Clawback feature performs well but analytics and integration capabilities need improvement
The integration capability with other threat intelligence platforms is not optimal, as I have experienced difficulty in sending logs to our SIEM. Cisco Secure Email Threat Defense's flexibility could be enhanced while it mostly integrates with cloud solutions, but not on-premise. The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious. Regarding room for improvement, the significant number of false positives should be addressed. The solution does not adapt to behavioral analytics and does not make changes when it sees a pattern.

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

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

Pros

"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"I highly recommend it as one of the best choices."
"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"This solution is easy to use."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"It has an efficient email filtering feature."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"The most valuable feature is the ability to remove bad messages that were delivered, prior to being classified as unwanted."
"Provides better control over emails, especially those sent via Office 365 on the cloud."
"Proofpoint provides an expandable project model, including DLP, email archiving, and encryption, which makes it a complete email security solution."
"The most valuable feature of Proofpoint Email Protection is the central location dashboard for viewing all the related information for risk."
"Proofpoint Email Protection is stable enough and does its job of virus, malware, and email scam detection. Setting it up is not too complicated."
"There is no downtime."
"As a cloud-based product, it can scale well."
"I recommend all of my customers to migrate and start using Proofpoint as it is secure, minimizes risk, and eliminates phishing attacks."
 

Cons

"The solution is a bit expensive."
"The physical appliance has been discontinued, although the platform still exists."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"We encounter issues while searching for missing emails."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"The initial setup is complex."
"The flexibility of the solution can be improved."
"The largest complaint that we hear from our customers is that there is no local support."
"It became very expensive due to the nature of local circumstances, and I may advise Proofpoint to adjust marketing solutions based on each country."
"Proofpoint Email Protection's interface is confusing and could be improved."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"They do not have an on-demand scan for the internal viruses and internal users, and they don't have a scan for the exchange server against viruses and spam as Symantec does."
"The product's deployment is complex and requires technical knowledge."
 

Pricing and Cost Advice

"It is expensive compared to other vendors."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The solution’s pricing is manageable."
"The feedback from vendors and customer is that it is expensive."
"Annually, it costs us about $92,000. This is pretty much what it costs us. There is no additional cost."
"It is expensive."
"It is multiple times more expensive, which made it very much less attractive."
"Proofpoint is fairly expensive."
"The price is reasonable."
"The tool's pricing depends on the customer's preference, offering options for an annual license or a monthly subscription. The cost varies based on factors such as the number of users and specific requirements. Overall, the pricing is competitive."
"Proofpoint Email Protection has comparable pricing."
"Clients pay for an annual subscription of Proofpoint Email Protection. Every client always finds it expensive."
