Email protection has reduced phishing workload and keeps unwanted messages out of inboxes
A few things about how Proofpoint Email Protection can be improved include implementing artificial intelligence within their platform to start really understanding the organization that is using their product, what sort of emails they are expecting and if the emails that are being expected should be let in and if the emails that are not being expected should not be let in. I'll give you a further example for this. If someone just tries to send an email from a Gmail address, which is a free public service email service provider, then because anyone in the world can create a Gmail account, I think it is nice and good for Proofpoint Email Protection to actually first check and do a reality check if we have received an email from this address and look at the intent of the email to really see what the email is trying to do and then classify based on that. I still see there is a lack. Hence why I started this conversation with AI and hoping that Proofpoint Email Protection will bring AI in and to really start analyzing these emails, the intent, and whether they really fit the customer organization. We are a manufacturing company, so whether it really fits that profile. I would say if we can get a better user experience from Proofpoint Email Protection products, that would be good. For example, other service providers that provide secure email gateway have the functionality where you can split promotional and bulk email and have them sent to a separate folder. I think if we can have that sort of feature, that would be great where Proofpoint Email Protection just keeps the important emails in the inbox folder and move everything else that is not really business related into a promotional, spam, bulk folder. This is an improvement that I would really like to see. I give it an eight because I am expecting a lot more from Proofpoint Email Protection, more automations, more understanding of who their customer is, what sort of business they do, and what sort of email they are supposed to be receiving and letting through. I think the day when I really have only 1% of work to do and 99% is automated by whatever automation services Proofpoint Email Protection uses would be ideal. I think I have covered any other improvements needed for Proofpoint Email Protection pretty well right from AI to splitting emails based on priorities. I think I have given some pretty broad and good examples.

Quotes from Members

Cons
