What is the purpose of the FortiGuard service?

The FortiGuard service is designed to provide updated security feeds for various security services, which is essential for maintaining a secure network environment. It offers real-time threat intelligence and updates for antivirus definitions, intrusion prevention system (IPS) signatures, web filtering categories, and application control signatures. These updates are crucial for ensuring that Fortinet's security solutions, such as FortiGate firewalls, can protect against the latest vulnerabilities, malware, and emerging threats. By leveraging FortiGuard's continuously updated security feeds, organizations can enhance their defensive posture and respond effectively to evolving cyber threats.

The other options describe functionalities that, while important for network security and management, do not specifically align with the core purpose of the FortiGuard service. Managing firewall performance, monitoring network traffic, and configuring user access levels are tasks that involve different aspects of network administration and might utilize FortiGuard feeds, but they don’t capture the essential role that FortiGuard plays in threat intelligence and security updates.
