Which feature allows SonicWall devices to block incoming threats in real-time?

The Intrusion Prevention Service (IPS) is designed specifically to monitor network traffic in real-time, identifying and blocking potential threats as they occur. This proactive approach allows SonicWall devices to protect a network from various types of attacks, such as exploits, malware, and other security vulnerabilities. The IPS functions by analyzing traffic patterns, looking for known threat signatures, and applying security policies that can prevent those threats from infiltrating the network.

In contrast, the other features listed serve different purposes. Firewall Filtering primarily manages and controls access based on predefined rules but does not actively analyze or respond to threats like the IPS. Secure Remote Access enables safe connections to networks but is not focused on threat prevention. Web Filtering Service is aimed at controlling and managing web content access but does not provide the real-time diagnostic capabilities that the IPS offers in terms of threat detection and response. Therefore, the IPS is the appropriate feature for blocking incoming threats in real-time.
