Dashboard functionality and data processing offer value with an easy setup
We are using Microsoft Purview Customer Lockbox for email access The most important feature is data processing. I like the dashboard and the undo or multi-call feature of Microsoft Purview Customer Lockbox. The pricing for personal users is not cost-effective. It feels expensive for individual…

Email defenses have blocked advanced threats and provide deep visibility into risky users
The areas that have room for improvement in Proofpoint Email Protection include their cost of ownership, which is fairly high. To manage and run all their products, I have to list and manage administrators in seven or eight different places. That is too many places to keep track of since for this tool I have to go to one location, and for another tool I have to go to a different location. They need to simplify the administration management of administrators and consolidate that into one place for all their products. Access to all the different products is very scattered. For some products I go to one URL, and for different products I go to a different URL. They have a threat URL that has most of their products in it, but not all. They need to simplify the interface to show all the products I have access to in one location.

Quotes from Members

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

Pros

"The most important feature is data processing."
"The archive feature is valuable."
"The tool has improved our workflow by ensuring people receive only the emails they need for work rather than being inundated with hundreds or thousands of unnecessary emails daily."
"The solution offers very good flexibility. You can blacklist or whitelist with ease."
"It was easy to set up."
"Proofpoint Email Protection is the best solution from the perspective of email security."
"The Phish Alarm button allows users to submit questionable emails for review and complete analysis."
"Its anti-phishing functionality is the most valuable. Certainly, the biggest problem I have is phishing."
"The solution is very user-friendly."
 

Cons

"The pricing for personal users is not cost-effective."
"Proofpoint Email Protection has a new approach to email security with its API feature. Currently, it only works with Office 365. In the future, it would be beneficial if it also works with Gmail, as Check Point is currently the only brand that has API email security for Gmail. It would be beneficial if Proofpoint Email Protection could add this integration, they would be more competitive with other vendors."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"The flexibility of the solution can be improved."
"The largest complaint that we hear from our customers is that there is no local support."
"They do not have an on-demand scan for the internal viruses and internal users, and they don't have a scan for the exchange server against viruses and spam as Symantec does."
"The reporting section could be enhanced. I like some reports but if they could allow us to create custom reports with more flexibility it would enhance the reports more."
"The email DLP portion could be a bit easier."
"The solution could lower its price."
