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 Large File Send feature comes in handy when you have to send fairly large attachments."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"The most valuable feature is the DMARC Analyzer."
"Mimecast has been in the market for a long time; it's a good tool if you want to simplify your operations and a good tool for removing on-prem appliances that otherwise you would need to do with the protection that Mimecast provides."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"I would rate Mimecast Email Security a nine out of ten."
"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."
"From the tools I have worked with, it is actually the best, and I am happy with it."
 

Cons

"Menlo Security RBI could be more cloud-friendly, and its mobility could be improved."
"Menlo Security RBI can be very costly."
"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."
"I'd like to have better support from the product in the future."
"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."
"It analyzes patterns but sometimes overlooks suspicious indicators."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"The feature that should be included is to remove the block on the encrypted files."
"The filtering needs more flexibility."
"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."
 

Pricing and Cost Advice

"Menlo Security RBI can be very costly."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a 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."
"The product price is moderate. I rate the pricing a five out of ten."
"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."
"It's an expensive solution."
"The solution is expensive."
"For what it is, the product is overpriced."
"It is a bit expensive."
