An IDS (Intrusion Detection System) monitors network traffic for suspicious activity and alerts, but does not block it. An IPS (Intrusion Prevention System) also monitors, but can actively block or prevent detected threats in real-time. A Next-Generation Firewall (NGFW) combines traditional firewall functions with advanced features like application awareness, intrusion prevention, and deep packet inspection.
