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."
"I like all the features with Proofpoint, such as how it filters the spam and marketing mail, lost reality mail, blocks phishing attacks, blocks malicious attachments, and stops phishing links. Also it can defend against the business email compromise impersonation technique. It is a complete solution for all email attacks. It filters for the bad, malicious attachments. If there is any executable file, it can be deleted. It is a good, complete solution."
