot less management needed using Barracuda. The management becomes much easier for Office 365 and it's no longer on-prem, so there are fewer hours managing on-prem devices, servers, and things of that nature. We don't have network appliances anymore for the backup of our information."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"I would rate the solution nine out of ten."
"The archiving and search features are very good."
"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."
"The product is easy to deploy and maintain."
"The most valuable features of Barracuda Email Protection are flexibility and customization."
"The most valuable features are security and ease of use."
 

Cons

"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"The product must provide better malware detection."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"The phishing and spam filters could use some improvement."
"We need to be able to whitelist data at the backend."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"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."
"Armorblox lagged in terms of grabbing phishing emails or phishing campaigns."
"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."
"The platform's pricing needs improvement."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"Barracuda Essentials can improve by continually adding more features."
"I would like to see better integration with other products."
"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 product must enable bulk user management."
"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."
 

Pricing and Cost Advice

"I was working in the government and it was too expensive for us to use our Microsoft products."
"The pricing has become expensive."
"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."
"The license is expensive because the cost is based on the number of users."
"I know that the product is incredibly expensive."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"The product is very expensive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"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."
"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."
"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."
"The price is similar to that of Microsoft 365."
"Barracuda licensing model is good."
"The solution's pricing is moderate, where it is neither cheap nor expensive."
"The product is expensive."
"The price of Barracuda Essentials is better than some of the competing products."
