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

"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"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."
"Since we have started using the solution, there have been fewer compromises."
"The technical support is good and quick to resolve issues."
"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."
"The product is not resource-intensive."
"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 most valuable feature of Avanan is its effectiveness. When scanning incoming emails for threats it can in an automated fashion, quarantine suspicious attachments."
"The customizable rules allow you to change aspects."
"Easy to use for non-technical users."
"This technology is one of Check Point's acquisitions, and it is currently a powerful tool that provides all the protection that is not found in other tools."
"The threat detection tools enable us to ascertain malware and phishing messages across the email network infrastructure."
"Email inspection has saved many employees from spam attacks and viruses from unauthorized sources."
"It can retract unsafe emails and remove them from the entire communication channel."
"The program has reduced the dangers related to phishing, malware, ransomware, and other vulnerabilities."
"The intuitive management interface feature makes email security policies very easy to implement as it's all about features that need to be enabled or disabled."
"It is a really good product with a lot of features. It is responsive, updated, and modern. It is easy to use and has an easy interface for non-IT users. Its dashboard is also quite fine. It is also quite flexible and has an API at the backend."
"It can scale."
"With the cloud service, one of the nice things about Barracuda is the quarantine service. It gives the ability for our users to go in and check what has been quarantined, and then connect with our IT staff to release anything that should be fine so that we can test it before we release."
"Great at blocking spam."
"One advantage is its immediate deployment capability. So the fast speed to deploy is a big plus point."
"Barracuda Email Security Gateway has a good feature of email spooling, which acts as a first line of security."
"It not only tackles spam effectively but also incorporates advanced features like ATP and active features which ensures a comprehensive and adaptable email security solution tailored to their heterogeneous environment."
 

Cons

"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"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."
"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."
"The custom alerts have to improve a lot."
"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."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Configuration at the mid-level could be improved for the support team."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"The system response in a slow computing device affects performance when sending and receiving emails."
"When sending bulky emails, the system slows down and takes a long time before it responds effectively to our requests."
"Sometimes it seemed like the allow list wasn't working. I've created many allow list rules however, they still seem to be blocked; the same is true with the blocked list rules."
"Familiarization with performance for new teams may take a long time."
"It is very difficult to find the required documentation."
"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"Being cloud first and because we are in the movie business, we use a lot of Macintoshes. So, there is absolutely no reason for us to have Active Directory whatsoever. However, if you are using Office 365, you must have Active Directory in order to reset passwords. Even though we have a single sign-on provider, we must have Azure Active Directory for Office 365, which is really stupid. As a cloud application, you would think that I don't need Active Directory, which I don't need for anything else except Office 365. We have one server inside that space to help us manage Active Directory just for Office 365. This is a very sore point, but it is what it is."
"The customer service team could come up with clear tutorials on how to use this platform to help new teams."
"Barracuda Email Security Gateway can improve reporting and anti-spam. The anti-spam engine is not working well. We are seeing a lot of problems where spam is going through the gateway. Additionally, access privilege should be given to the IT support, because they don't have a lot of privileges. We are forced to give our IT support administrative access in order to clear and deliver emails and this should not be happening."
"Few customers require an on-premises fabric ATP box for attack detection and response."
"Two improvements that are needed include an enhancement in the proxy feature, as well as the ability to more fully automate patches and updates."
"We still have critical threats coming into our environment and delivered to our users. When we compare it with other solutions, these other solutions can already detect those threats."
"Barracuda isn't catching everything. We're still getting quite a few phishing emails, so we're looking for something else."
"Solution requires regular checking to ensure it's 'keeping up' with spam."
"There is room for improvement in the management of multiple domains."
"Barracuda could improve its log and export options like PDF and HDML. It can also bring in more detailing in their console so that it could be better. Some new features should be expanded and made accessible for better protection."
 

Pricing and Cost Advice

"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The product is expensive."
"The pricing has become expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."

"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."
"Avanan’s price is comparable to Barracuda."
"The product is not the cheapest in the market."
"Good pricing arrangement as an SaaS offering."
