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 most valuable features of Proofpoint Email Protection are the performance from being on the cloud."
"Proofpoint provides an expandable project model, including DLP, email archiving, and encryption, which makes it a complete email security solution."
"There is no downtime."
"The solution scales quite well."
"It was easy to set up."
"The anti-spam features are excellent on the email firewalls."
"Proofpoint Email Protection offers an additional layer of protection compared to other brands like Microsoft, Mimecast, and Barracuda. While these major companies excel at detecting malicious attachments, the solution goes further by analyzing the context of emails, allowing for more nuanced decision-making."
"The stability is very good."
 

Cons

"The pricing for personal users is not cost-effective."
"You only receive one model in Proofpoint Email Protection and the other ones you have to purchase at a high price. There should be more available with the solution and additional models should be less expensive."
"Integration and filtering out who you want and don't want to have integrated ID could be improved."
"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."
"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."
"Phishing detection could improve further to match some of the capabilities offered by competitors."
"We'd like to have the ability to create more customized reports."
"It has too many screens. It is kind of a conglomeration of products. In other words, they built product A, product B, and product C, and they are yet to integrate them into a single administrative console. I would certainly like to see a more seamless administrative interface. I would also like to see them include more bang for the buck, by including features like email fraud protection, rather than making their product so piecemeal, where you are buying little pieces. I agree with the idea of having multiple tiers or layers, but maybe as small, medium, and large, as opposed to an a la carte menu."
"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."
 

Pricing and Cost Advice

Information not available
"Proofpoint Email Protection has comparable pricing."
"They are competitively priced, but I have been forced to get quotes for other solutions now because they haven't been responding to requests to do the work that we would like them to do."
"The price is reasonable."
"The licensing model for Proofpoint Email Protection is simple. It's based on the number of users. Price-wise, Proofpoint Email Protection is a five out of ten because it's a pretty expensive solution."
"Annually, it costs us about $92,000. This is pretty much what it costs us. There is no additional cost."
"The solution is expensive."
"We sell annual licenses for this solution."
"Pricing has recently been increased and the cost is a downside"
