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.

Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

Email security offers superior protection with good personalization
I have experienced the Barracuda team as very cooperative, and they are readily available for calls with technical support via email. I have had no issues with ongoing support throughout the product's lifecycle. Assistance was provided to me when transferring archived information from a legacy email service. They also recommended an additional service to streamline the process, making it as easy as possible.

Quotes from Members

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

Pros

"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Does a thorough job of examining email and URLs for malicious content."
"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."
"The DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"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 ability to respond to threats if very important."
"The stability of Microsoft Defender for Office 365 is fantastic."
"The email protection is excellent, especially in terms of anti-phishing policies."
"If we look at four to five years ago, we had close to six or eight people click a link in an email per month. Now, we are probably down to about five or six clicks a year, if not less."
"It is simple to deploy this platform and interact with the set features."
"I like Avanan's SmartDLP module. It's seamless, and the administrative overhead is low. We aren't a very sophisticated operation. We just want to reduce our exposure, so we find ThreatCloud helpful. Avanan's acquisition by Check Point was beneficial for them."
"It can detect corrupted files and filters out documents with viruses."
"The most valuable feature of Avanan is its Anti-Malware solution for Office 365, and box.com."
"The most valuable feature of Avanan is its effectiveness. When scanning incoming emails for threats it can in an automated fashion, quarantine suspicious attachments."
"It can retract unsafe emails and remove them from the entire communication channel."
"Spam protection is the most valuable feature."
"We find the product to be scalable."
"Great at blocking spam."
"It is very simple to whitelist addresses."
"The solution helps us to block some blacklisted emails."
"Customer support is the solution's strongest point."
"The spam filtering, in particular, is very important for us. We have a large volume of emails each month, something like 200,000, and Barracuda filters about 85 percent of the spam, malware, and phishing that comes in. It prevents our users from receiving this content on their computers."
"Thanks to Barracuda Email Security Gateway, I have seen increases in productivity and functionality in terms of spam reduction and filtering against different threats, which is a benefit by default."
"Barracuda Email Security Gateway has features like identify the spam source, rules to avoid some specific spams and then reschedule. And there are some other features like the email continuity, the email server and gateway site, which can relay the mail kit. The solution is user-friendly.These kind of features are the most valuable."
 

Cons

"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The product must provide better malware detection."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"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."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"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."
"When sending bulky emails, the system slows down and takes a long time before it responds effectively to our requests."
"They should come up with a mobile application so that it can be more flexible."
"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"Avanan doesn't cover certain tool segments."
"There are times when we have false positives."
"The user experience must be improved."
"The customer service team could come up with clear tutorials on how to use this platform to help new teams."
"Integration with various SaaS offerings, who are leading in the SaaS market."
"There are limited administration controls that should be improved."
"We would like to have a local support center in India so that they are operating in the same time zone and speak the same language."
"My customers were sending OPT bulk emails and Barracuda Email Security Gateway was not able to handle it. We have to go with another different solution, such FortiMail for the task. We are implementing these combinations of the Barracuda and FortiGate, for email security. The FortiGate FortiMail security gateway we use to send only the bulk email, not for receiving emails."
"The pricing needs improvement."
"Sometimes there are false positive emails coming through, so they should improve further on detection technologies and techniques."
"The scalability needs improvement, it's the only feature that is required."
"Some of the phishing emails are not being blocked. Another problem is that we are not able to manage the date and time in our time zone."
"I would like to have better integration with third-party archival vendors to facilitate moving data in and out."
 

Pricing and Cost Advice

"The license is expensive because the cost is based on the number of users."
"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."
"The pricing is normal. Considering its popularity, it's not overpriced."
"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."
"It's a user-base subscription."
"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 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 product is not the cheapest in the market."
"Avanan’s price is comparable to Barracuda."
"The pricing of Avanan is reasonable."
"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does. They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."
"Good pricing arrangement as an SaaS offering."
"Barracuda Email Security Gateway is a cost-effective solution."
"Barracuda Email Security Gateway is an affordable solution that caters to small, midsize, and high-end businesses with great revenue."
"The solution requires a license and we pay annually."
"It is a cost-effective and relatively cheap solution as compared to others. Our customers have a yearly subscription. We do have a few customers with monthly subscriptions, but they have cloud-based Email protection, which is a different type of solution. Both solutions are very good."
"For overall value and cost, Barracuda came in as most appropriate, price as well as services provided. In terms of price, it's average . It's not the most expensive, it's not the least expensive but it works well."
"We paid for an annual license."
"The pricing for the product is fine."
"The licensing fees are part of a bundled support package that we pay for."
