Provides robust email security features but requires improved modernization and complexity management
Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

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

"Secure Email Threat Defense's scalability is good."
"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."
"It's very easy to deploy and configure."
"The solution is stable."
"It has an efficient email filtering feature."
"I highly recommend it as one of the best choices."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"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."
"Both logging and reporting are very good, as well as the antivirus profiles, content emails, content profile, and application profile."
"The biggest implementation my team has done for Fortinet FortiMail was for more than five thousand people, and the most valuable feature was its anti-spam feature."
"I would rate Fortinet FortiMail ten out of ten overall."
"They have a feature called CDR, Content Disarm, Reconstruction, click protection, and DLP for encryption purposes."
"After implementing FortiMail, the spam, and malicious emails we receive have significantly reduced, making it much simpler to manage."
"The spam filtering is great."
"Fortinet FortiMail is a very good product and reliable, and we find it easy to sell it."
"Through Fortinet FortiMail, we can perfectly authenticate each local mail service and mail release so that only authenticated mail goes out from our domain."
 

Cons

"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"The physical appliance has been discontinued, although the platform still exists."
"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 solution is a bit expensive. It could be cheaper."
"We encounter issues while searching for missing emails."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"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."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"The infrastructure could be improved. The data leak prevention could also be better."
"The area that could use some improvement in Fortinet FortiMail is the integration process. I would like the integration to be easier."
"The sandboxing features are not well done in Fortinet FortiMail, making it an area of improvement."
"I would like the integration to be easier."
"I would like it if the solution could be more affordable."
"An additional feature that could be added is a pop-up screen notifying you that an email has been blocked, without having to double click on it to take you there it could provide you with a summary explaining why it was on hold or why was it spam when you hover over it with your cursor."
"I need a stable update in the product that stays for a long time instead of having to deal with frequent updates."
"Improving the upgrade process, making it more user-friendly, and simplifying the management of hardware components could enhance the overall user experience and appeal of Fortinet's email security solution."
 

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."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"The solution is reasonably priced compared to one of its competitors."
"The tool is very expensive."
"The pricing is on the higher side."
"Fortinet Fortimail has reasonable pricing."
"If you don't need the full bundle that includes everything, you have options for the small or medium enterprise environments."
"It is an expensive product."
"The product's licensing part depends on the number of mailboxes and the hard disk needed by customers. The cost of the license depends on the number of mailboxes and the number of emails."
