Helps to detect and generate reports on phishing emails and saves from email compromises
We use the solution for marketing and brand protection.  I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature.  The product's…

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

"It is really important for large companies to have the brand protection that is provided by Agari."
"They are very flexible as far as feature requests go."
"Agari gives us visibility of our domain security, helps us manage our SPF, DKIM and DMARC records, prevents spoofing of our domains for phishing and ensures that our marketing and other emails are received correctly and not rejected as spam."
"Agari offers very good brand protection and they are the core founder of the DMARC standard."
"I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature."
"It comes with a lot of helpful tips for complicated areas."
"If spam or some kind of malicious email gets past Mimecast and gets into our email environment, we can go into Agari and we can search for it."
"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."
"I recommend Mimecast based on customer requirements and budget."
"It offers an easy initial setup."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"The setup was easy."
"The solution offers good technical support."
"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."
"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."
 

Cons

"Some customers in the financial sector do not like the cloud solution because they don't want data to be transferred to a US-based cloud."
"The product's user interface is clunky. We have difficulty in finding what we need. I would also like to see automation in the onboarding processes."
"The protocol is quite complicated, which may not be something that could be improved, but it would be better if it was simplified."
"The product's interface could be improved to be more user-friendly."
"The filtering needs more flexibility."
"While it's quick and easy, the initial setup could be more user-friendly."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
"It was not a good experience due to the fact that our main infrastructure had a problem for that entire time."
"Its pricing can be improved. It is a bit expensive."
"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."
"The interface and the documentation could be improved."
 

Pricing and Cost Advice

"The pricing depends on the number of users; per how many mailboxes you have, but they're pretty negotiable with that, too."
"The tool is not expensive and I would rate its pricing a four out of ten."
"The price of the licensing is based on the volume of email."
"It's an expensive solution."
"For what it is, the product is overpriced."
"The licensing costs are per-user for the product that you get with them."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"The customers can select the license packages as per their requirements."
"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."
"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."
"I'm always going to say the price needs to be lower, but it's reasonable."
