RK
Cloud Security & Governance at a financial services firm with 10,001+ employees
A comprehensive data management solution shows potential for improvement while providing strong integration with existing infrastructure
One of the requirements is to have data leak policies and data access policies. This is very critical to enforce data governance standards, which relate to data classification, access control, data protection, and retention. It covers the entire lifecycle, helping us to protect, detect, and classify the documents. Challenges are mostly related to the security products onboarded into the bank; they have challenges in terms of those products complying with the internal standards. Sometimes, we cannot just use the DLP across the state. For example, using Microsoft products has been easy to adopt, such as OneDrive and SharePoint on-premise, but it becomes a challenge when it comes to AWS, as data also exists in S3 buckets. Testing is still ongoing, but it will eventually be done. The time it takes to scan is one issue; when we raise high-volume issues and tickets related to scanning failures, it relates to permission errors, which are technical challenges. These take time because we have high volume tickets in terms of connectivity, scanning failures, and related matters. There are also frequent change requests, especially regarding scoping or rescoping due to complexities, creating several challenges. In both organizations I work with, there are gaps, and there is no enterprise-wide data classification available. However, there are pockets of implementations for various products. Some agencies are using it, but otherwise, there's no product existing across the enterprise. Microsoft Purview Data Lifecycle Management is definitely a good solution, but there is significant room for improvement from a product perspective. Reporting is another area that needs improvement.
HS
Email Security Engineer at Logic Infosecurity
Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The UI is the most valuable feature."
"The impact of Microsoft Purview Data Lifecycle Management on my unified data catalog has improved a lot; the improvements I see are in the lineage, the discovery, and the labeling."
"The system is stable; I haven't encountered any worldwide stability issues unlike other office products."
"HPE Apollo Systems has positively impacted our organization by improving business operations by eighty percent, saving time, improving efficiency, and facilitating the management of large data sets."
"The solution offers good technical support."
"I recommend Mimecast based on customer requirements and budget."
"Mimecast has been in the market for a long time; it's a good tool if you want to simplify your operations and a good tool for removing on-prem appliances that otherwise you would need to do with the protection that Mimecast provides."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"Email security is the most valuable feature of the solution."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
 

Cons

"The time it takes to scan is one issue; when we raise high-volume issues and tickets related to scanning failures, it relates to permission errors, which are technical challenges."
"Microsoft's Purview Data Lifecycle Management preview features can be unreliable, hindering their usefulness."
"I think labeling could use a lot more AI assistance. AI implementation into labeling would be beneficial."
"There is no specific improvement I would suggest for Microsoft Purview Data Lifecycle Management, but I think if they can work on policy design and usability, adding more granular control for the organization regarding controlling the movement of data outside would definitely improve the solution."
"The differentiation between bulk spam mail and campaign-related mail could be improved."
"External security features need improvement."
"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."
"Technical support has been slower than it was in the past, likely due to the pandemic."
"The product's interface could be improved to be more user-friendly."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"The price of the solution is expensive. It can improve by reducing the price."
"The solution is complex and not easy to use."
 

Pricing and Cost Advice

"The service operates on a pay-as-you-go basis, charging an extra one cent per field of metadata scanned in our data."
"It is a bit expensive."
"The price of Mimecast Mailbox Continuity is expensive."
"The licensing costs are per-user for the product that you get with them."
"For what it is, the product is overpriced."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"The product price is moderate. I rate the pricing a five out of ten."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
"The solution is expensive."
