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."
"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"Go for it! I think it's an excellent product with great technical support."
"Its main defense is to stop malicious emails from coming through. There is a sandbox environment where you can open malicious or suspicious emails to make sure that they're not malicious, instead of taking the risk of having your employees do it. This is definitely something that everybody needs nowadays, especially with the rise in cyber attacks."
"Proofpoint Email Protection has massively improved the attack surface and has limited a lot of user compromise events."
"The anti-spam features are excellent on the email firewalls."
"Although it is a bit costly compared to Mimecast, Defender, and Cofense Vision, it is efficient and strong in security, so I do not mind the cost because I will not reduce my security risk."
"Proofpoint Email Protection provides visibility into people-based risk within my organization, and I am able to see which users have a higher risk rate."
"It's one of the top products out there."
"A one-stop shop for email protection"
"As a cloud-based product, it can scale well."
 

Cons

"Malware needs improvement."
"I am not satisfied with Clearswift because of the lack of customer support."
"FTP server and TRUST Manager functionality."
"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."
"However, for the cons, it requires continuous policy tuning to manage false positives. A Proofpoint Email Protection engineer requires continuous policy tuning to manage false positives, which is a disadvantage."
"The downside is I feel the vendor support is a little lacking and should be more responsive."
"We find the cost to be prohibitive."
"For Proofpoint Email Protection, when it comes to support, there are times when they do not meet the SLAs for support, mostly on Fridays."
"Proofpoint Email Protection needs to enhance its capabilities for AI-related threats as it is primarily a rule-based solution."
"The areas of Proofpoint Email Protection that could be improved or enhanced involve the email rewrite functionality. It can be aggressive sometimes, rewriting a lot of very benign content."
