How does FortiGuard enhance network security?

FortiGuard enhances network security primarily by providing essential updates that protect against various threats. The service includes antivirus updates, which are crucial for defending against malware, viruses, and other malicious software that can compromise network integrity. Additionally, web filtering updates help in regulating the type of content that users can access, blocking harmful websites and preventing users from engaging with potentially dangerous online resources. This combination of antivirus and web filtering updates significantly strengthens the security posture of a network by ensuring that it is equipped to handle the latest threats effectively and maintain a secure environment for users and data.

The other choices do not accurately reflect how FortiGuard operates. Restricting user access to sensitive data is more related to access control policies rather than FortiGuard's focus on threat intelligence and updates. Automating network device configuration is a function that may involve other tools and services but is not a core feature of FortiGuard. Lastly, enhancing physical security of server rooms relates to infrastructure security rather than the digital protections offered by FortiGuard's services.
