Email defenses have reduced phishing risk and support strong compliance and user awareness
The improvement needed is not necessarily in the product itself, but rather around how other organizations have evolved. The DLP discussion is no longer limited to email; it has gone to border level with companies like Zscaler, Netskope, and Palo Alto giving the complete full-stack SASE setup. When somebody has a SASE setup, then Mimecast Advanced Email Security DLP might not even be needed at a point in time. Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere. The second thing is when you buy an XDR provider, they give you a complete holistic story around it, showing what has happened, which email somebody has clicked on, whether there have been any changes, and whether there is any network activity. You get a holistic picture. When pushing Mimecast Advanced Email Security to end customers, people are more often saying that they would rather buy XDR from another provider because the story when an analyst sees is complete in terms of what they see, whereas they only get an email story from Mimecast Advanced Email Security. Mimecast Advanced Email Security has to improve there. Companies like Abnormal AI cover more on UEBA and user behavior, and there are many things for Mimecast Advanced Email Security to improve in this area as well. It is less of a technology issue; they are doing very well on email. The conversation for them to have is on how to get into a broader level or how to get a tie-up to become a broader supplier. At least from a service provider landscape, I can say that.

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.

"We discussed the phishing aspect, the DNS system, and the key rotation."

"Mimecast Advanced Email Security needs to improve in this area because they are only focusing on a particular set of problems which is on email and human risk, whereas companies that need a slightly bigger picture will look elsewhere."

Pricing and Cost Advice

"The solution is expensive."
"The product price is moderate. I rate the pricing a five out of ten."
"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."
"I'm always going to say the price needs to be lower, but it's reasonable."
"It's an expensive solution."
"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 licensing costs are per-user for the product that you get with them."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
