Decreased our security alerts without impacting employees' work
I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace. It provides a single console for security policy and management. That is somewhat important because we used to have other products where you would have to log in to individual appliances, devices, or clusters. Having one spot to log in to or one area to go to for doing different tasks and viewing data sources, just makes it easier from a user perspective. Also, the fact that it's invisible to our end-users and doesn't affect their work is very important. Most companies don't want to have added friction or impact on their users. In addition, the combination of user-friendliness for admins, and security for the organization, works well. As a cloud-hosted solution, it provides ease of use.

Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks
Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.

Quotes from Members

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

Pros

"Menlo Security RBI's best feature is its threat isolation engine."
"Menlo Security RBI has a very good record on stability."
"I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace."
"In addition, the combination of user-friendliness for admins, and security for the organization, works well."
"The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."
"We like the content filtering and secure messaging features."
"Mimecast Mailbox Community is an email gateway required for every organization, regardless of size."
"The anti-spam handling is very good, as it picks up a lot of junk, malware, and other threats."
"The solution's performance is good."
"I would rate Mimecast Email Security a nine out of ten."
"The solution offers good technical support."
"Mimecast Advanced Email Security blocks everything effectively and provides an update indicating whether you want to release or delete it."
 

Cons

"There are several features, such as supporting web technologies, that the company is working on implementing in the platform. There are a lot of backend web technologies in use on various websites, for example, two-way audio/video and WebGL, for which support may not be fully implemented in the product."
"Menlo Security RBI could be more cloud-friendly, and its mobility could be improved."
"Menlo Security RBI can be very costly."
"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."
"Moving forward, there is concern about AI and security."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"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."
"The solution is expensive in comparison to similar solutions."
"What can be improved with Mimecast Advanced Email Security is around the Brand Exploit Protect tool; the turnaround times to take down sites or block them in the meantime are a bit slow, and the detection of brand exploitation out in the world could be better."
"The installation is not so straightforward."
"Mimecast Advanced Email Security is adequate, but it has remained the same since the last two years with not much research and development."
 

Pricing and Cost Advice

"Menlo Security RBI can be very costly."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The licensing costs are per-user for the product that you get with them."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
"For what it is, the product is overpriced."
"The price of Mimecast Mailbox Continuity is expensive."
"It's an expensive solution."
"The product price is moderate. I rate the pricing a five out of ten."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
