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

"At this point in time, there's nothing that needs to be changed or improved in the tool."
"The most valuable feature is the ability to remove bad messages that were delivered, prior to being classified as unwanted."
"Proofpoint Email Protection provides quite comprehensive protection."
"It is a very scalable solution."
"The stability is good; there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
"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."
"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."
"It's the top choice because no company can operate without security. Ensuring email protection is a major priority for any organization when building its infrastructure."
"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

"To improve Proofpoint Email Protection, I suggest improving the UI from the pod to align with the new admin.proofpoint.com interface, as the pod is still existing for a reason, but the interface is definitely outdated."
"The largest complaint that we hear from our customers is that there is no local support."
"We have some use cases that haven't been dealt with yet, so that could be improved."
"It can be improved pricing-wise so that it is affordable for the SMB market."
"It became very expensive due to the nature of local circumstances, and I may advise Proofpoint to adjust marketing solutions based on each country."
"The solution could be improved with the addition of PLP and email encryption features."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"We have seen a reduction in phishing incidents with Proofpoint Email Protection, but not fully; it is not 100%, and there are still cracks within the walls of Proofpoint Email Protection that let this type of email in for various reasons."
"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

"I rate the price of Proofpoint Email Protection a four out of five."
"It is on a yearly basis. Their floor for SMB doesn't matter. The user count is 100 users and below at $2,500 a year. Its cost is higher than other solutions. It is probably about 20% to 30% higher than what you would get with Microsoft. There are no additional costs. All costs are factored in. It can be improved pricing-wise so that it is affordable for the SMB market."
"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 end customer is buying our solution, which can be for monthly or annual usage depending on our payment and business model."
"It is multiple times more expensive, which made it very much less attractive."
"The licensing is basically $8/user."
"Customers pay around $90,000 yearly for a 1,000-user organization, with the subscription license being the main expense, apart from implementation fees."
"Clients pay for an annual subscription of Proofpoint Email Protection. Every client always finds it expensive."
