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

"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."
"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"Cisco's technical support is very good."
"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."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"Secure Email Threat Defense's scalability is good."
"The antiphishing capabilities are very good."
"Its threat detection capabilities have been beneficial."
"It is a scalable solution."
"We're happy with things."
"Fortinet FortiMail's most valuable features are antispam, antivirus, database, and data loss prevention (DLP)."
"Fortinet FortiMail has a lot of valuable features. It works great. It also has an antivirus feature. Support for Fortinet FortiMail was also great when my team wanted to block some geographic IPs, but couldn't figure out how to do it. The support team provided clear communication on how to resolve that issue. Another valuable feature of Fortinet FortiMail is SPAM filtering which tells you how many spammy emails you've received. Based on my current use cases, I'm happy with Fortinet FortiMail."
"Both logging and reporting are very good, as well as the antivirus profiles, content emails, content profile, and application profile."
"The anti-spam functionality is good and works well."
 

Cons

"The physical appliance has been discontinued, although the platform still exists."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"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."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"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."
"I think they should improve Fortinet FortiMail on-premises by enhancing its user interface."
"The solution is user-friendly to a degree but the dashboard needs improvement."
"Fortinet FortiMail should allow more flexibility with the content rules."
"It is not easy to install."
"The IDE feature in Fortinet is not as good as the rest of the product because it's very difficult to deploy it."
"Fortinet FortiMail's pricing could be improved."
"For example, there was malware in some emails that weren't detected in some of the Fortinet FortiMail sessions, but it should have been configured from my company's end to better catch scam emails, but overall, the solution is okay."
"The area that could use some improvement in Fortinet FortiMail is the integration process. I would like the integration to be easier."
 

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."
"9,000 Euro per annum for Fortinet Mail and sandbox."
"You need to pay additional fees for premium support."
"Fortinet Fortimail has reasonable pricing."
"The solution is reasonably priced compared to one of its competitors."
"FortiMail is not cheap."
"Price-wise, you get what you pay for in Fortinet FortiMail. Apart from the licensing costs, no additional expenses are attached to the solution's pricing."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"There is a license required for this solution and it is on an annual basis. I am satisfied with the price."
