Reviews from Real Users
Fortinet FortiMail stands out among its competitors for a number of reasons. Two major ones are its powerful anti-virus tool and its robust spam protection capabilities.
Flamur P., head of security management at Ipko Telecommunications, writes, "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."
Fortinet FortiMail was previously known as FortiMail.

| Senior Associate at a tech vendor with 10,001+ employees | 4.0 | I've used Fortinet FortiMail for a year to filter spam and phishing effectively, saving 20–30% of my time, though its dashboard and PDF filtering need improvement; overall, it's stable, scalable, and worth considering. |
| Head of the IT Security Division at a tech services company with 11-50 employees | 4.0 | I’ve used Fortinet FortiMail for over ten years; it’s reliable, easy to deploy, cost-effective, and ideal for on-premises mail protection, though it could improve speed and handling of signed PDFs to reduce false positives. |
| Head of computer systems at Indian Institute of Space Science & Technology(IIST) | 4.0 | I use Fortinet FortiMail as both a firewall and SMTP gateway to enhance email security with features like mail filtering and virus scanning. It's reliable, but it should improve to match cloud-based services and support virtual appliance migration. |
| Network & Security Engineer at Malam Engineering PLC | 4.0 | I use Fortinet FortiMail to protect our financial institution's mail servers from advanced email-based attacks such as ransomware and malware. Although its scalability and spam-blocking are impressive, improved documentation for deployment would be beneficial. The ROI process involves template-based client questionnaires. |
| System admin at Environment Fund | 5.0 | I use Fortinet FortiMail for email security, benefiting from its ease of use and effective threat detection. While the integration process could improve, it offers cost savings compared to Cisco, and I've observed a positive return on investment. |
| Cyber Security Specialist Level II & Certified SOC Analyst at BTGPR | 5.0 | I use Fortinet FortiMail to secure email platforms and generate security reports for clients. It's reliable, though complex rule setup can be challenging. Deployment and support are excellent, and I rate it a ten out of ten. |
| IT Manager at CNE | 4.5 | We use FortiMail to filter emails and block malicious ones automatically. It's easy to manage and integrates with other Fortinet products. While pricing is high, it provides consistent protection. We haven't switched vendors due to infrastructure costs. |
| Manager for Information Technology at BIC | 2.5 | We use Fortinet FortiMail primarily for anti-spam and phishing protection. The GUI is user-friendly and security policies are easy to configure. However, pricing could improve, and it should integrate more diverse threat-intelligence feeds beyond just FortiGuard. |
