Data lineage and quality checks have streamlined team-wide collaboration and business context
The biggest friction point or frustration I have encountered with Microsoft Purview Communication Compliance is cost-wise it is acceptable, but sometimes unexpected errors will occur, though this happens very rarely. There are features I wish Microsoft Purview Communication Compliance had that it does not provide today. Enterprise-level lineage is one such feature. As of now, if Microsoft were to provide this tool for free when you buy Microsoft Fabric, I feel that would be better. This would also result in lower license costs. I do not have any changes I would make to Microsoft Purview Communication Compliance at this time.

Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks
Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.

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."
"Microsoft Purview Communication Compliance has impacted my organization positively; it is a good tool that provides an end-to-end business view for a particular organization."
"Customer support is excellent."
"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."
"Microsoft Purview Communication Compliance helps with extra collaboration and ensures communication is within the framework."
"Mimecast Advanced Email Security has positively impacted our organization by securing our environment better than before compared to what we used to configure earlier to deliver the email."
"We like the content filtering and secure messaging features."
"The solution's performance is good."
"If you want the ease of use, then Mimecast, or at least a cloud solution, is the way to go."
"It offers an easy initial setup."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"Mimecast Mailbox Continuity helps companies continue to move."
 

Cons

"The biggest friction point or frustration I have encountered with Microsoft Purview Communication Compliance is cost-wise it is acceptable, but sometimes unexpected errors will occur, though this happens very rarely."
"Monitoring and compliance for web applications could be improved."
"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."
"The interface and the documentation could be improved."
"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 system is not user-friendly because you have to create policies that are mapped in a dictionary."
"The solution is very expensive."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you about the problem you're reporting."
"The filtering needs more flexibility."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"The feature that should be included is to remove the block on the encrypted files."
 

Pricing and Cost Advice

Information not available
"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."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"The solution is expensive."
"For what it is, the product is overpriced."
"The product has good pricing in terms of return on investment."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"I'm always going to say the price needs to be lower, but it's reasonable."
