Featured Reviews

Jamie LeClair - PeerSpot reviewer
File-sharing options and ease of collaboration or meetings allow for quick collaborations and chats
I work in my company's IT department, so I use all of the products under Office 365 daily, including Microsoft Word, Microsoft PowerPoint, Microsoft Teams, and all the other components in the product. My company can't make it through a day or go by without using the products offered under Office 365. Some of our manufacturing workers may use Office 365 a lot less, but it is still necessary for things like Microsoft Outlook and Exchange. I found Microsoft Teams to be the most valuable feature of the solution, along with all of the products and features offered under Office 365. My organization has remote workers, and we can't run the company without meetings organized with the help of Microsoft Teams.
Andras Solt - PeerSpot reviewer
Reasonable pricing and good spam filtering but does not offer robust gatekeeping
It's mainly suited for mid-size companies, not for bigger companies like us. We are more than 1,000 people. In fact, we're over 2000 users, so that's why we investigated some other products, and Clearswift, for example. We likely won't increase usage. We're looking at GFI in a year or so.
Frank Rawson - PeerSpot reviewer
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 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."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"The product is not resource-intensive."
"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."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"The email protection is excellent, especially in terms of anti-phishing policies."
"Does a thorough job of examining email and URLs for malicious content."
"The product helps users handle security challenges as it offers prefiltering options and does relatively good incident reporting."
"After implementing FortiMail, the spam, and malicious emails we receive have significantly reduced, making it much simpler to manage."
"Fortinet FortiMail's most valuable features are its performance and security."
"One major benefit of the Fortinet FortiMail product is its ease of management."
"This excellent email gateway minimizes spam, inspects suspicious emails and isolates infected attachments with little administrative effort."
"The anti-spam features are valuable."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"Technical support is great. They're available 24/7 and their response time is typically within the hour."
"Mimecast certainly helped my customers reduce phishing emails."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"URL inspection works pretty well."
"The initial setup is easy."
"It's good, it keeps the spam out."
"It offers an easy initial setup."
"The most valuable feature is the DMARC Analyzer."
 

Cons

"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"The pre-sales cost calculations could be more transparent."
"Microsoft Defender for Office 365 should be more proactive."
"There is room for improvement in terms of reporting."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"The XDR dashboard has room for improvement."
"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 biggest room for improvement would be the deployment. It will be hard for someone who doesn't understand the interface to deploy. If you understand it, you can find your way around the problems."
"I don't know if it is possible, but I would like to see Artificial Intelligence and machine learning introduced."
"The logging information is sometimes not clear or easy to understand."
"Header inspection and containerization, like on-prem premises sandboxing, need enhancement."
"Fortinet FortiMail should allow more flexibility with the content rules."
"I believe there is room for enhancement in content and web security features."
"I think they need to look into it and improve their signatures. This will help with blocking incoming spam emails."
"Sometimes, authentic emails get blocked by the solution's firewall."
"They should improve the cookies management feature."
"The solution is complex and not easy to use."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"The tool can be challenging because it relies on rule-based configurations, especially for addressing impersonation threats. This approach requires setting up numerous rules to ensure filtering. It should work based on behavior-based analytics."
"The product's interface could be improved to be more user-friendly."
"External security features need improvement."
"The attachment scanning feature doesn't work properly."
"The detection rates are an area for improvement."
 

Pricing and Cost Advice

"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."

"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The pricing has become expensive."
