Senior Tech. Lead at WE
Mimecast Email Security is somewhat expensive compared to the competition in the Indian market.
Co-Founder & VP-Sales at QuantumShield Technologies LLP

I would apply different policies to classify or categorize emails such as spam or not spam and inspect the content of the email and attachments to check for viruses or malware.

Prices range from 11 to 12 dollars for licenses and can fluctuate up and down.
CEO at Haniya Technologies
A great benefit is that if you buy a license for 100 servers and 100 mailboxes, and if your mailboxes increase to 120 while your servers decrease to 80, you can reallocate credits from unused email security to your mailboxes.

Featured Reviews

Avinash Mishra - PeerSpot reviewer
Manager - EUC at Finthrive
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.
AsadAli - PeerSpot reviewer
Soc Team Lead at Super Secure
Centralized protection has transformed email security and incident investigations by reducing false positives and improving behavioral threat detection
The challenges include the challenge of finalizing a product that has all the security features or capabilities that are usually required. For example, if there is an EDR platform that's just monitoring IDS signatures, it won't be as beneficial as one with behavioral monitoring and other critical aspects required according to the best practices of the industry. Additionally, if there is a product that can provide a centralized view Trend Vision One does, it really grabs the customer's interest because customers usually don't have to buy separate EDR, XDR, or SIEM solutions or a console for their SOC analyst or email security team. These challenges consist of managing multiple teams and products. Trend Micro Email Security comes in and solves these problems.Trend Micro Email Security is generally a bit more difficult to implement compared to the rest of the solutions such as network security modules or EDR modules, which are much easier. Trend Micro Email Security has some complexities in implementation, but there aren't any significant shortcomings that require Trend Micro to improve.
