A security manager needs an automated solution that will take immediate action to protect an organization against inbound malicious traffic. Which of the following is the best solution?

Unified Endpoint Management (UEM) focuses on managing and securing endpoints within an organization, such as mobile devices and computers. While it plays a critical role in endpoint security, it does not directly monitor or respond to inbound network traffic, thereby lacking the capability to act against immediate threats from outside the network.

A Web Application Firewall (WAF) protects web applications by filtering and monitoring HTTP traffic between a web application and the Internet. While effective at blocking attacks aimed at web applications, it does not provide comprehensive protection against all types of malicious inbound traffic, limiting its capability compared to an IPS.

A Virtual Private Network (VPN) primarily secures remote access to a network by encrypting connections over the Internet. While it enhances privacy and security for remote users, it does not actively monitor or take action against malicious traffic targeting the organization, which is essential for immediate threat response.
