Has provided reliable threat detection and simplified policy management
I do not have experience with Microsoft Purview products, but I know some Proofpoint products. I apologize, I do not have experience with the Purview one, but I do know the Proofpoint products. I'm not sure about the features of the Purview one. 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. I have seen a lot of improvements in Proofpoint's reporting and analytics compared to earlier days. As a leader in the market, I find the pricing for Proofpoint Email Protection is a little high. Their licensing models vary, and even the premium model adequately supports awareness campaigning, so I find it acceptable. Normally, they sell their products through resellers, not directly through AWS Marketplace. For us, we are clients of Proofpoint. I rate Proofpoint Email Protection a nine out of ten.

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

"It was easy to set up."
"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."
"Proofpoint provides an expandable project model, including DLP, email archiving, and encryption, which makes it a complete email security solution."
"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."
"It's detection of true positives are great, as it's cloud based it's very scalable and stable."
"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."
"It's very good at identifying threats."
"The solution has very strong detection for most of the phishing and malicious emails received from the outside."
"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."
"I like its ability to detect and block."
 

Cons

"Pricing for the platform could still be cheaper."
"We find the cost to be prohibitive."
"Sometimes it detects false positives."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"Integration and filtering out who you want and don't want to have integrated ID could be improved."
"It became very expensive due to the nature of local circumstances, and I may advise Proofpoint to adjust marketing solutions based on each country."
"Integration for reporting needs to be improved, it's too complex."
"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 cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"Annually, it costs us about $92,000. This is pretty much what it costs us. There is no additional cost."
"The price is reasonable."
"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."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"Clients pay for an annual subscription of Proofpoint Email Protection. Every client always finds it expensive."
"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."
"It is multiple times more expensive, which made it very much less attractive."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
