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 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."
"Customer support is excellent."
"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."
"I recommend Mimecast based on customer requirements and budget."
"The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."
"My advice to those considering this product would be to go for it."
"Mimecast Mailbox Continuity helps companies continue to move."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"Mimecast has some good support services in place."
 

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."
"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."
"The product should incorporate more automation with the help of AI."
"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."
"The solution is expensive in comparison to similar solutions."
"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"External security features need improvement."
"The interface isn't the best. How everything works on the back end is confusing."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"The solution is complex and not easy to use."

"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
