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."
"It was easy to set up."
"The initial implementation is pretty easy to handle."
"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."
"Proofpoint Email Protection is stable enough and does its job of virus, malware, and email scam detection. Setting it up is not too complicated."
"I would recommend Proofpoint Email Protection to others because it is useful, simple to use, and provides whatever is required."
"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 setup was easy."
"It's very good at identifying threats."
 

Cons

"The pricing for personal users is not cost-effective."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"Proofpoint Email Protection could improve by allowing more customization of the reports, such as exceptions and black-and-white lists."
"Phishing detection could improve further to match some of the capabilities offered by competitors."
"In terms of improvement, the price could be better. Additionally, more security could be implemented."
"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."
"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."
"The price could be improved."
"The email DLP portion could be a bit easier."
