The signature-based Threat Prevention features of the firewall that are informed by intelligence from the Threat Intelligence Cloud include Vulnerability Protection, Anti-Spyware, and Anti-Virus. The Threat Intelligence Cloud collects data from a variety of sources, including global threat intelligence networks, and analyzes this data to identify new threats. This intelligence is then used to update the signatures for these features, allowing the firewall to detect and prevent known threats effectively.

Vulnerability Protection: Uses updated signatures to detect and block exploit attempts against known vulnerabilities.

Anti-Spyware: Detects and prevents spyware based on signatures and threat intelligence.

Anti-Virus: Blocks known malware based on updated virus signatures.

These features are continuously updated with new intelligence, ensuring the firewall can defend against the latest threats.
