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.

Helps to detect and generate reports on phishing emails and saves from email compromises
We use the solution for marketing and brand protection.  I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature.  The product's…

Quotes from Members

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

Pros

"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"It has an efficient email filtering feature."
"It's very easy to deploy and configure."
"The solution is stable."
"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."
"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. 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."
"It is really important for large companies to have the brand protection that is provided by Agari."
"It comes with a lot of helpful tips for complicated areas."
"I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature."
"If spam or some kind of malicious email gets past Mimecast and gets into our email environment, we can go into Agari and we can search for it."
 

Cons

"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"The pricing could always be better."
"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."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"This solution could be improved by integration with Sandbox."
"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."
"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."
"We encounter issues while searching for missing emails."
"The protocol is quite complicated, which may not be something that could be improved, but it would be better if it was simplified."
"The product's user interface is clunky. We have difficulty in finding what we need. I would also like to see automation in the onboarding processes."
"Some customers in the financial sector do not like the cloud solution because they don't want data to be transferred to a US-based cloud."
 

Pricing and Cost Advice

"The solution’s pricing is manageable."
"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 feedback from vendors and customer is that it is expensive."
"The tool is not expensive and I would rate its pricing a four out of ten."
"The pricing depends on the number of users; per how many mailboxes you have, but they're pretty negotiable with that, too."
"The price of the licensing is based on the volume of email."
