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.

Centralized archiving has transformed how we manage compliance, audits, and investigations
Overall Proofpoint Intelligent Compliance Platform is a strong platform for compliance and information governance, but there are a few areas where it could improve in the future. One improvement area is the user experience and interface consistency across different modules. Some workflows can feel complex, especially for a new user or the team managing multiple compliance functions simultaneously. Community feedback has also highlighted that certain administrative interfaces and navigation flows could be more modern and streamlined. I also think there is room for improvement in support responsiveness and operational simplicity for complex deployments. Some users in the community have mentioned challenges around the ticket response time and troubleshooting efficiency for advanced configurations that needs to be improved. From a product perspective, a continued investment in AI-driven detection, the reduction of false positives, and easier policy tuning would make the platform even more effective at scale. Proofpoint already provides strong automation and machine learning capabilities, but a highly regulated environment still requires significant tuning and oversight to optimize the workflow. One additional improvement for Proofpoint Intelligent Compliance Platform would be making policy configurations and workflow management more intuitive, especially for organizations with complex compliance structures and multiple regulatory requirements. I also think more customizable dashboards and reporting capabilities would help teams gain faster operational insight and improve visibility into the compliance trends, investigations, and reliable workload.

Quotes from Members

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

Pros

"URL inspection works pretty well."
"We like the content filtering and secure messaging features."
"Email security is the most valuable feature of the solution."
"The solution is stable and reliable. There are no bugs or glitches, and it doesn't crash or freeze."
"Mimecast certainly helped my customers reduce phishing emails."
"Mimecast has some good support services in place."
"Mimecast Advanced Email Security positively impacts my organization by filtering spam emails."
"The most valuable feature is the DMARC Analyzer."
"Overall, Proofpoint Intelligent Compliance Platform is a very strong and reliable platform for compliance, archiving, supervision, and information governance."
"Our experience with the platform has been positive as it has maintained consistent control over spam and malware threats."
 

Cons

"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."
"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 solution is expensive in comparison to similar solutions."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"The feature that should be included is to remove the block on the encrypted files."
"The solution is complex and not easy to use."
"This solution can be frustrating. It blocks many things that should be going through."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"Some workflows can feel complex, especially for a new user or the team managing multiple compliance functions simultaneously."
"The Proofpoint Intelligent Compliance Platform does not provide features that help reduce manual efforts, so additional human resources are still required to manage security."
 

Pricing and Cost Advice

"The licensing costs are per-user for the product that you get with them."
"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 customers can select the license packages as per their requirements."
"The product has good pricing in terms of return on investment."
"It's an expensive solution."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a 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."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
