What major benefit does FortiGuard services provide to FortiGate devices?

FortiGuard services offer a significant advantage to FortiGate devices by providing real-time threat intelligence and automatic updates. This is crucial for maintaining network security as it allows FortiGate devices to rapidly respond to new and evolving threats. The integration of threat intelligence means that the devices are continuously updated with the latest information on vulnerabilities, malware signatures, and attack methods. This proactive approach minimizes the risk of breaches and enhances the overall security posture by ensuring that the firewall is always equipped with the most current defenses.

In contrast, the other options focus on areas that are less directly related to the core functionality of FortiGuard services. Enhancing user interface design does not impact security effectiveness, while improving network speed and efficiency is more related to network management and optimization features rather than threat protection. Likewise, facilitating cloud-based storage for data, while beneficial in some contexts, does not relate to the primary purpose of FortiGuard services which is focused on threat intelligence and updates.
