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

"The stability and performance of the solution have been great, and we have not had any problems since we have been using it."
"I am satisfied with both the scalability and the stability of this solution."
"The most valuable feature of the solution is the tool's ability to prevent phishing attacks."
"These days, the threats by email are very high, and this solution provides our security."
"The most valuable feature of the solution is its interface, allowing users to get around the solution easily. The integration capabilities in the solution are also very easy."
"I love the integration between Fortinet products."
"A full-featured email gateway solution that contains security threats reliably."
"This solution is good for small and medium enterprise companies."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"With both of them working together, we have the perfect solution for mail."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"The most valuable feature is the straightforward setup."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
 

Cons

"Fortinet FortiMail could improve general user management. There are no password policies for users."
"They should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
"Limited ability to upgrade hardware may lead to some performance issues that might otherwise be improved."
"The product's cybersecurity features could be better."
"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."
"What's missing in Fortinet FortiMail is some sandbox information for some of the emails. It's probably configuration-based, where it could be configured on some emails. 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. At the moment, my company is okay with the current Fortinet FortiMail offerings, but in the past, because of a lack of understanding, my team wasn't able to quickly implement the geographical IP blocking feature. It was time-consuming to implement that feature, but that wasn't a fault of Fortinet FortiMail. The issue was from my team's end, but just by emailing the support team, that issue was resolved, so right now, there isn't any additional feature I'd like added to Fortinet FortiMail."
"Fortinet FortiMail should allow more flexibility with the content rules."
"The main area for improvement is the pricing."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The solution is not 100 percent stable and that can use improvement."
"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
 

Pricing and Cost Advice

"There is a license required for this solution."
"The pricing is on the higher side."
"The solution is reasonably priced compared to one of its competitors."
"FortiMail has extra charges for installation, configuration, and project management."
"Fortinet FortiMail has an annual license agreement."
"It is reasonable."
"There is either an annual or six-month charge to use this solution. Fortinet FortiMail is cheaper than Proofpoint or Cisco Security, or other email security appliances."
"Pricing is straight-forward and renewable without complicated pricing structures."
"The solution is not expensive."
"My company makes annual payments towards the licensing costs solution."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
