IPS
In plain terms
A system that detects and actively blocks network threats.
Going deeper
An Intrusion Prevention System inspects traffic like an IDS but can automatically block or drop malicious activity in real time. It detects and acts.
Under the hood
Inline placement lets it prevent, not just alert; tuning matters to avoid blocking legitimate traffic.
Examples
Inline threat blocking, network security, automated prevention, next-gen firewalls.
Think of it like...
Like a guard who not only spots an intruder but also locks the door on them.
