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.

A simple and easy-to-handle solution that does not need multiple configurations, but its pricing could be improved
Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations. A single IT admin supporting over 100 or 200 users can easily understand everyday reports. Trustifi Inbound Shield is a user-friendly solution that even simple lay people can understand. The product helps our customers avoid 95% of unwanted phishing emails.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is the option to edit the inbound security."
"The Phish Alarm button allows users to submit questionable emails for review and complete analysis."
"The most valuable features of Proofpoint Email Protection are ease of use, data loss prevention, antivirus, and spam protection."
"From a business perspective, the solution was very helpful as it speeded our business flow and increased email delivery."
"That is why I can consider Proofpoint Email Protection as a number one vendor for email security."
"The Tap and Trap features. They are the best features."
"It's a mature product. It does a good job in detection."
"The anti-spam features are excellent on the email firewalls."
"Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations."
 

Cons

"The solution should add post-sales training."
"Integration for reporting needs to be improved, it's too complex."
"The accessibility of Proofpoint Email Protection, particularly access to product trials, could be improved. It's hard to get a trial for Proofpoint Email Protection, and many customers prefer not just to do the POC or demo but try the product out."
"Proofpoint Email Protection could improve on the training. Every organization is different and to fine-tune it to block everything properly there needs to be better training. Sometimes it can block some of the information it shouldn't."
"The support team was a bit slow."
"It became very expensive due to the nature of local circumstances, and I may advise Proofpoint to adjust marketing solutions based on each country."
"One major threat is QR code phishing, along with TOAD (Telephone-Oriented Attack Delivery). TOAD attacks don't include links, URLs, or attachments in emails. Instead, attackers try to trick you into calling them, often by offering something enticing like a 50% discount on football matches."
"The scalability can be improved, and the solution can be optimized."
"The solution's pricing is very high compared to other products like Barracuda and should be improved."
 

Pricing and Cost Advice

"Clients pay for an annual subscription of Proofpoint Email Protection. Every client always finds it expensive."
"The solution is expensive."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"They are competitively priced, but I have been forced to get quotes for other solutions now because they haven't been responding to requests to do the work that we would like them to do."
"The price is reasonable."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"Proofpoint Email Protection has comparable pricing."
"Customers pay around $90,000 yearly for a 1,000-user organization, with the subscription license being the main expense, apart from implementation fees."
