Proofpoint is used as an email security gateway for big enterprises, primarily for their on-premises servers. Many customers also use it alongside Office 365 Proofpoint offers a complete solution for email security with features like DLP, email archiving, and encryption. The most valuable…
Bilal Saleem - PeerSpot reviewer
Reliability and threat intelligence make this solution competitive, but AI improvements can further enhance its effectiveness
The best features of Trend Micro Deep Discovery Email Inspector include its reliability. The second valuable feature is its built-in sandbox feature, allowing for inspection of incoming emails and attachments. The sandbox is an appliance that opens any attachment in an enclosed environment to assess its impact and potential for viruses. This protects the network from harmful threats. Trend Micro has a very large R&D team with excellent threat intel, allowing them to provide better solutions than some competitors. They understand emerging threats based on the information from their EDR. The key strengths can be summarized as reliability, a good integrated one-box solution that includes a sandbox, and their R&D capabilities and good ratings, which lead to better threat intelligence. The detailed threat intelligence provided by Trend Micro Deep Discovery Email Inspector is valuable in understanding the behavior and tactics of potential email threats.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It's very good at identifying threats."
"It is a very scalable solution."
"Its anti-phishing functionality is the most valuable. Certainly, the biggest problem I have is phishing."

"Provides better control over emails, especially those sent via Office 365 on the cloud."
"The most valuable feature of Proofpoint Email Protection is the central location dashboard for viewing all the related information for risk."
"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."
"Its main defense is to stop malicious emails from coming through. There is a sandbox environment where you can open malicious or suspicious emails to make sure that they're not malicious, instead of taking the risk of having your employees do it. This is definitely something that everybody needs nowadays, especially with the rise in cyber attacks."

"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."

"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
