Secures email by identifying threats and managing email policies effectively
The intuitive management interface feature makes email security policies very easy to implement as it's all about features that need to be enabled or disabled. Our investigation in any incident or mail is very useful as it provides all details about incoming mails, enabling thorough review and detection. The real-time threat intelligence feature is particularly useful as it detects all kinds of threats identified by incoming mails. The Impersonation license utilizes AI tools. Sometimes some phishing mails are reported as phishing, but they are not actually phishing mails. They are detected due to certain words and languages that appear suspicious but were generated by AI tools. Everyone or an advisor may use it for their own purpose or learning, even though it indicates that the mail detected is phishing when it's not.

Advanced email protection has blocked targeted attacks and reduces manual threat handling
I feel Proofpoint Email Protection is overpriced. I cannot say that the security level being provided does not justify the cost, but when comparing the similar level of security with other applications or security systems, it is overpriced. If Proofpoint could provide offers or discounts for customers who are already using the product or for new customers implementing it, along with some free services or add-ons, that would be helpful in terms of financial expense. Proofpoint Email Protection has recently introduced AI functionality in terms of data security capabilities and protecting AI assistance from targeted attacks. This is important since everything is now related to AI. The solution is doing threat detection and real-time threat detection and response pretty well. There are a few things I would like to see improved. Sometimes Proofpoint Email Protection takes time to analyze the workflow and the nature of the email. In this age of AI, the solution should analyze an email on the first receipt and determine whether it should pass or be marked as spam without checking previous data. Another improvement would be to have a more user-friendly dashboard. Additionally, if Proofpoint could add the same features in BCP as part of email protection in BCP, it would be helpful since I currently have to take a different add-on for BCP, and integrating it would save costs. I cannot say that threats have increased or decreased with Proofpoint Email Protection because it depends on the mail flow. The solution captures and filters out all threats, and the email threats vary every day depending on how many users are receiving how many emails per day. Today there might be 1,000 emails, tomorrow 5,000, and the day after 500. Proofpoint Email Protection does its job by scanning all emails and threats are reduced to some extent. Since I am aware that virus definitions are updated every day, I cannot blame Proofpoint Email Protection if they take time to determine the nature of an email being received. There are sometimes emails that are false positives, and Proofpoint Email Protection is a bit strict in analyzing false positives, sometimes stopping emails that are actually required. It analyzes the previous nature of an email and if a template looks like an informational template or related to spam, it blocks it because it looks similar to one blocked earlier. However, the template might actually be required. If I receive the same template today that is also blocked by Proofpoint Email Protection, that particular template might be useful and should not be blocked. In such cases, I have to raise it as a false positive stating that this is something in use or my users use and should be released. When AI starts doing its work, it analyzes the email from a sender with a particular template and releases it, but if the same email and template come from another sender, it blocks it according to the policies.
