Fortinet FortiMail Reviews Summary
Author infoRatingReview Summary
Senior Associate at a tech vendor with 10,001+ employees4.0I'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 employees4.0I’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)4.0I 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 PLC4.0I 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 Fund5.0I 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 BTGPR5.0I 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 CNE4.5We 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 BIC2.5We 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.
