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 ease of use, data loss prevention, antivirus, and spam protection."
"The most valuable feature of Proofpoint Email Protection is the TAP Dashboard. It provides more detailed information that can be used for forensic analysis. This is an advantage that other email security providers, such as Cisco, IronPort, or Microsoft do not offer in their dashboards."
"Proofpoint provides an expandable project model, including DLP, email archiving, and encryption, which makes it a complete email security solution."
"I recommend all of my customers to migrate and start using Proofpoint as it is secure, minimizes risk, and eliminates phishing attacks."
"The most valuable feature is the option to edit the inbound security."
"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 initial implementation is pretty easy to handle."
"The Tap and Trap features. They are the best features."
 

Cons

"The pricing for personal users is not cost-effective."
"I would want better spear phishing protection in the essentials package."
"Proofpoint Email Protection could improve by allowing more customization of the reports, such as exceptions and black-and-white lists."
"The product's deployment is complex and requires technical knowledge."
"Proofpoint Email Protection could improve by reducing the price."
"The initial setup is complex."
"I want Security Awareness Training in there as a package deal. A lot of companies are starting to value email security a little bit more and take it a little bit more seriously, and the great product that we link together with a lot of these sales is a training product called Security Awareness Training. It is an upsell that we do with Proofpoint, and it is definitely something that I recommend everybody with email security to look into. It would be great if Security Awareness Training is included with the email security."
"There is room for improvement in detecting and preventing phishing attacks. While the solution performs well in some aspects, it struggles with phishing threats."
"Proofpoint has a lot of false alarms."
