FortiMail is an email security platform developed by Fortinet, designed to protect organizations from a wide range of email-borne threats, including phishing attacks, malware, spam, and data loss. It offers comprehensive email security features to safeguard both inbound and outbound email traffic, helping organizations ensure the confidentiality, integrity, and availability of their email communications.

Here are some key aspects of FortiMail:

Anti-Spam and Anti-Malware Protection: FortiMail includes robust anti-spam and anti-malware engines that analyze incoming emails in real-time to detect and block spam messages, phishing attempts, malicious attachments, and embedded malware. These engines use advanced techniques such as heuristic analysis, reputation-based filtering, and signature-based detection to identify and mitigate email-based threats effectively.

Email Encryption: FortiMail supports email encryption to protect sensitive information transmitted via email. It offers encryption methods such as Transport Layer Security (TLS), Secure/Multipurpose Internet Mail Extensions (S/MIME), and Pretty Good Privacy (PGP), allowing organizations to encrypt email communications both within their internal network and with external recipients.

Data Loss Prevention (DLP): FortiMail includes DLP capabilities to prevent the unauthorized disclosure of sensitive data via email. It can inspect email content and attachments for predefined data patterns, keywords, or regular expressions that indicate sensitive information, such as personally identifiable information (PII), financial data, or intellectual property. Administrators can define policies to automatically block, quarantine, or encrypt emails containing sensitive data to prevent data breaches and compliance violations.

Email Authentication and Anti-Phishing: FortiMail helps organizations combat email spoofing and phishing attacks by implementing email authentication mechanisms such as Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC). These mechanisms verify the authenticity of email senders and detect unauthorized attempts to impersonate legitimate senders or domains, reducing the risk of phishing attacks and email fraud.

Policy-based Filtering and Quarantine: FortiMail allows administrators to define granular email security policies based on various criteria, including sender, recipient, content, attachments, and more. These policies enable organizations to enforce email security controls tailored to their specific requirements, such as blocking specific file types, restricting email delivery based on sender reputation, or routing suspicious emails to quarantine for further analysis.

Centralized Management and Reporting: Multiple FortiMail appliances can be centrally managed through FortiManager, Fortinet's centralized management platform, providing administrators with unified control and visibility over their email security infrastructure. FortiMail also offers comprehensive reporting capabilities to monitor email security events, analyze trends, and generate compliance reports for regulatory requirements.

Overall, FortiMail is a comprehensive email security solution that helps organizations protect their email communications against evolving cyber threats, ensuring the confidentiality, integrity, and availability of sensitive information exchanged via email.
