An effective email security solution that provides DLP, Safe Attachment, and Safe Links
If you want extensive email security, you need to purchase a Plan 2 license. Plan 1 and Plan 2 are the two plans for Microsoft Exchange Online Protection. Some customers hesitate to purchase this product because it adds some costs to them, which is necessary for them. It would be helpful for customers if Plan 1 features were included with EOP. However, they still need to purchase Plan 2 for advanced security features. One of our clients recently requested to compare Zimbra's features with Microsoft Exchange Online Protection. Zimbra is open source, while Microsoft Exchange Online Protection is not. When I compare both the products, many free features are available in Zimbra because it is open-source software. It makes no sense to request Microsoft Exchange Online Protection add all the features people get on open-source software like Zimbra. Hence, I would say whatever features Microsoft Exchange Online Protection has are enough. Microsoft has a dedicated research team that should research and add new techniques like phishing and spamming solutions to the 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

"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"The initial setup of Microsoft Exchange Online Protection was easy."
"The product's most valuable feature is third-party integrations."
"The most valuable feature of Microsoft Exchange Online Protection is the accidental release of information protection capabilities. Additionally, the solution is easy to use."
"Microsoft EOP's most valuable feature is a shared mailbox."
"The security features provided by Microsoft are robust."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"The setup was easy."
"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."
"The initial setup is easy."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"URL inspection works pretty well."
"Mimecast certainly helped my customers reduce phishing emails."
"The most valuable feature is the DMARC Analyzer."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
 

Cons

"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"Microsoft has some training portals, but more could be developed."
"The product could be more stable. Microsoft products could be more stable because sometimes, even though they are updating some things, we cannot find those updates."
"The biggest issue that I experience is that Microsoft keeps moving things around, and it's very inconsistent as to where you find the information when you're trying to work on different pieces."
"Performance and speed should continue to be improved."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"The security features could be better."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"The solution is complex and not easy to use."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"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 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 detection rates are an area for improvement."
 

Pricing and Cost Advice

"The price could be lower."
"The tool's pricing is excellent."
"It is a low-price solution."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"The solution falls on the higher or more expensive side of the spectrum."
"The product is bundled with Microsoft 365."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
