The main area for improvement is simplifying the implementation and rollout process.

Two years ago, compared to today, the costs rose almost four times, and that is why we are not happy with it.

It ranks the threats and allows us to prioritize those hitting us the hardest, such as email threats.
It provides end-to-end visibility on email threats such as phishing, extending beyond Exchange Online Protection.
The value of the DLP feature is significant to us because we have internal data, sometimes sensitive, and the users may not always be aware of security and privacy, which might lead them to send out information mistakenly to external parties.
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.
Two years ago, compared to today, the costs rose almost four times, and that is why we are not happy with it.

Featured Reviews

Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

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.
