An IPS is typically deployed inline to incoming traffic, scans for threats in most network protocols, and works at OSI Layer 4-7. WAF deployments protect web application traffic, while IPS deployments scan and protect at the network level by inspecting all packets. Why Do You Need A WAF And IPS Security Solution?Īn IPS compliments a WAF/WAAP solution and is typically deployed together. The IPS are usually deployed behind a firewall in a network and before a WAF.

What Is An IPSĪn intrusion prevention system (IPS) is a network security device that monitors a network at strategic points to scan for malicious activity and report, block or drop the malicious traffic as configured. Lastly, WAFs are transitioning from standalone tools into fully-integrated Web Application and API Protection (WAAP) offerings that include a suite of capabilities, including protecting APIs, bot management and mitigation capabilities, application Layer 7 DDoS protection, web application security, and more.

A WAF is focused on web application traffic (HTTP/S) and protects applications in internet-facing zones of the network.Ī WAF can use many techniques to understand whether traffic should be allowed to pass through to an application or should be blocked, including behavioral algorithms (machine learning and a positive security model) or a negative security model.

Why Do You Need A WAF And IPS Security Solution?Ī web application firewall (WAF) is a hardware appliance, virtual appliance or cloud-based service that resides in front or before the web-facing applications to detect and protect against a variety of malicious attacks.
