Email protection has reduced phishing workload and keeps unwanted messages out of inboxes
A few things about how Proofpoint Email Protection can be improved include implementing artificial intelligence within their platform to start really understanding the organization that is using their product, what sort of emails they are expecting and if the emails that are being expected should be let in and if the emails that are not being expected should not be let in. I'll give you a further example for this. If someone just tries to send an email from a Gmail address, which is a free public service email service provider, then because anyone in the world can create a Gmail account, I think it is nice and good for Proofpoint Email Protection to actually first check and do a reality check if we have received an email from this address and look at the intent of the email to really see what the email is trying to do and then classify based on that. I still see there is a lack. Hence why I started this conversation with AI and hoping that Proofpoint Email Protection will bring AI in and to really start analyzing these emails, the intent, and whether they really fit the customer organization. We are a manufacturing company, so whether it really fits that profile. I would say if we can get a better user experience from Proofpoint Email Protection products, that would be good. For example, other service providers that provide secure email gateway have the functionality where you can split promotional and bulk email and have them sent to a separate folder. I think if we can have that sort of feature, that would be great where Proofpoint Email Protection just keeps the important emails in the inbox folder and move everything else that is not really business related into a promotional, spam, bulk folder. This is an improvement that I would really like to see. I give it an eight because I am expecting a lot more from Proofpoint Email Protection, more automations, more understanding of who their customer is, what sort of business they do, and what sort of email they are supposed to be receiving and letting through. I think the day when I really have only 1% of work to do and 99% is automated by whatever automation services Proofpoint Email Protection uses would be ideal. I think I have covered any other improvements needed for Proofpoint Email Protection pretty well right from AI to splitting emails based on priorities. I think I have given some pretty broad and good examples.

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

"From a business perspective, the solution was very helpful as it speeded our business flow and increased email delivery."
"Proofpoint Email Protection has positively impacted my organization by advancing our email security posture."
"The most valuable features of Proofpoint Email Protection are ease of use, data loss prevention, antivirus, and spam protection."
"I recommend all of my customers to migrate and start using Proofpoint as it is secure, minimizes risk, and eliminates phishing attacks."
"The spam filter for email is good."
"I would recommend Proofpoint Email Protection to others because it is useful, simple to use, and provides whatever is required."
"When I manage a SOC and Proofpoint Email Protection is integrated with it, it gives me a consolidated alert, so when phishing alerts come in it is slightly easier to manage, even my L1 incident response team from the SOC can easily understand the alerts, perform basic checks on VirusTotal, and create complete SOAR automation from that information."
"Proofpoint Email Protection is stable enough and does its job of virus, malware, and email scam detection. Setting it up is not too complicated."
"I like its ability to detect and block."
"So far, I do not see any problem with Sublime Security's support or their customer service."
"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

"Sometimes it detects false positives."
"Pricing for the platform could still be cheaper."
"The largest complaint that we hear from our customers is that there is no local support."
"You only receive one model in Proofpoint Email Protection and the other ones you have to purchase at a high price. There should be more available with the solution and additional models should be less expensive."
"Proofpoint Email Protection has a new approach to email security with its API feature. Currently, it only works with Office 365. In the future, it would be beneficial if it also works with Gmail, as Check Point is currently the only brand that has API email security for Gmail. It would be beneficial if Proofpoint Email Protection could add this integration, they would be more competitive with other vendors."
"Given my other experience with other vendors, I think they are a bit on the high end and a bit on the pricey end for the email security functionality that we were using."
"Proofpoint Email Protection could improve by reducing the price."
"The flexibility of the solution can be improved."
"With Sublime Security, so far, I have seen a lot of false positives, and it is something that can bring a lot of administrative overhead."
"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."
"It is 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."
"The licensing is basically $8/user."
"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."
"In general, the pricing is competitive."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
