Featured Reviews

Emeka Ndulu - PeerSpot reviewer
Cloud Solutions Architect at a tech services company with 201-500 employees
Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.
Charles Nwaokukwu - PeerSpot reviewer
Head, Datacenter and IT Enterprise Applications at GTBANK
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.
