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 solution scales well."
"The solution blocks malicious emails containing viruses and malware and reduces them out of spam."
"The initial implementation is pretty easy to handle."
"Proofpoint is the main tool for blocking spam because it denies the connection altogether."
"It's easy to use, even for those new to IT."
"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 archive feature is valuable."
"Compared to other products, Proofpoint's real-time threat intelligence makes it less noisy; they collect and share threat information effectively, which benefits all customers."
 

Cons

"The pricing for personal users is not cost-effective."
"I believe they still need to improve by consolidating some portals, as currently, you have to log in separately to a few of them."
"The setup requires expertise. It needs someone with experience on managing it, and I would rate the implementation as needing someone experienced."
"We'd like to have the ability to create more customized reports."
"The incident reporting on offer needs to be improved. It's lacking right now. It should be on the platform somewhere."
