Cyber Security Senior Specialist at a tech vendor with 10,001+ employees
Advanced email defenses have protected healthcare staff and simplified incident response
There are many things that could be improved, but once you are very well-known about this application, you could perform that improvement plan. There are many scenarios where I have worked with Proofpoint Email Protection where a requirement was not fulfilled due to the limitation of the product. For example, we have Report Phish automation. With Proofpoint Email Protection, we can configure Report Phish and forward the email to any email addresses or shared mailboxes that we provide in the configuration. That email is forwarded as is with whatever the user reports as a phishing email. However, some organizations do not want the reported phishing email to go as is into their ticketing tool because it might contain malicious attachments and malicious links that are not required to go into their internal organization. Proofpoint Email Protection has that limitation. They cannot forward or restrict, but could forward only limited information such as some header information, sender subject details, or only limited information. As it is, the email can be forwarded, not as limited information. Proofpoint TRAP solution also has limitations. It cannot create alert notifications for some specific requirements because Proofpoint works the way it is designed, and if you want it to work based on our requirement, that should not be possible. There is a scope of limitations here. There are many improvements that should be made. First, they should work on their false positive minimization. Proofpoint generally takes all emails, investigates them, and classifies them. There are many situations where legit emails are blocked because that domain is found to be under a malicious category somehow, but actually it is not. False positive minimization could be improved, and they could enhance their other applications or solutions. There are many things that they could improve from each application and each portal.

Threat detection has improved for zero‑day attacks but alert noise and support still need work
There are many ways Trellix Network Detection and Response can be improved. Trellix Network Detection and Response needs to reduce the alert noise because even after a lot of filtering, there is still a lot of noise which needs to be tuned by the industry vertical. Trellix Network Detection and Response needs to deepen the cloud-native support with parity between on-premises and cloud deployments. Trellix Network Detection and Response needs to improve threat intelligence depth as Trellix Network Detection and Response is not known to have the best signatures or the AI-supported intelligence that competitors may have. Trellix Network Detection and Response also needs revamped documentation because we had a lot of issues trying to find the syntaxes for all the rule-making. We had to search a lot and Trellix Network Detection and Response does not really help with their documentation, as it only covers basic information. The customer service is not that good. Trellix Network Detection and Response needs accelerated customer support to reach out to the top-level heads. Most of the time we are just stuck at the ground level talking to their customer support team, and they are not able to help us because we usually need to connect with the engineering team to help us out with the specifics.
