Automation Engineer at a tech vendor with 10,001+ employees
If Mimecast could provide more information about how they store the data and whether the agents are local agents or cloud-hosted agents, that would be of great help for the organizations to consider its AI capabilities while adhering to the compliance needs of a particular organization.

Featured Reviews

Lucianofernandez Fernandez Moroaga - PeerSpot reviewer
Automation Engineer at a tech vendor with 10,001+ employees
Security has protected data quietly and now needs to give users more visibility and control
Regarding how Fortra's Digital Guardian can be improved, the fact that it runs as a background process isn't necessarily a bad thing, but you don't get any visibility into what it's doing unless a security policy is triggered. In the future, they could improve that to give users more visibility about what's happening. I give Fortra's Digital Guardian a seven because it doesn't compromise my system performance, but I don't get any visibility about what's happening and I don't know which criteria are used for preventing data leaks or classifying my files as sensitive or not sensitive. I would give it a ten if it had more visibility about what's happening or more contact with the user. Regarding the accuracy and reliability of Fortra's Digital Guardian's output, since it's fully managed by my company's IT department, I don't get any visibility of what processes it runs internally, so I don't know how it classifies the files. Therefore, I cannot give you a certain answer about that.
External Ganesh - PeerSpot reviewer
Security Engineer at Comcast
Insider threats have been detected faster and internal data exposure is now controlled
Regarding how Mimecast Insider Risk Management and Data Protection can be improved, sometimes the tool is slightly laggy, wherein it would take some time for us to fetch the related logs from the Mimecast portal, and that of course can be improved. There could also be a graph or a kind of a graph where, if the organization has a smaller number of employees, it is fine, but if it has a large number of employees and different departments, then in that case, Mimecast could give us an AI suggestion upon how to improvise the current security posture, how we stand and where we can go up to in terms of implementing or tweaking the policies. As the organization's size gets bigger, it would also be better if Mimecast could provide some solutions upon how to segregate the users into groups and what groups can have which policies. Those kinds of features can be added. Regarding Mimecast Insider Risk Management and Data Protection's AI capabilities, I think its governance and security could improve as I am not entirely sure how it works. It would be helpful if Mimecast could, as the AI capabilities are in place, maintain a strict governance policy upon the data that is being processed, especially for user personally identifiable information. As insider risk management sometimes also gets into the personal details of the user, organizations might be hesitant; even we are also hesitant to use the AI capabilities. If Mimecast could provide more information about how they store the data and whether the agents are local agents or cloud-hosted agents, that would be of great help for the organizations to consider its AI capabilities while adhering to the compliance needs of a particular organization.
