Which WatchGuard service provides real-time protection against viruses and malware?

The Threat Detection and Response (TDR) service is designed specifically to provide real-time protection against viruses and malware. It leverages advanced detection techniques and the ability to respond to threats as they occur, ensuring that any malicious activities are identified and dealt with swiftly. TDR continuously analyzes traffic and events to detect anomalies that may indicate the presence of malware or other threats, thereby enhancing the overall security posture of the network.

In contrast, the Intrusion Prevention Service (IPS) primarily focuses on detecting and preventing known threats and exploits by analyzing traffic for malicious patterns. While it contributes to network security, its primary function isn't specifically about real-time protection against malware in the same proactive manner as TDR.

The Firewall Manager serves a different purpose, mainly focused on the centralized management of firewall configurations rather than providing immediate protection against malware. It is an administrative tool rather than a security service.

The Content Filtering Service is geared toward controlling access to web content and can block known malicious sites or downloads, but it does not inherently provide real-time protection against malware in the same comprehensive and responsive way that TDR does.

Therefore, TDR is the most suitable option for real-time protection against viruses and malware.
