Intrusion Prevention System (IPS)

An Intrusion Prevention System (IPS) is similar to an IDS but goes a step further — it not only detects suspicious network activity but automatically takes action to block or prevent the threat. An IPS sits inline with your network traffic and can drop malicious packets, reset connections, or block attacking IP addresses in real time.

Most modern next-generation firewalls include IPS functionality built in. The key advantage over a standalone IDS is the automated response — threats are blocked without waiting for a human to review an alert and take manual action.
