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.

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.

Provides strong email filtering and threat intelligence but pricing needs improvement
I work with SonicWall Email Security SonicWall Email Security uses multi-layer cloud security. It filters emails before they come to my provider, such as Office 365. It has real-time threat intelligence and provides strong data loss prevention. Additionally, it filters emails before they reach my…

Quotes from Members

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

Pros

"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Defender helps us prioritize threats across our organization."

"It’s easy to handle integrations, and we don't need a lot of people in our IT team."

"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."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."
"The archiving and search features are very good."
"The most valuable features of Barracuda Email Protection are flexibility and customization."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"When we got the service, it included the email archiver with unlimited storage."
"The most valuable features are security and ease of use."
"The most valuable aspect includes attempts to spoof or compromise domains from external sources."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
"According to our customers, the product's most valuable feature is the ability to detect spam and reduce phishing emails."
"The product is easy to manage in terms of configurations."
"It is a very scalable solution."
"The most valuable feature is that it protects from spam."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"SonicWall Email Security uses multi-layer cloud security."
"Setup was easy. It took about 30 minutes."
 

Cons

"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"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."
"We need to be able to whitelist data at the backend."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"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."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"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."
"I would like to see better integration with other products."
"The platform's pricing needs improvement."
"I would like to see some additional functionality in terms of employee monitoring, as part of a work-from-home security solution."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"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."
"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."
"There could be definition updates included in the subscription."
"A lot of spoofed emails are still coming to the end-user, so the configuration for this option needs to be improved."
"The pricing could be improved."
"They should integrate the solution with third-party platforms."
"The technical support from the company is not always very good at solving issues, but they offer access to a good community of users where problems are easily solved."
"The reporting needs improvement."
"The platform's control panel needs enhancement."
"The pricing could be improved."
 

Pricing and Cost Advice

"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"I was working in the government and it was too expensive for us to use our Microsoft products."

"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"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."
"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."
"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 solution's pricing is moderate, where it is neither cheap nor expensive."
"Our customers purchase the solution's yearly license."
"We have a two-year license subscription and the price is very high."
"When compared with Cisco, it is very well priced. Cisco is very expensive."
"The overall price of SonicWall Email Security should be reduced and there should be an option to purchase one or two licenses more instead of their current policy of bulk increases only. There should be more flexibility in the licensing model. Each license cost approximately $33 annually."
"I rate the application’s pricing a five out of ten."
