Has faced challenges with configuration, taking actions, and learning curve but benefits from centralized management and good technical support
We have deployed Cisco Secure Email Threat Defense in two customer environments. It is still in development as a new product. Some customer requirements, such as sending logs to a Syslog server, are limited as ETD only supports sending audit logs. Customers have requirements for other system logs as well, which should be developed from their side. Another customer request is to restrict the IPs that can log in, which cannot be done from Cisco Secure Email Threat Defense yet. Any user with login details can log in. We can restrict the IPs in Cloud Mail Gateways, but not from Cisco Secure Email Threat Defense. It would be beneficial to improve this feature. Cisco Secure Email Threat Defense can take actions, such as requesting O365 to quarantine mail. In that case, the customer requires notification to the recipient from Cisco Secure Email Threat Defense. This option would be valuable if available. The real-time threat intelligence of Cisco Secure Email Threat Defense is an AI-based classification. It took one to two months to optimize the classification, but we still experience some false positives. Reducing the learning period would be beneficial. 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. Reducing the learning time would be much better. Additional features desired in the next release include IP restrictions and user logging IP restrictions, ensuring only the customer environment can log in to Cisco Secure Email Threat Defense. Logs forwarding needs improvement as currently it only has audit logs. In Cloud Mail Gateway, we can create an IPsec tunnel to forward logs. However, in Cisco Secure Email Threat Defense, there is no option, and we must do API integration to send logs. Only SIM can get logs; Syslog cannot retrieve them.

Effective threat protection with room for cost and usability improvements
There are some drawbacks that I would mention. To be frank, enterprises always look for cost benefits, so Kaspersky could implement some price benefits. Additionally, regarding know-how, if I am an experienced person it's fine, but when someone novice is working with it, they need information about why certain actions are required. Security is a field that is very vast, and implications are not known to everyone. In future updates, a quick walk-through and know-how features would be beneficial, such as information text at relevant places. This will increase usability. Feature-wise, an impact analysis would be a really good addition.

Quotes from Members

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

Pros

"The solution is stable."
"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
"On ease of use, it rates very high."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"Secure Email Threat Defense's scalability is good."
"I highly recommend it as one of the best choices."
"Cisco Cloud Mailbox is used for copying emails, anti-spamming, and securing the company's email, and we really enjoy the anti-spamming capabilities as well as the rejecting of bulk emails, which we can customize by adjusting the variables, and it is very user-friendly."
"Kaspersky Security for Internet Gateway has positively impacted our organization by helping us control unwanted attacks and limiting our exposure to risks."
"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"The most valuable features of the solution are the antivirus and child protection features."
"The most valuable aspect for me is the user-friendly interface."
"The most valuable features of this solution are its ease of use and operation efficiency."
"The most valuable feature of Kaspersky Security for Internet Gateway is the antivirus."
"The password thing is very good, and the overall URL protection."
"I would recommend it to others as it's easy to use."
 

Cons

"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."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"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."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"We encounter issues while searching for missing emails."
"The pricing could always be better."
"The search area has room for improvement."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"When I do a configuration, I do not know what implication it will have downstream."
"The customer support of the product is an area with shortcomings where improvements are required."
"There is room for improvement in terms of the pricing."
"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"I believe the absence of a procedure is the main issue."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
 

Pricing and Cost Advice

"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."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"The feedback from vendors and customer is that it is expensive."
"I rate the product's price an eight on a scale of one to ten, where one is very cheap, and ten is very expensive."
"Personal computer licenses can be expensive if you were to scale the solution extensively. However, large companies will most likely use Endpoint solutions and not this one."
"It is expensive."
"I would rate the pricing a seven out of ten, with ten being very expensive and one being cheap. It's neither too cheap nor too expensive."
"I am okay with the pricing."
"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
