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

"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."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
"Go for it! I think it's an excellent product with great technical support."
"Proofpoint is number one in terms of market share worldwide, and we recommend it to clients because of its rich features in email protection, cloud protection, and backup targeted attack protection."
"URL scanning and online relay service are the most valuable features of Proofpoint Email Protection."
"The most valuable feature is the option to edit the inbound security."
"The stability is very good."
"From a business perspective, the solution was very helpful as it speeded our business flow and increased email delivery."
"Proofpoint Email Protection is very effective because they are very proactive, always ahead of the attackers, and were already detecting new kinds of attacks before customers thought about them."
"Proofpoint Email Protection has positively impacted my organization by ensuring we are not at risk of a breach through email."
"The solution scales quite well."
 

Cons

"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"I am not satisfied with Clearswift because of the lack of customer support."
"The only limitation we have with Proofpoint Email Protection is when we implement it with Google Workspace."
"One major threat is QR code phishing, along with TOAD (Telephone-Oriented Attack Delivery). TOAD attacks don't include links, URLs, or attachments in emails. Instead, attackers try to trick you into calling them, often by offering something enticing like a 50% discount on football matches."
"Integration for reporting needs to be improved, it's a little complex."
"I think Proofpoint Email Protection could be slightly more intuitive."
"The downside is I feel the vendor support is a little lacking and should be more responsive."
"The areas that have room for improvement in Proofpoint Email Protection include their cost of ownership, which is fairly high."
"The false positives are an issue. There are many false positives that come in, which you report to Proofpoint."
"I think Proofpoint Email Protection could be improved if the user interface portals could be consolidated into a single portal, as there are currently four, five, or six separate ones."
