Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

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

"Go for it! I think it's an excellent product with great technical support."
"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
"The solution has very strong detection for most of the phishing and malicious emails received from the outside."
"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."
"Proofpoint Email Protection offers an additional layer of protection compared to other brands like Microsoft, Mimecast, and Barracuda. While these major companies excel at detecting malicious attachments, the solution goes further by analyzing the context of emails, allowing for more nuanced decision-making."
"The targeted attack protection that we use has been great, as has the email filtering and the rules that we have set for Proofpoint."
"The solution scales quite well."
"Proofpoint Email Protection has increased the efficiency of the organization, as before a single end user might be receiving fifteen, twenty, or thirty spam emails in a week, but with Proofpoint Email Protection, they have decreased by approximately eighty percent, so users are receiving many fewer spam emails and do not have to go through all the spam emails just to verify if they are legitimate or not."
"I would recommend Proofpoint Email Protection to others because it is useful, simple to use, and provides whatever is required."
"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."
 

Cons

"I am not satisfied with Clearswift because of the lack of customer support."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"The solution should add post-sales training."
"The only limitation we have with Proofpoint Email Protection is when we implement it with Google Workspace."
"The false positives are an issue. There are many false positives that come in, which you report to Proofpoint."
"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."
"As far as visibility goes, it is definitely attainable, but additional appliances must be purchased for Proofpoint. I would rate visibility at approximately 50 to 60 percent."
"Proofpoint is a little bit expensive."
"I rate the technical support at a 3 out of 10, with 10 being the best."
"Proofpoint has a lot of false alarms. Even their mail flow rules are not the best thing."
 

Pricing and Cost Advice

Information not available
"In general, the pricing is competitive."
"It is multiple times more expensive, which made it very much less attractive."
"Pricing has recently been increased and the cost is a downside"
"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."
"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."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"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."
"Proofpoint is fairly expensive."
