On R81.

 On R81.20 the IPS Blade is managed by the Threat Prevention policy. The Threat Prevention policy is a unified policy that includes Anti-virus, IPS, Anti-bot, and Threat Emulation software blades. The IPS blade provides protection against network attacks and exploits by inspecting the traffic and blocking malicious packets. The IPS blade can be configured with different profiles and exceptions to suit different security needs. References: R81 Threat Prevention Administration Guide, page 15.
