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 most important feature is data processing."
"The most important feature is data processing, and I like the dashboard and the undo or multi-call feature of Microsoft Purview Customer Lockbox."
"The spam filter for email is good."
"The solution is very user-friendly."
"As a cloud-based product, it can scale well."
"The setup was easy."
"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."
"Proofpoint Email Protection has increased the efficiency of the organization, as before a single end user might be receiving fifteen, twenty, or thirty spam emails in a week, but with Proofpoint Email Protection, they have decreased by approximately eighty percent, so users are receiving many fewer spam emails and do not have to go through all the spam emails just to verify if they are legitimate or not."
"Proofpoint Email Protection has reduced the analyst overhead in responding to phishing incidents by several orders of magnitude."
"On a day-to-day basis, Proofpoint Email Protection has saved me about 50% of my workload, which has been a real godsend."
 

Cons

"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."
"It became very expensive due to the nature of local circumstances, and I may advise Proofpoint to adjust marketing solutions based on each country."
"We'd like to have the ability to create more customized reports."
"I think Proofpoint Email Protection could be slightly more intuitive."
