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.

Helps to detect and generate reports on phishing emails and saves from email compromises
We use the solution for marketing and brand protection.  I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature.  The product's…

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

"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"There are several features that I consider valuable."
"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."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"Microsoft Defender for Office 365 is a stable solution."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"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."
"If spam or some kind of malicious email gets past Mimecast and gets into our email environment, we can go into Agari and we can search for it."
"It comes with a lot of helpful tips for complicated areas."
"It is really important for large companies to have the brand protection that is provided by Agari."
"I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"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."
"We like the content filtering and secure messaging features."
"I recommend Mimecast based on customer requirements and budget."
"The most valuable feature is the DMARC Analyzer."
"It's good, it keeps the spam out."
"The product is good. To date, we have not faced any challenges."
"The solution is pretty straightforward to use and easy to set up."
 

Cons

"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"You should be able to deploy Defender for every subscription without the need to add servers."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Several simulation options are available within 365, and the phishing simulation could be better."
"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."
"There's room for improvement regarding the time frame for retrieving emails."
"We need to be able to whitelist data at the backend."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"The product's user interface is clunky. We have difficulty in finding what we need. I would also like to see automation in the onboarding processes."
"Some customers in the financial sector do not like the cloud solution because they don't want data to be transferred to a US-based cloud."
"The protocol is quite complicated, which may not be something that could be improved, but it would be better if it was simplified."
"Its pricing can be improved. It is a bit expensive."
"They could provide a unified licensing model, including all the security features."
"The installation is not so straightforward."
"As a user, the user interface of the management console could be upgraded, for example."
"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."
"While it's quick and easy, the initial setup could be more user-friendly."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The platform's cost-effectiveness could be improved."
 

Pricing and Cost Advice

"The product is very expensive."
"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."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"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."
"It's a user-base subscription."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The tool is not expensive and I would rate its pricing a four out of ten."
"The pricing depends on the number of users; per how many mailboxes you have, but they're pretty negotiable with that, too."
"The price of the licensing is based on the volume of email."
"There are additional costs beyond the standard licensing fee."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."

"It is a bit expensive."
