Offers clear vision on the clear side of what is being blocked and easy to use but a bit old-fashioned GUI
I would rate my experience with the initial setup a four out of ten when one is difficult, and ten is easy. It's difficult initially since it's an on-premise solution. So it's a bit difficult. So the initial assessment took a few days, and then the deployment was a couple of days. It is on-prem. That is also one of the improvements you need to make on the cloud. Most of the people like things to be on the cloud. You don't have the burden of setting up things on-premise.

Email defenses have reduced phishing incidents and protect sensitive data across our enterprise
As things are evolving and threats develop in unpredictable ways, Proofpoint must adopt AI solutions and agentic solutions more aggressively and provide them to customers as part of service offerings. Inbuilt AI solutions would add more value and make Proofpoint a more premium choice for customers. With the help of AI solutions, agentic AI, and generative AI capabilities, the product would be more efficient than it currently is. Filtering false positives is highly challenging because it is impossible for humans to identify which emails are genuine and which are spam. Proofpoint should focus more on this area with back-end agents or other tools. Proofpoint should decide which emails are genuine and which are spam so it is not a challenge for end users. When receiving an email, end users should not have to determine whether to respond or not. Proofpoint should not release such spam emails and should strictly block such spam and spoof emails based on connection IPs. Currently, false positives occur in the product, and while this occurs in every product, it is an area where Proofpoint can focus on improving and reducing false positives. One email is enough for an end user to be deceived and lose money, so addressing this area is critical.

Quotes from Members

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

Pros

"The product's most valuable features are spam protection and artificial intelligence."
"I like that it doesn't hold emails for any reason; it sends out notifications to the user as well as administrators. So we have a clear vision on the clear side of what is being blocked and in time as well."
"On a day-to-day basis, Proofpoint Email Protection has saved me about 50% of my workload, which has been a real godsend."
"Using Proofpoint Email Protection has improved my SOC analyst workloads significantly by reducing false positives and the number of incidents in the queue."
"The most valuable feature of this solution is that it's a one-stop shop for email protection."
"Proofpoint Email Protection has positively impacted my organization by reducing the number of cyber email attacks we are receiving compared to the past."
"The solution offers very good flexibility. You can blacklist or whitelist with ease."
"Provides better control over emails, especially those sent via Office 365 on the cloud."
"The most valuable features of Proofpoint Email Protection are ease of use, data loss prevention, antivirus, and spam protection."
"The solution scales well."
 

Cons

"The technical support services and stability need improvement as well."
"There is room for improvement in GUI because it is a bit old-fashioned."
"I want Security Awareness Training in there as a package deal. A lot of companies are starting to value email security a little bit more and take it a little bit more seriously, and the great product that we link together with a lot of these sales is a training product called Security Awareness Training. It is an upsell that we do with Proofpoint, and it is definitely something that I recommend everybody with email security to look into. It would be great if Security Awareness Training is included with the email security."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"I believe they still need to improve by consolidating some portals, as currently, you have to log in separately to a few of them."
"As an enterprise, we have high demands on the services, and if we have to wait for something like a week or weeks, it is not acceptable; we need solutions in one or two days sometimes because if there is spam going around, you cannot wait weeks."
"The false positives are an issue. There are many false positives that come in, which you report to Proofpoint."
"Integration for reporting needs to be improved, it's a little complex."
"Integration and filtering out who you want and don't want to have integrated ID could be improved."
"If I had to pick one minor thing I would like to see improved in Proofpoint Email Protection, it would be integration with AutoTask or ConnectWise because I saw a few tickets where, when there is a notification on Proofpoint Email Protection, it takes a few minutes to maybe an hour to generate a ticket with ConnectWise and AutoTask."
 

Pricing and Cost Advice

"It is a cost-effective product."
"The pricing is in the middle. Compared to other products, it should be five out of ten, where one is cheap and ten is expensive."
"The end customer is buying our solution, which can be for monthly or annual usage depending on our payment and business model."
"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 solution is expensive."
"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."
"Pricing has recently been increased and the cost is a downside"
"I rate the price of Proofpoint Email Protection a four out of five."
"It is expensive."
