Which tool does Fortinet use to enhance email security?

The correct answer is FortiMail, as it is specifically designed by Fortinet to provide advanced email security solutions. FortiMail offers multiple features that enhance the security of email communications, which include spam filtering, virus protection, and advanced threat detection. It functions as a secure email gateway that helps organizations protect against a wide range of email-borne threats, including phishing attempts and malware attacks.

FortiMail utilizes sophisticated filtering techniques and machine learning models to analyze incoming emails and block potential threats before they reach the end-users. It also includes features like encryption to secure sensitive communications, making it a comprehensive solution for organizations looking to protect their email infrastructure.

The other options, while related to cybersecurity, do not serve as dedicated tools for enhancing email security. For instance, FortiGuard provides threat intelligence services, but it is not a standalone solution for email security itself. Similarly, FortiCast does not exist as a recognized Fortinet product related to email, and FortiSpam is not widely recognized as a distinct Fortinet tool, but rather a general term that might describe spam filtering capabilities.
