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.

It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.

Quotes from Members

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

Pros

"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"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."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"The technical support is good and quick to resolve issues."
"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."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"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."
"Spam protection is the most valuable feature."
"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."
"Easy to use for non-technical users."
"Avanan is a stable software. My company hasn't faced any issues, bugs, or problems with the performance of Avanan."
"The threat detection tools enable us to ascertain malware and phishing messages across the email network infrastructure."
"When we don't understand some functionalities, the customer support staff responds fast to our calls and provides immediate action."
"It is simple to deploy this platform and interact with the set features."
"We like the content filtering and secure messaging features."
"The solution's performance is good."
"The solution offers good technical support."
"The solution is scalable."
"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
"It's good, it keeps the spam out."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
 

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."
"The XDR dashboard has room for improvement."
"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."
"There's room for improvement regarding the time frame for retrieving emails."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"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."
"The phishing and spam filters could use some improvement."
"Microsoft Defender for Office 365 should be more proactive."
"There are times when we have false positives."
"When sending bulky emails, the system slows down and takes a long time before it responds effectively to our requests."
"It should also offer a quick backup in case any email is wrongly quarantined or deleted to ensure no data loss."
"Familiarization with performance for new teams may take a long time."
"They should come up with a mobile application so that it can be more flexible."
"It is very difficult to find the required documentation."
"The system could be designed to give corporate emails first priority due to demands."
"In Avanan, the email channel is one of the channels where data leakage happens, and they need to consider it from a DLP perspective."
"The detection rates are an area for improvement."
"External security features need improvement."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"The solution is very expensive."
"I'd like to have better support from the product in the future."
"The product's interface could be improved to be more user-friendly."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
 

Pricing and Cost Advice
