Customer Service

Sentiment score
6.1
Digital Guardian customer support efficiency varies; users praise global help but note inconsistency in response time and technical understanding.
Sentiment score
8.3
Mimecast provides reliable, effective customer support with knowledgeable staff, useful resources, and multiple support channels, despite occasional delays.
For vendor support, such as Fortra support, I would rate it a seven because all the support comes from different parts that sometimes have challenges meeting time zones, and sometimes they reroute to distributors and rely on partners.

Room For Improvement

Digital Guardian needs to enhance partner programs, policy simplicity, cross-platform features, resource efficiency, cloud integration, and technical support.
Mimecast could enhance reporting, integration, and analytics, improve UI performance, and support additional devices for better risk management.
The issue is that it works only with users or companies with more than 500 users.
Cyber Security Researcher at a tech services company with 11-50 employees
Digital Guardian can generate false positives initially, which can be significantly reduced through proper policy tuning and data classification.
Sr.Technical Support Executive at Digitaltrack Solution Private Limited
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.
Security Engineer at Comcast
Mimecast Insider Risk Management and Data Protection should incorporate features to detect if a URL is malicious or generated by AI, especially since many attackers use scripts to bypass mail gateways.

Network Security Engineer at a tech services company with 1,001-5,000 employees
 

Setup Cost

Digital Guardian is costly but ideal for enterprises needing strong data loss prevention, especially in manufacturing.
Mimecast's pricing is reasonable with valuable support, scalable user licenses, and potential discounts for larger or long-term deployments.
The setup cost is a one-time investment that will stay with us forever.
Security Engineer at Comcast
After migrating, the cost is almost a 50% discount.
Infrastructure Contractor at a real estate/law firm with 11-50 employees

Featured Reviews

Syed Mubeen - PeerSpot reviewer
Cyber Security Researcher at a tech services company with 11-50 employees
Enterprise data protection has supported regulatory compliance and integrates with classification tools
In terms of functionality, many features are valuable in Digital Guardian, as the first thing for most customers is that they are using solutions such as Boldon James and Titus, which fall under the classification side, and Digital Guardian can easily integrate with this data classification solution and has a very granular level of configuration and policy tuning. Digital Guardian's data protection policies are indeed useful for my clients. Regarding Digital Guardian, I find it to be a very good solution, and in fact, it is an enterprise-level solution that has very tight integration with most of the products, with Fortra but also with others.
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.
