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

"The Phish Alarm button allows users to submit questionable emails for review and complete analysis."
"Proofpoint Email Protection has positively impacted my overall security posture, making it easier for users to encrypt files right in the portal and send them to customers, and it is simple for customers to access those files without difficulty."
"A lot of automation is present, and the quarantining of malicious emails and these processes are good and really help us in the investigation as well as the remediation part."
"From a business perspective, the solution was very helpful as it speeded our business flow and increased email delivery."
"Using Proofpoint Email Protection significantly reduces the number of threats I need to guard against; within a month, my organization sends and receives over 1 million emails, achieving 99.99% protection against phishing and spam, and handling around 5 to 10 million emails monthly while assigning a project manager for ongoing review."
"From a mail gateway perspective, I think Proofpoint Email Protection is one of the most complete options compared to others."
"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."
"Proofpoint Email Protection's initial installation is straightforward. It took us less than a day to complete the implementation."
"The feature I found most valuable was getting details on the emails, being alerted once those emails got a bad reputation, and then being able to take action on those emails."
 

Cons

"The solution could be improved with the addition of PLP and email encryption features."
"In terms of improvement, the price could be better. Additionally, more security could be implemented."
"The flexibility of the solution can be improved."
"Regarding improvements, the search in Proofpoint Email Protection is a bit slow sometimes; if it was quicker, it could probably improve the search a little bit."
"It's scalable, but the devil's in the details — you have to know your email volumes."
"Some of the old portal features of Proofpoint Email Protection are missing in the new portal, so some of the settings could be modernized."
"Proofpoint Email Protection's interface is confusing and could be improved."
"I feel Proofpoint Email Protection can be improved by providing a better user experience."
"This solution needs to improve the area of GUI as well as dashboards because they are very poor in terms of the current email security solution."
 

Pricing and Cost Advice

"The licensing is basically $8/user."
"Pricing has recently been increased and the cost is a downside"
"Proofpoint Email Protection has comparable pricing."
"We sell annual licenses for this solution."
"The solution charges per user per month to use it. There are not any additional fees in addition to the standard living fees."
"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."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"The tool's pricing depends on the customer's preference, offering options for an annual license or a monthly subscription. The cost varies based on factors such as the number of users and specific requirements. Overall, the pricing is competitive."
