Senior Cybersecurity Engineer at a financial services firm with 11-50 employees
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

"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"This solution is easy to use."
"I highly recommend it as one of the best choices."
"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 has an efficient email filtering feature."
"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"The most valuable features are the endpoint defense features, it is very secure."
"After implementing FortiMail, the spam, and malicious emails we receive have significantly reduced, making it much simpler to manage."
"The anti-spam functionality is good and works well."
"Fortinet’s support services are good."
"At the end of the day, they look at the performance and the price, and Fortinet covers all the bases."
"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."
"The integration with FortiSandbox is good, and something that we utilize often."
"Technical support is great. They're available 24/7 and their response time is typically within the hour."
 

Cons

"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"The search area has room for improvement."
"We encounter issues while searching for missing emails."
"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."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"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."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"Online support sometimes takes up to a week to get back to you."
"The UI could be better."
"The main area for improvement is the pricing."
"The tool needs to improve its pricing policy. Also, it needs to be more user-friendly. I would want it to improve email security as well."
"Fortinet FortiMail can be improved in terms of its dashboard, which is small and not visually appealing, making deeper investigations difficult."
"The solution is user-friendly to a degree but the dashboard needs improvement."
"It's difficult for me to talk about areas for improvement in Fortinet FortiMail because I'm the general manager of the company and I'm an engineer with knowledge about the solution, but I'm not deeply involved in its implementation. As I mentioned previously, Fortinet FortiMail is also being used within the company, and I'm happy with its functionality, but sometimes, attacks pass and avoid the Fortinet FortiMail filters, but those could be very sophisticated attacks. There could still be an improvement in the filtering feature of the solution, though the security of Fortinet FortiMail is okay for me because I believe you can't implement one hundred percent security in any solution. The initial setup for the solution also needs improvement. The setup is supposed to be simple, but then the customer starts to complain that some of the false positive emails are reaching quarantine, so my team has to configure it again. There have been instances when Fortinet FortiMail rejects valid emails because some of the service partners of the customer have not been configured accurately, so the system considered valid mails as attacks to be quarantined, so aside from improving the filters, there should also be an improvement in the categorization of emails in the server. My team has to modify the configuration so that valid emails could pass and for Fortinet FortiMail to correctly filter the SPAM traffic. A feature that could be added to Fortinet FortiMail in its next release is advanced AI, so it can analyze and decide accurately on which mail is valid and which mail is SPAM."
"They should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
 

Pricing and Cost Advice

"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"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."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"Pricing is based on initial license purchase and use volume."
"Price-wise, the solution is not far from Microsoft ATP. So, it is affordable."
"We paid approximately $30,000 for the solution. It is less expensive than some other solutions. We have one license that carries all the features that we wanted."
"In the future I would like it if there's a possibility to lower the price of the bandwidth and UTM. It is quite expensive."
"FortiMail is not cheap."
"FortiMail has extra charges for installation, configuration, and project management."
"9,000 Euro per annum for Fortinet Mail and sandbox."
