Offers clear vision on the clear side of what is being blocked and easy to use but a bit old-fashioned GUI
I would rate my experience with the initial setup a four out of ten when one is difficult, and ten is easy. It's difficult initially since it's an on-premise solution. So it's a bit difficult. So the initial assessment took a few days, and then the deployment was a couple of days. It is on-prem. That is also one of the improvements you need to make on the cloud. Most of the people like things to be on the cloud. You don't have the burden of setting up things on-premise.

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.
