ClickGUARD can determine threat data in real-time when the click is happening by analysing the source of the click against multiple anti-fraud, blacklist, geo-location and various other services. Same goes for detecting proxies.
You can block a high threat IP address or an IP range to prevent it from seeing your ads and making more clicks. You can also exclude an ad placement that keeps bombarding you with clicks from IPs that are known threats.
By implementing known threat rules you'll be able to block sources that make clicks behind a proxy, or sources that present a medium or high level threat, as determined by the system.
How is threat level determined?
An IP address is classified as low, medium or high threat level based on thorough analysis of IP address history, so you can know if an IP address belonged to a fake crawler, port scanner, if it's hosting a bot or is a known attack source. IP addresses get blacklisted for various security reasons. Read more about how this works here.
How to configure?
Chose the threat type you wish to to observe (e.g. proxy) and the source you wish to apply the rule to (e.g. IP address), and switch on the rule. Then configure your threshold:
Make sure to hit "Save Changes" to apply the rule.
How long are IPs/ranges blocked for?
IP addresses will be blocked based on your default IP blocking period configured in Account Settings.
For how long are placements excluded?
Ad placements will be excluded based on your default ad placement exclusion period configured in Account Settings.
Additionally, you can override your default IP blocking / placement exclusion settings and chose how you wish to be notified when rules trigger. You can also apply custom click tags for advanced reporting.
