Fortinet FortiMail and Mimecast Email Security are leading competitors in the email security category. FortiMail has a strong reputation for cost-effectiveness and versatile deployment options, whereas Mimecast is appreciated for its advanced gateway protection and seamless Microsoft 365 integration. On balance, Mimecast appears to have the upper hand due to its comprehensive suite of security features and user-friendly integration capabilities.
Features: FortiMail offers advanced bi-directional filtering, multi-layer threat detection, and cost-effective pricing without per-user costs. It integrates seamlessly with FortiGuard for real-time updates. Mimecast excels in gateway protection and sandboxing, ensuring email link safety and smooth integration with Microsoft 365. Additionally, it provides effective email archiving and targeted threat protection.
Room for Improvement: Fortinet FortiMail could enhance its documentation, third-party integration, and encryption features.

Mimecast benefits from straightforward deployment in cloud environments and generally good technical support, although its interface is considered complex and occasionally lacks responsive support.
Pricing and ROI: Fortinet FortiMail's hardware-based pricing is attractive for larger organizations, though some find it costly, particularly with extra fees for premium support.

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."
Mimecast Email Security is a comprehensive solution designed to safeguard organizations against advanced email threats. With an array of advanced security features, it provides robust protection against phishing attacks, malware, ransomware, and other targeted threats.
This product leverages Mimecast's extensive threat intelligence network to identify and block malicious emails before they reach the user's inbox. It employs sophisticated algorithms and machine learning techniques to analyze email content, attachments, and URLs, ensuring that only legitimate and safe emails are delivered.
One of the key features of Mimecast Advanced Email Security is its URL Protect capability. This feature scans all URLs within emails in real-time, checking for any signs of malicious activity. It blocks access to suspicious websites, preventing users from inadvertently clicking on harmful links and falling victim to phishing attacks or drive-by downloads.
Another notable feature is Attachment Protect, which scans all email attachments for malware and ransomware. It uses multiple layers of defense, including sandboxing and file conversion, to detect and neutralize any threats. This ensures that users are protected from opening malicious attachments that could compromise their systems.
Mimecast Advanced Email Security also includes Impersonation Protect, which guards against CEO fraud and other impersonation attacks. It analyzes email headers, domains, and sender behavior to identify suspicious emails that attempt to deceive users. By alerting users and administrators to potential impersonation attempts, it helps prevent financial loss and data breaches.
Furthermore, Mimecast Advanced Email Security provides comprehensive data loss prevention (DLP) capabilities. It scans outgoing emails for sensitive information, such as credit card numbers or social security numbers, and prevents accidental or intentional data leaks. This helps organizations comply with data protection regulations and maintain the privacy of their customers' information.
