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.

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

"Its main defense is to stop malicious emails from coming through. There is a sandbox environment where you can open malicious or suspicious emails to make sure that they're not malicious, instead of taking the risk of having your employees do it. This is definitely something that everybody needs nowadays, especially with the rise in cyber attacks."
"Proofpoint Email Protection has positively impacted my organization by ensuring we are not at risk of a breach through email."
"Its anti-phishing functionality is the most valuable. Certainly, the biggest problem I have is phishing."
"I like all the features with Proofpoint, such as how it filters the spam and marketing mail, lost reality mail, blocks phishing attacks, blocks malicious attachments, and stops phishing links. Also it can defend against the business email compromise impersonation technique. It is a complete solution for all email attacks. It filters for the bad, malicious attachments. If there is any executable file, it can be deleted. It is a good, complete solution."
"From a mail gateway perspective, I think Proofpoint Email Protection is one of the most complete options compared to others."
"Proofpoint Email Protection has definitely impacted my organization positively."
"A lot of automation is present, and the quarantining of malicious emails and these processes are good and really help us in the investigation as well as the remediation part."
"The most valuable features of Proofpoint Email Protection are the performance from being on the cloud."
"Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations."
 

Cons

"Proofpoint Email Protection can be improved in that it is quite a large product, so learning how to be fully conversant in it can take some time within the team; this is probably the biggest challenge at the moment for us, getting everyone fully conversant to support the product."
"While ingesting the logs into our SIEM tool, most organizations don't have the capability to buy the email gateway as it is quite an expensive one."
"The disadvantage of Proofpoint Email Protection in comparison to other competitors is its cost."
"Proofpoint has a lot of false alarms. Even their mail flow rules are not the best thing."
"The downside is I feel the vendor support is a little lacking and should be more responsive."
"The false positives are an issue. There are many false positives that come in, which you report to Proofpoint."
"The email DLP portion could be a bit easier."
"Phishing detection could improve further to match some of the capabilities offered by competitors."
"The solution's pricing is very high compared to other products like Barracuda and should be improved."
 

Pricing and Cost Advice

"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"We sell annual licenses for this solution."
"Customers pay around $90,000 yearly for a 1,000-user organization, with the subscription license being the main expense, apart from implementation fees."
"It is on a yearly basis. Their floor for SMB doesn't matter. The user count is 100 users and below at $2,500 a year. Its cost is higher than other solutions. It is probably about 20% to 30% higher than what you would get with Microsoft. There are no additional costs. All costs are factored in. It can be improved pricing-wise so that it is affordable for the SMB market."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"In general, the pricing is competitive."
"It is multiple times more expensive, which made it very much less attractive."
