IPS vs. Firewall: What’s the Difference?

An IPS (Intrusion Prevention System) is a security measure that uses a variety of detection and prevention techniques to identify and block attacks before they occur. Firewalls are similar in function, but are designed to protect networked computers by blocking unauthorized access to network resources.

Both IPS and firewall technology are important additions to a security system. IPS can help protect against specific, known attacks, while a firewall can help protect against general unauthorized access.

In addition, both technologies can help identify and prevent malicious activity that may be taking place on the network.

Ultimately, the two technologies serve different purposes and should be used in tandem to best protect your systems.
