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.

Targeted email filtering has reduced spam and phishing and now saves significant investigation time
The best features of Fortinet FortiMail include its techniques and tactics, which are highly effective compared to other solutions such as Microsoft 365. Although Fortinet FortiMail may not be as advanced in some aspects, it is well recognized for its strong performance in handling spam and phishing. It performs thorough mail scanning and also offers a sandboxing feature that enhances protection. Fortinet FortiMail has had a positive impact on my organization by significantly reducing unwanted email activities such as spam and phishing. It provides accurate detection and generates results that often exceed what can be achieved through manual analysis. Since deploying Fortinet FortiMail, I have observed a reduction in investigation time by at least 20 to 30 percent.

Quotes from Members

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

Pros

"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."
"The product offers protection, email security, anti-spam, and antivirus."
"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 features and functionalities are much better than Microsoft's in-built Defender plan."
"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."
"I highly recommend it as one of the best choices."
"It has an efficient email filtering feature."
"This solution is good for small and medium enterprise companies."
"Fortinet FortiMail's most valuable features are its performance and security."
"The spam filtering is great."
"It is a scalable solution."
"FortiMail effectively filters all emails coming to our mail server, blocking malicious ones automatically."
"The deployment is simple and once up and running it is easy to manage."
"The solution is very, very stable."
"A full-featured email gateway solution that contains security threats reliably."
 

Cons

"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."
"The physical appliance has been discontinued, although the platform still exists."
"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."
"The pricing could always be better."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"The solution is a bit expensive."
"This solution could be improved by integration with Sandbox."
"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 biggest room for improvement would be the deployment. It will be hard for someone who doesn't understand the interface to deploy. If you understand it, you can find your way around the problems."
"There are features that other solutions have that this one is lacking, such as reporting options. I hope in future releases they advance their features list."
"Sometimes, the tool flags legitimate incoming traffic as spam."
"Maybe FortiMail's integration could be better."
"The solution's pricing is flexible and can be adjusted for African utility companies. Microsoft often offers special pricing formulas for African governments and organizations and it is similar to Fortinet FortiMail. In my country, government institutions receive discounted pricing from Fortinet FortiMail."
"Fortinet FortiMail's pricing could be improved."
"Sometimes it takes a little bit too long to determine if an email is good or not. If they could shorten that time span, it'd be so much better. It does delay our email, which does not make users happy. That said, I would have to say we have not been blacklisted for quite a while now."
"I think they need to look into it and improve their signatures. This will help with blocking incoming spam emails."
 

Pricing and Cost Advice

"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"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."
"This is a good solution and value for the money."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"I have no information on pricing for the competition because right now, my company is working only with Fortinet, but I can say that in general, the price for Fortinet FortiMail was accepted by the customers easily. The POC is also important when a customer is buying a solution. The customer wants to see how the product runs, and as Fortinet FortiMail is a stable product that runs without big issues, it has a bigger chance of getting chosen by customers over its competitors, even if its price may be a little higher. Pricing for the solution is competitive. Sometimes it's less, sometimes it's a little bit higher, but it isn't far from what other solutions charge."
"FortiMail has extra charges for installation, configuration, and project management."
"It is reasonable."
"Pricing is based on initial license purchase and use volume."
"I find Fortinet FortiMail pricing reasonable. There's no additional cost apart from its standard licensing fees."
"The pricing is good."
