Email defenses have blocked advanced threats and provide deep visibility into risky users
The areas that have room for improvement in Proofpoint Email Protection include their cost of ownership, which is fairly high. To manage and run all their products, I have to list and manage administrators in seven or eight different places. That is too many places to keep track of since for this tool I have to go to one location, and for another tool I have to go to a different location. They need to simplify the administration management of administrators and consolidate that into one place for all their products. Access to all the different products is very scattered. For some products I go to one URL, and for different products I go to a different URL. They have a threat URL that has most of their products in it, but not all. They need to simplify the interface to show all the products I have access to in one location.

Manager Security Operations Center at a educational organization with 10,001+ employees
Improves decision-making with clear verdict explanations and works well across multiple environments
I know that a lot of time has been invested in improving the efficacy of the platform, and it shows; it performs very well. Moving forward, I think our focus should be on how to achieve better integration with other systems. 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. This would allow it to be integrated more closely with the workflows of various teams and could potentially increase its market appeal. From my perspective, the tool itself functions exceptionally well, which gives me confidence in the system. I want to see this functionality extend to other tools that I use, enabling faster automation and improved workflows for the team, particularly from a security operations standpoint. I have no critiques regarding the tool itself. They've done an outstanding job and are maintaining high quality throughout their development process. They have a great product, and it's essential that they continue to uphold that standard, even though it requires significant effort.

Quotes from Members

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

Pros

"The stability is very good."
"The solution's technical support is good. I rate the technical support a ten out of ten."
"They have customized security rules, mature rules, anti-virus protection, as well as email authentication similar to SPF, DKIM, and DMARC."
"The Tap and Trap features. They are the best features."
"The solution has very strong detection for most of the phishing and malicious emails received from the outside."
"Proofpoint provides an expandable project model, including DLP, email archiving, and encryption, which makes it a complete email security solution."
"Proofpoint Email Protection is the best solution from the perspective of email security."
"Proofpoint Email Protection has positively impacted my organization by advancing our email security posture."
"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 should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"Proofpoint has a lot of false alarms."
"Proofpoint Email Protection is an expensive solution."
"The solution should add post-sales training."
"It became very expensive due to the nature of local circumstances, and I may advise Proofpoint to adjust marketing solutions based on each country."
"It has too many screens. It is kind of a conglomeration of products. In other words, they built product A, product B, and product C, and they are yet to integrate them into a single administrative console. I would certainly like to see a more seamless administrative interface. I would also like to see them include more bang for the buck, by including features like email fraud protection, rather than making their product so piecemeal, where you are buying little pieces. I agree with the idea of having multiple tiers or layers, but maybe as small, medium, and large, as opposed to an a la carte menu."
"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."
"Proofpoint Email Protection does miss a lot of phishing attacks, and threat actors are using AI to create these phishing attacks."
"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

"The licensing model for Proofpoint Email Protection is simple. It's based on the number of users. Price-wise, Proofpoint Email Protection is a five out of ten because it's a pretty expensive solution."
"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"The solution is expensive."
"Clients pay for an annual subscription of Proofpoint Email Protection. Every client always finds it expensive."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"It is expensive."
"The licensing is basically $8/user."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
