Which of the following best describes the functionality of FortiGate?

The functionality of FortiGate is fundamentally centered around its role as a firewall and VPN device. FortiGate firewalls provide essential security measures by monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. They employ features such as deep packet inspection, intrusion prevention, and application control to ensure that only legitimate and safe traffic is allowed through.

Additionally, FortiGate supports Virtual Private Network (VPN) capabilities, which enable secure remote access to the network for users. This makes it possible for organizations to extend their secure network reach to remote users while maintaining the integrity and confidentiality of the data transmitted.

While other options may describe functionalities related to various aspects of network security or IT services, they do not encapsulate the primary role of FortiGate as effectively as the description of it being a firewall and VPN device.
