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.
Dennis O'Reilly - PeerSpot reviewer
Cyber SecOps Principal at Dotcom Security
The product provides good content filtering options, but the false positive submissions must be improved
The tool is very stable. I rate the stability a seven out of ten. It's an on-premise application that runs on a virtual machine. It has dependencies on the hypervisor host that we're running it on. If it's not configured, the application can be influenced by it. Sometimes, there is a service stop error while the service is still running. Sometimes, the service just stops. Some policies do not act the way that we intend them to respond.

Quotes from Members

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

Pros

"Proofpoint Email Protection helped create a safe environment by blocking and preventing Active Directory harvesting attacks, imposter attacks, backscattering, spam, and malicious attacks."
"Its anti-phishing functionality is the most valuable. Certainly, the biggest problem I have is phishing."
"Proofpoint Email Protection offers an additional layer of protection compared to other brands like Microsoft, Mimecast, and Barracuda. While these major companies excel at detecting malicious attachments, the solution goes further by analyzing the context of emails, allowing for more nuanced decision-making."
"The initial implementation is pretty easy to handle."
"The most valuable feature of Proofpoint Email Protection is the central location dashboard for viewing all the related information for risk."
"The anti-spam features are excellent on the email firewalls."
"Proofpoint Email Protection is quite scalable; I have not experienced any issues with the onboarding and offboarding of users and devices."
"They have customized security rules, mature rules, anti-virus protection, as well as email authentication similar to SPF, DKIM, and DMARC."
"Symantec Messaging Gateway has a good GUI, and it is very powerful in detecting viruses and spam."
"I like that it's simple and easy to configure, deploy, and manage. The reporting function has all the features we're looking for, and we are fine with that."
"The solution is stable and the performance is good."
"The solution is a leader in anti-spam email products and you can block 99% of spam emails, making it very effective with great performance."
"The solution is excellent at blocking spam."
"The most valuable features of Symantec Messaging Gateway are advanced content filtering, malware, and antivirus defense."
"The main thing that I appreciate about this product is that the database of spam, malware, and ransomware is very large."
"We use the solution for its advanced virus protection, phishing and other features."
 

Cons

"Proofpoint Email Protection does miss a lot of phishing attacks, and threat actors are using AI to create these phishing attacks."
"It can be improved pricing-wise so that it is affordable for the SMB market."
"Given my other experience with other vendors, I think they are a bit on the high end and a bit on the pricey end for the email security functionality that we were using."
"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"To improve Proofpoint Email Protection, I suggest improving the UI from the pod to align with the new admin.proofpoint.com interface, as the pod is still existing for a reason, but the interface is definitely outdated."
"There is room for improvement in detecting and preventing phishing attacks. While the solution performs well in some aspects, it struggles with phishing threats."
"Proofpoint Email Protection could improve by reducing the price."
"To improve Proofpoint Email Protection, I suggest breaking down the URL into one versus three different GUIs."
"Where it is not available, as is the case with unstructured data, this product fails miserably."
"What needs to be improved in Symantec Messaging Gateway is its local partner support, as it's not as technical. The support my company gets from the partner isn't good. Vendor support is good, but local partner support isn't. I'm happy with Symantec Messaging Gateway as a solution, but the problem is with its partner support. To me, Symantec Messaging Gateway is a complete solution, but it can be very difficult to search the web for resolutions to issues or problems you experience from it. If this could be improved or resolved in the next release of Symantec Messaging Gateway, then that would be good."
"Symantec Messaging Gateway should include better exclusions and exceptions for better administration."
"In a later release, it would be nice if the messaging gateway supported the cluster feature."
"The biggest problem is it's an on-prem product and we're trying to get out of having equipment in data centers."
"What needs to be improved in Symantec Messaging Gateway is its local partner support, as it's not as technical."
"Sometimes the solution picks up false positive for viruses during scans."
"They have updated the version of the Messaging Gateway and the new features they are adding the need to be re-evaluated. They have done some changes on the policy."
 

Pricing and Cost Advice

"Proofpoint is fairly expensive."
"Pricing has recently been increased and the cost is a downside"
"The licensing cost of Proofpoint Email Protection is a lot higher than other solutions, such as Barracuda."
"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 price of Proofpoint Email Protection a four out of five."
"Clients pay for an annual subscription of Proofpoint Email Protection. Every client always finds it expensive."
"In general, the pricing is competitive."
"The price is reasonable."
"Symantec Messaging Gateway’s pricing is very cheap."
"They're a little costly compared to Microsoft."
"A subscription for technical support costs extra."
"The cost of Symantec Messaging Gateway is too expensive in general. However, the appliance also includes the price of the license in the same bundle."
"It's a bit expensive compared to its competitor Barracuda Email Security Gateway but cheaper than Sophos Email."
"For 150 users, we pay INR 1,60,000."
