An Intrusion Prevention System (IPS) is a network security technology designed to monitor network traffic for signs of malicious activity and automatically block or mitigate potential threats in real time. Unlike an Intrusion Detection System (IDS), which only detects and alerts on suspicious activity, an IPS takes a more proactive approach by intercepting and stopping malicious traffic before it can affect systems or networks.
