Great protection, good privacy, and helpful support
The only thing I would like is a way to open the email that is going to quarantine. Based on the level of security, they cannot open the email to check the message. Even for the administrator, you have to create a security copy to be sent, which will lock the log support. It's not easy for an admin to check and decide if the email is good or not. That is the only thing that I'm seeing could be improved. Basically, ESET doesn't have the ability to let the administrator release an email showing the message on the email. It's not possible. If you want to have an email review, you have to select an option to send a copy. In the way that they designed the system, for security, they are not letting anyone even have the admin privileges to make this happen. Privacy is at a really high level.

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

"We are close to having 99% or 98% detection."
"It's a trustworthy solution that is easy to learn."
"The most valuable features are the precision of detection and the level of customization of the policy."
"The solution is pretty straightforward to use and easy to set up."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"My advice for others looking into using Mimecast Advanced Email Security is that they can strengthen their security very well if they choose to go with it."
"Overall, I consider Mimecast Advanced Email Security to be a reliable and effective security solution, with the highest value for organizations that face significant phishing and email-based threats and are willing to invest time in proper configuration and monitoring."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"Mimecast Advanced Email Security has positively impacted our organization by securing our environment better than before compared to what we used to configure earlier to deliver the email."
"Mimecast has some good support services in place."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
 

Cons

"The specific domain file for Apache needs to be well-defined."
"It's not easy for an admin to check and decide if the email is good or not."
"This solution can be frustrating. It blocks many things that should be going through."
"External security features need improvement."
"The differentiation between bulk spam mail and campaign-related mail could be improved."
"The installation is not so straightforward."
"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."
"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."
"They should improve the cookies management feature."
"The attachment scanning feature doesn't work properly."
 

Pricing and Cost Advice

"The solution provides affordable pricing for medium sized industries."
"It's an expensive solution."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"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 licensing costs are per-user for the product that you get with them."
"The price of Mimecast Mailbox Continuity is expensive."
"It is a bit expensive."
"The customers can select the license packages as per their requirements."
