Intrusion Prevention Service (IPS) is a fully integrated security subscription for all WatchGuard appliances. It works in tandem with the application layer content inspection of the platform to provide real-time protection against network threats, including spyware, SQL injections, cross-site scripting, and buffer overflows. IPS scans traffic on all major protocols, using continually updated signatures to detect and block all types of threats. And because IPS is integrated with WatchGuard security appliances, you have an easy-to-manage, cost-effective solution without additional hardware to purchase and maintain.
