System Engineer II at a media company with 5,001-10,000 employees
It easily generates reports about the kinds of emails coming in weekly and classifies them into various categories, making it very helpful to analyze and ensure our email gateway remains safe and secure by updating all security patches.

A distinct advantage of Mimecast is its ability to block phishing and impostor attacks, which are significant threats currently.

Most times the hardware comes as an appliance with a fixed set of storage, which means that you cannot scale out that storage with any other OEM. You must use Veritas.
Head, Datacenter and IT Enterprise Applications at GTBANK
Indexing is one of the most important features because without indexing we don't have access to the data.
Backup Admistrator at Government of Poland

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.

Support for data archiving and integration capabilities enhance data management
The GUI of Veritas Enterprise Vault is not friendly; the user interface can be quite convoluted for users or IT people who are not conversant with it. Even for professionals, it can be complex. Over time, if you get the hang of it, you'll understand it, but it's not something you can teach a user to quickly grasp. It's kind of complex. Veritas could do something to change this situation. I've given feedback quite a number of times through various channels, including during support calls. I remember trying to do a system state backup using our NetBackup feature, and I found out that Veritas NetBackup cannot back up a system state. Having numerous solutions instead of just one backup system can be quite unfriendly. They can back up other things such as databases and file servers, but when it comes to carrying a system state backup, it falls short. Honestly, Veritas Enterprise Vault's costing was one of the main reasons we dropped the integration to the cloud.
