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."
"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."
"Proofpoint Email Protection has positively impacted my organization by ensuring we are not at risk of a breach through email."
"I like all the features with Proofpoint, such as how it filters the spam and marketing mail, lost reality mail, blocks phishing attacks, blocks malicious attachments, and stops phishing links. Also it can defend against the business email compromise impersonation technique. It is a complete solution for all email attacks. It filters for the bad, malicious attachments. If there is any executable file, it can be deleted. It is a good, complete solution."
"Using Proofpoint Email Protection has improved my SOC analyst workloads significantly by reducing false positives and the number of incidents in the queue."
"Proofpoint Email Protection has positively impacted our organization as it has been deployed for more than five years, serving as a good SEG that protects our staff members before email hits their inboxes and filters out junk or spam, allowing users to spend significantly more time on real work rather than going through unnecessary emails."
"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."
"At this point in time, there's nothing that needs to be changed or improved in the tool."
"The stability is good; there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
"Proofpoint Email Protection is a strong and reliable solution for defending against advanced email threats, especially phishing and targeted attacks."
 

Cons

"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"I am not satisfied with Clearswift because of the lack of customer support."
"I think Proofpoint Email Protection could be slightly more intuitive."
"To move to a more sophisticated email security solution was cost-prohibitive. When you compare it to others, it was too expensive."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"As mentioned on the Proofpoint website, it blocks almost around 99.99%, but as far as the last six months of data which we have analyzed, it is slightly on the lower side, around 97 to 98%."
"There is room for improvement in detecting and preventing phishing attacks. While the solution performs well in some aspects, it struggles with phishing threats."
"Proofpoint Email Protection can be improved by using more AI-powered features."
"I rate the technical support at a 3 out of 10, with 10 being the best."
"The areas that have room for improvement in Proofpoint Email Protection include their cost of ownership, which is fairly high."
