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.

Pros

"It is really important for large companies to have the brand protection that is provided by Agari."
"Agari offers very good brand protection and they are the core founder of the DMARC standard."
"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."
"They are very flexible as far as feature requests go."
"It comes with a lot of helpful tips for complicated areas."
"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 does a good job for us, and its admin console is easy to use."
"The initial setup is very straightforward."

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."
"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."
"This solution can be frustrating. It blocks many things that should be going through."
"The feature that should be included is to remove the block on the encrypted files."
"Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts."
"While it's quick and easy, the initial setup could be more user-friendly."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"The filtering needs more flexibility."
 

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 price of the licensing is based on the volume of email."
"The tool is not expensive and I would rate its pricing a four out of ten."
"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."
"The customers can select the license packages as per their requirements."
"It is a bit expensive."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"For what it is, the product is overpriced."
