BIG-IP Subscription IP Intelligence - subscription license (1 year) - 1 license

Using a frequently updated list of threat sources and high-risk IP addresses, IP Intelligence delivers contextual awareness and analysis of IP requests to identify threats from multiple sources across the Internet. The service draws on the expertise of a global threat-sensor network to detect malicious activity and IP addresses. Even when the BIG-IP device is behind a content delivery network (CDN) or other proxies, the IP Intelligence service provides protection by looking at the real client IP addresses as logged within the X-Forwarded-For (XFF) header. You can easily configure alarms or block traffic from a CDN with threatening IP addresses.
