Facilitates compliance and records management but needs user-friendly enhancements
The features I appreciate the most in Microsoft Purview Communication Compliance include the ability to build cases, give them dates, and find them based on the notes that I left behind. The importance of Microsoft Purview Communication Compliance building taking into account critical regulations from around the world is very significant. It helps us stay up to date. While I don't need the functionality, Purview delivers data protection across multi-cloud and security platform environments, including AWS and GCP. It takes into account critical regulations from around the world. It helps us stay up to date with what's going on. We can show compliance in real-time. It's very easy to pull records. The time it saves is very useful.

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 time it saves is very useful."
"Customer support is excellent."
"Microsoft Purview Communication Compliance helps with extra collaboration and ensures communication is within the framework."
"The features I appreciate the most in Microsoft Purview Communication Compliance include the ability to build cases, give them dates, and find them based on the notes that I left behind."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
"If you want the ease of use, then Mimecast, or at least a cloud solution, is the way to go."
"The security on offer is very good."
"Mimecast is a brilliant product; it works very well, I have very seldomly, if ever, had any problems with it, and it does exactly what it promises to do."
"In terms of technical superiority and the product itself, there are no complaints."
 

Cons

"The product should incorporate more automation with the help of AI."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
"Monitoring and compliance for web applications could be improved."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
"The filtering needs more flexibility."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult."
"The price could be better, it should be reduced."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"The lock in is very, very tight. It is impossible to move out of Mimecast to a different product, like Proofpoint or 365 ATP, and keep the chain of custody for every email that I've archived."
"The solution is very expensive."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
