What is most valuable?
FortiMail possesses notable strengths, and one key feature is its store-and-forward concept.
What needs improvement?
It could benefit from enhancing its functionality, especially in terms of advanced filtering. Introducing features such as AI-based and cloud-based filtering could significantly improve mail security. Fortinet should consider developing more robust protection mechanisms, particularly for cloud-based environments. Currently, users often refrain from placing Fortinet in front of Office 365 Exchange unless it's a cloud-based solution. 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.
What do I think about the stability of the solution?
I would rate its stability capabilities nine out of ten.

What do I think about the scalability of the solution?
Regarding scalability, the challenge lies in the licensing model tied to the hardware appliance. The current setup necessitates choosing between a higher or lower capacity appliance, creating inefficiencies. For instance, if you opt for a smaller appliance designed for up to a hundred users and the client has fewer users, you end up paying for unused capacity. On the other hand, choosing a higher-level appliance for a larger user base may result in unnecessary excess capacity and costs. It would be advantageous if Fortinet could address this issue by offering more flexible licensing options. This way, clients could pay for the specific number of users they have without being constrained by preset appliance capacities. This adjustment would enhance the scalability and cost-effectiveness of Fortinet's email security solution.
How are customer service and support?
Initially, when reaching out to Fortinet's tier-one support, we observed effective resolution of issues. However, at the entry-level, it seems that there's a repetition of updating tickets, and the problems persist. Having worked with Fortinet for an extended period, I've noticed a shift in the support dynamic. Either the personnel at the first level lack a complete understanding of the issues, or they are relatively junior, leading to extended resolution times for even minor concerns. Previously, their responsiveness was quick and efficient, with a maximum of 24 hours for a technical person to address an issue. However, recent changes in their approach may be contributing to the longer turnaround times. The process of logging a technical call and receiving a response has become somewhat extended, even for smaller issues. I would rate it six out of ten.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I often recommend exploring alternative products that diverge from the appliance-based approach. One notable option is Marshal from Paradigm, which was previously known as NetIQ. Marshal operates as software deployed on a server, handling inbound scanning, and forwarding emails based on established policies. This on-premises solution ensures that emails undergo scanning before reaching the main server, providing a robust layer of security. Other alternatives include GFI MailEssentials, Mimecast, and FortiGuard. Each of these products has its unique features and pricing structures. I've had positive experiences with Enhanced Security, our own rebranded solution. This cost-effective option is specifically tailored for SME segments, running seamlessly for the past four years. It is AI-based, cloud-based and has demonstrated its compatibility with various email platforms, including online exchange servers, on-premises servers, shared hosting, and Google Suite. Users have found it to be a reliable and efficient choice for email security.
How was the initial setup?
The initial setup of Fortinet is not suitable for everyone; it requires a solid understanding of how email systems function, making it less accessible for entry-level or junior technicians. Proper comprehension of mail concepts is crucial for a successful deployment. Incorrect configurations may lead to misleading outcomes, potentially causing disruptions in both incoming and outgoing emails.
What about the implementation team?
Upgrading the storage requires a more involved process, as it is not a simple plug-and-play scenario. Users must go through the entire setup again, which can be a cumbersome task.
What's my experience with pricing, setup cost, and licensing?
The pricing is on the higher side.
What other advice do I have?
While FortiMail provides a valuable option for those focused on transparent mail filtering or security solutions, it may not be the preferred choice for users accustomed to the features offered by platforms like Microsoft Exchange. In the SME segment, factors such as functionality, ease of use, and cost play a significant role. Many businesses in this category may find cloud-based solutions more appealing due to lower costs, simplified maintenance, and performance considerations. If an organization operates in the enterprise segment and has a substantial budget, considering Fortinet might be a viable option. However, for the SME segment, I would not recommend it due to the cost involved and the complexities associated with yearly renewals. Implementing Fortinet requires a level of technical expertise, particularly in understanding how mail servers function. Overall, I would rate seven out of ten.

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?
Fortinet FortiMail is a mail security gateway that you can deploy on cloud to secure your email on Office 365 or Gmail. You can use Fortinet FortiMail on an on-premises model also. Fortinet FortiMail is used to filter malicious or spam emails sent into a user's network.
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.

A stable tool to prevent phishing attacks
Pros and Cons
- "The most valuable feature of the solution is the tool's ability to prevent phishing attacks."
- "The sandboxing features are not well done in Fortinet FortiMail, making it an area of improvement."
What is our primary use case?
My company provides the tool to our clients or customers who want to control phishing and need a tool that offers DLP functionalities.
What is most valuable?
The most valuable feature of the solution is the tool's ability to prevent phishing attacks.
What needs improvement?
I haven't worked with Fortinet FortiMail competitors, but I feel whatever it does covers everything that is needed. I probably haven't had the chance to look at the products offered by Fortinet FortiMail's competitors. The tool fulfills the requirements of the client.
Fortinet FortiMail has certain shortcomings but can do well if it integrates with sandboxing features. The integration of tools with sandboxing features is something Fortinet can work on because it can change the way the product detects malicious activities. The sandboxing features are not well done in Fortinet FortiMail, making it an area of improvement.
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. There is no requirement for users to have real-time access when using the tool. The product does a good job in the way the messages are delivered, and in the way, the emails are scanned.
What do I think about the scalability of the solution?
It is a scalable solution.
My company caters to the needs of three or four customers of the solution.
My company's clients are mostly medium-sized enterprises.
How are customer service and support?
Fortinet FortiMail office provides good support to users. Within the region where I operate, the support offered by Fortinet is good, especially considering the taken by the technical team to resolve issues.
The longest time taken by the support team to resolve an issue is a day, and it is mostly because the support depends on the time you raise a ticket with the technical team, or it may be based on the support contract that a user has opted for in the company. Support also depends on the contract a user has chosen, which may include support for twenty-four hours and seven days a week in a year or eight to five support.
I rate the technical support a seven out of ten.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
In the past, I haven't worked with any commercial tools similar to Fortinet FortiMail, but I know a few online tools that can be integrated into our company's systems. I chose to work with Fortinet FortiMail since it was strongly recommended by someone who had been using it.
How was the initial setup?
With the right guidance, the product's initial setup phase is not that complicated. Fortinet FortiMail provides good documentation and a support team to help users.
The solution is deployed with the help of Open Virtual Appliance (OVA).
The time taken to deploy the solution depends on the organization, but generally, the deployment process takes around seven days to complete in SMEs.
What was our ROI?
The product has an immediate impact on its users after deployment because it lets them know how the attacks are being blocked, and it provides a good analysis of why a certain email or activity has been flagged. There is good feedback related to the product from users.
What's my experience with pricing, setup cost, and licensing?
It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it.
Which other solutions did I evaluate?
There are no tools similar to Fortinet FortiMail that are available because each product has its own way of functioning. Similar products will have many features that may be similar, so duplication of services is something a company wants to avoid. It is probably the better choice to select a product that is the easiest to use and offers a good support team.
What other advice do I have?
I rate the overall product an eight out of ten.

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?
