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…
LARK IT - PeerSpot reviewer
Easy to setup, stable and highly scalable
The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through. In future releases, I would just like to see that ability for users to see what's being quarantined and what's not quarantined but safe. Just those genuine false positives.

Quotes from Members

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

Pros

"The setup was easy."
"The most valuable feature of Proofpoint Email Protection is the dashboards and their visibility, easy configuration, and artificial intelligence. Additionally, the reports are very important and helpful."
"It's very good at identifying threats."
"Provides better control over emails, especially those sent via Office 365 on the cloud."
"The stability is very good."
"The solution scales well."
"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 features of Proofpoint Email Protection are ease of use, data loss prevention, antivirus, and spam protection."
"I like its ability to detect and block."
"Overall, the auditability and the ability to evaluate the information in Sublime through various mechanisms made me very comfortable with setting these capabilities to auto-remediation."
 

Cons

"The solution's server console and cluster dashboard have been the same for four years so need to be upgraded."
"Proofpoint Email Protection is an expensive solution."
"We'd like to have the ability to create more customized reports."
"The product's deployment is complex and requires technical knowledge."
"It's scalable, but the devil's in the details — you have to know your email volumes."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"There is room for improvement in detecting and preventing phishing attacks. While the solution performs well in some aspects, it struggles with phishing threats."
"Integration and filtering out who you want and don't want to have integrated ID could be improved."
"The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through."
"While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value."
 

Pricing and Cost Advice

"Pricing has recently been increased and the cost is a downside"
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"They are competitively priced, but I have been forced to get quotes for other solutions now because they haven't been responding to requests to do the work that we would like them to do."
"In general, the pricing is competitive."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"The price is reasonable."
"The solution uses a licensing model that is reasonable compared to other products."
"It is on a yearly basis. Their floor for SMB doesn't matter. The user count is 100 users and below at $2,500 a year. Its cost is higher than other solutions. It is probably about 20% to 30% higher than what you would get with Microsoft. There are no additional costs. All costs are factored in. It can be improved pricing-wise so that it is affordable for the SMB market."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
