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.

A simple and easy-to-handle solution that does not need multiple configurations, but its pricing could be improved
Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations. A single IT admin supporting over 100 or 200 users can easily understand everyday reports. Trustifi Inbound Shield is a user-friendly solution that even simple lay people can understand. The product helps our customers avoid 95% of unwanted phishing emails.

Quotes from Members

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

Pros

"Proofpoint Email Protection is stable enough and does its job of virus, malware, and email scam detection. Setting it up is not too complicated."
"Proofpoint Email Protection is a strong and reliable solution for defending against advanced email threats, especially phishing and targeted attacks."
"The stability is good; there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
"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."
"The most valuable feature of Proofpoint Email Protection is the TAP Dashboard. It provides more detailed information that can be used for forensic analysis. This is an advantage that other email security providers, such as Cisco, IronPort, or Microsoft do not offer in their dashboards."
"I would recommend Proofpoint Email Protection to others because it is useful, simple to use, and provides whatever is required."
"Proofpoint Email Protection helped create a safe environment by blocking and preventing Active Directory harvesting attacks, imposter attacks, backscattering, spam, and malicious attacks."
"It has been comprehensive and easy to use for both users and administrators."
"Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations."
 

Cons

"I chose 9 out of 10 because it is based on the customization of exporting logs, and the user experience of the rule-based alerting and the portal is slightly lacking, which is why I deducted that one point."
"To move to a more sophisticated email security solution was cost-prohibitive. When you compare it to others, it was too expensive."
"The solution can be expensive."
"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"Proofpoint Email Protection does miss a lot of phishing attacks, and threat actors are using AI to create these phishing attacks."
"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."
"The areas that have room for improvement in Proofpoint Email Protection include their cost of ownership, which is fairly high."
"The downside is I feel the vendor support is a little lacking and should be more responsive."
"The solution's pricing is very high compared to other products like Barracuda and should be improved."
