Optimize email security with effective sandboxing and auto Pull for quarantine
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

"Proofpoint is the main tool for blocking spam because it denies the connection altogether."
"They have customized security rules, mature rules, anti-virus protection, as well as email authentication similar to SPF, DKIM, and DMARC."
"Proofpoint Email Protection is a good product, and its most beneficial feature is the Threat Response Auto-Pull. I also like that it's an integrated email security solution."
"The most valuable feature is the ability to remove bad messages that were delivered, prior to being classified as unwanted."
"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."
"As a cloud-based product, it can scale well."
"Proofpoint Email Protection is the best solution from the perspective of email security."
"It's the top choice because no company can operate without security. Ensuring email protection is a major priority for any organization when building its infrastructure."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"Trend Micro is a very good product."
"I like that it is very user-friendly and easy to install."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."
"I find Trend Micro to be a good solution for security purposes."
"I would rate the solution's stability at ten out of ten."
"It can effectively monitor outbound and inbound devices."

Cons

"Proofpoint Email Protection is an expensive solution."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"The reporting section could be enhanced. I like some reports but if they could allow us to create custom reports with more flexibility it would enhance the reports more."
"Pricing for the platform could still be cheaper."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"We'd like to have the ability to create more customized reports."
"The solution should add post-sales training."
"The high cost of the product is an area of concern where improvements are required."
"I would like to be able to send emails to a specific sandbox. This is a feature I would like to see added to the next release."
"It could be more user-friendly, easier to install, and lighter on the network. I would say that for all products because you do not need technical expertise to take care of it. When you have a user-friendly solution, it makes it easier for the vendors or companies like us. We do not have to go to the client's site to attend to issues all the time. Because it is user-friendly, they can take care of it after some training."
"To improve Trend Micro Deep Discovery Email Inspector, it should have updates with better AI and ML-based integration."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."
"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"The tool needs to incorporate faster response times for issue detection, more detailed reports, and better compatibility with older operating systems (e.g., Windows 7, 8, Server 2012)."
"Trend Micro's technical support has room for improvement."
