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 most valuable feature is the option to edit the inbound security."
"Proofpoint provides an expandable project model, including DLP, email archiving, and encryption, which makes it a complete email security solution."
"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."
"It is a very scalable solution."
"The solution scales well."
"The solution has very strong detection for most of the phishing and malicious emails received from the outside."
"The spam filter for email is good."
"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."
"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

"Proofpoint Email Protection could improve by reducing the price."
"Proofpoint Email Protection could improve by allowing more customization of the reports, such as exceptions and black-and-white lists."
"Proofpoint Email Protection's interface is confusing and could be improved."
"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."
"The support team was a bit slow."
"Proofpoint Email Protection could improve the Mail Trace feature and make navigation easier."
"They do not have an on-demand scan for the internal viruses and internal users, and they don't have a scan for the exchange server against viruses and spam as Symantec does."
"Sometimes it doesn't detect actual spam emails, and sometimes it catches normal emails."
"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."
"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."
 

Pricing and Cost Advice

"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."
"Clients pay for an annual subscription of Proofpoint Email Protection. Every client always finds it expensive."
"The price is reasonable."
"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"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 rate the price of Proofpoint Email Protection a four out of five."
"The solution charges per user per month to use it. There are not any additional fees in addition to the standard living fees."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
