Useful to filter out malicious or spam emails
Pros and Cons
- "The product's initial setup phase was very easy."
- "I need a stable update in the product that stays for a long time instead of having to deal with frequent updates."
What is our primary use case?
What is most valuable?
The most valuable feature of the solution stems from the fact that it has multiple profile sessions, like anti-spam sessions, content filters, and anti-virus. It has integration with sandbox also. You can ensure data leakage prevention through the content filter, and you can control file formats in both inbound and outgoing emails from the organization. An anti-spam technique and zero-day technique are characteristics of the tool, along with the ability to filter emails based on IP addresses or the domain of the sender.
What needs improvement?
As a customer, I need a stable update in the product that stays for a long time instead of having to deal with frequent updates.
For how long have I used the solution?
I have experience with Fortinet FortiMail.

What do I think about the stability of the solution?
It is a stable solution.
What do I think about the scalability of the solution?
In terms of scalability and availability, Fortinet FortiMail supports high availability for multiple appliances or devices. The to has the ability to configure cache rules.
My company has deployed the product multiple times on the cloud and on an on-premises model. Our company has also taken care of the deployment whenever the server or gateway were moved. In general, my company has dealt with a wide range of customers using the tool.
How are customer service and support?
The technical support for the solution is very good. The tool offers multiple levels of support, and most of the tickets can be resolved by the product's L1 support team. It is rare to use L2 or L3 support.
Which solution did I use previously and why did I switch?
In 2016, I worked with Cisco Secure Email, formerly known as Cloud Email Security. I think FortiMail is better in all areas compared to other tools. I still work with Cisco but focus more on FortiMail.
How was the initial setup?
The product's initial setup phase was very easy.
After the initial configuration of virtual machines or appliances, you create a connector to Exchange or the email server and create a security profile according to customer needs, then create a policy to control all incoming or outgoing emails of your customer's organization.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
With the DLP format, you can control the format or hash the emails that go outside your organization. In FortiMail, you can locate a shared directory, you can make a hash for every file on it and send them outside your organization, and can encrypt it if you want on identity-based encryption.
Fortinet FortiMail can be integrated with all email security products, like Exchange and Domino. The product is also integrated with AVI systems covered under Office 365 on cloud. The tool can be used if you want to inspect the emails internally in your organization to control malicious traffic.
I don't remember the tool's framework, but for FortiMail, updates and upgrades are meant to add new features and ensure more stability.
In terms of the value provided by the product, I feel that Fortinet FortiMail provides a good value to customers as it offers good security for emails, especially if you configure it the right way and integrate it with sandbox.
I rate the solution a nine out of ten.

The initial setup is easy. Anyone with an experience in email security solutions can install it. Deployment time depends on the environment; it may take as little as two days or up to two weeks. It requires one executive to implement and maintain it. The product needs tuning every one or two months for maintenance. The engineer has to check for email caches.
What's my experience with pricing, setup cost, and licensing?

Network Security Consultant at SigmaTelecom
Provides virus outbreak prevention and FortiSandbox integration
Pros and Cons
- "The most valuable features of Fortinet FortiMail are its virus outbreak prevention and FortiSandbox integration."
- "Fortinet FortiMail should allow more flexibility with the content rules."
What is our primary use case?
I have one deployment, which is a service provider, so it's working in a multi-tenancy environment. At least ten customers are being handled by this multi-tenant Fortinet FortiMail. We use Fortinet FortiMail mainly for incoming messages and also as a server.
How has it helped my organization?
In the first presentation we did, we were able to demonstrate to our client that 98.2% of the emails they received were spam emails. Furthermore, out of the spam emails, around 2,000 messages were found to contain viruses. Fortinet FortiMail was able to block these 2,000 virus-infected messages that would have otherwise gone unnoticed. Since we use Fortinet FortiMail as a multi-tenant environment in our cloud, we also save our customers' bandwidth as the spam emails are not downloaded.
What is most valuable?
The most valuable features of Fortinet FortiMail are its virus outbreak prevention and FortiSandbox integration.
What needs improvement?
Fortinet FortiMail should allow more flexibility with the content rules. FortiMail does not allow users to use the content itself as a matching policy attribute. This limits the flexibility of policy configuration, and we have to adapt by using specific sources to apply specific content filtering.
For how long have I used the solution?
I have been using Fortinet FortiMail for the past seven to eight years.
What do I think about the stability of the solution?
I rate Fortinet FortiMail a nine out of ten for stability.
What do I think about the scalability of the solution?
I rate Fortinet FortiMail an eight out of ten for scalability. We are expanding our customer base with Fortinet FortiMail because security is now perceived as an investment in Brazil.
How was the initial setup?
Fortinet FortiMail's deployment is straightforward. It's not like plug-and-play, but if you use the default configuration, you can enable very strict security without digging into the configurations.
What was our ROI?
Since we started offering the anti-spam with FortiMail as a service, we have moved from OpEx to CapEx.
What other advice do I have?
I am using the latest version of Fortinet FortiMail. Users need to understand the SMTP standards to configure Fortinet FortiMail properly. If you make mistakes in the configuration, you may allow users on the internet to use your email as an MTA. This was the mistake committed by one of our customers who tried to deploy the solution himself without proper knowledge. You must have some knowledge about the solution so you can internally configure it.
Overall, I rate Fortinet FortiMail an eight out of ten.
Which deployment model are you using for this solution?
Hybrid Cloud

Analista de Suporte at NCT Informática
Easy to implement with good integration and lots of features
Pros and Cons
- "I love the integration between Fortinet products."
- "In the Latin America market, some spam messages use Portuguese language. Some clearly spam messages would be better identified by the anti-spam if not for the language."
What is most valuable?
The Fabric aspect of the solution is excellent. With it, we have more accuracy in the classification. All the other functions and features on FortiMail are great. I love them all. It's really solid. All of the principal features on the market can be found in this product.
I love the integration between Fortinet products.
It's easy to set up.
What needs improvement?
The categorization of the emails, for example, from Brazil, could be better. In the Latin America market, some spam messages use Portuguese language. Some clearly spam messages would be better identified by the anti-spam if not for the language.
For how long have I used the solution?
I've been using the solution for about five years.
What do I think about the scalability of the solution?
We have three organizations on the solution. there might be as many as 1,000 people across them.
How was the initial setup?
The solution is pretty simple to set up. It's fast to deploy. In six hours we can deploy it. If you have experience in access with another component of the company, you will be fine. We did not find it to be complex.
What's my experience with pricing, setup cost, and licensing?
Typically, we pay for the solution on a yearly basis. I cannot break down exact costs as another area of my organization deals with licensing.
What other advice do I have?
I'd rate the solution eight out of ten. We are happy with its capabilities and its features.
Which deployment model are you using for this solution?
On-premises

Technical Manager at Triple C
A reasonably priced solution suitable for small to medium enterprises
Pros and Cons
- "The user quarantine feature in the solution is good...It is a stable solution."
- "The solution lacks to provide more visibility when there is a problem, and it needs to be tracked."
What is our primary use case?
Fortinet FortiMail is sufficient for our use cases.
What is most valuable?
The user quarantine feature in the solution is good. Not all the solutions have user quarantine features since they mostly have system quarantine features. The integration with Active Directory is great. The solution's antispam is really very efficient, especially the greylisting. Recently, the protection against impersonation is doing a great job.
What needs improvement?
The solution lacks to provide more visibility when there is a problem, and it needs to be tracked. The solution should provide users with more visibility so that they can track a problem.
For how long have I used the solution?
It has been only a very short time since I started using Fortinet FortiMail. I use it for my company and for our customers. My company has a partnership with Fortinet.
What do I think about the stability of the solution?
It is a stable solution.
What do I think about the scalability of the solution?
Regarding scalability, we did not receive any case where we had to expand. I recommend the solution to businesses that range from small to medium, including those who do not have a very large environment. It is possible to scale it more since we have one enterprise where it is deployed at a large scale.
How are customer service and support?
Fortinet's technical support is great. Usually, we do the first level of support. And when there is a really difficult problem, we raise tickets, and they are very good at handling such problems. I rate the technical support a nine out of ten.
How would you rate customer service and support?
Positive
How was the initial setup?
It is easy to deploy.
Regarding the time taken for deployment, If it is in gateway mode, then it will not take more than two to three hours. If such necessities are not there in place, it will take more time.
What about the implementation team?
We do the implementation. Also, we provide professional services since we sell the product with professional services.
What's my experience with pricing, setup cost, and licensing?
The pricing is reasonable, and this is why small to medium enterprises are adopting it. Price-wise, the solution is not far from Microsoft ATP. So, it is affordable.
Which other solutions did I evaluate?
What other advice do I have?
In fact, some vendors tried to work with us, but we found Fortinet to be very good.
Overall, I rate the solution a nine out of ten.

Easy to manage but issues with the current email search functionality
Pros and Cons
- "One major benefit of the Fortinet FortiMail product is its ease of management."
- "Issues with the current email search functionality."
What is our primary use case?
Email is a major part of communication in most organizations, and Fortinet FortiMail is used to protect the mail system from attacks and unwanted commercial emails. It is also used for authenticating the sender and ensuring secure communication.
What is most valuable?
One major benefit of the Fortinet FortiMail product is its ease of management. Second, it offers a sender authentication feature that can be used at the gateway or with third-party applications. These are some of the valuable features.
What needs improvement?
I would like to have an indicator for compromised features, also known as an IOC. My clients have issues with the current email search functionality. They have to search for emails and sometimes cannot find them because they don't have the current timestamp.
For how long have I used the solution?
I have been working with FortiMail for around seven years now, and it's one of the solutions that I use in my designs.
What do I think about the stability of the solution?
I would rate stability an eight out of ten.
What do I think about the scalability of the solution?
I would rate scalability a six out of ten. It has a flexible model, and it is effective for small, medium, or large companies.
How was the initial setup?
All Fortinet products are easy to implement. I haven't worked in a technical role for a while. But I have worked with FortiGate, FortiADC, and sometimes with FortiManager for the customer. It's not a complex solution.
Which other solutions did I evaluate?
I have used Cisco products. Fortinet model does not depend on users, whereas for Cisco, the licensing is dependent on the number of users. I do know that Cisco is more expensive for us than FortiMail.
What other advice do I have?
Overall, I would rate Fortinet FortiMail a seven out of ten.
Which deployment model are you using for this solution?
