Blocking Clicks of Devices that are considered as old / outdated. The filter can be configured on absolute level and also with percentage thresholds to only block excessive amounts of old devices.
Threshold percentage: Percentage of total traffic at which Clickshield will start to reject Old Devices. When the threshold percentage is set to "0" no threshold will be computed and every Click from an Old Device gets rejected.
Minimum Request Count: To prevent false / too aggressive rejections there is a minimum threshold of requests that the user can set.
Lookback Time: The time clickshield looks back at the traffic to evaluate if the total amount of old devices exceeds the threshold.
Check on SubID Level: If enabled Clickshield will compute the threshold checks on SubID Level.
Filter by OS: This section defines what is considered an Old Device. This can be changed by the user by entering the minimum OS Version that is still considered to be up to date.
Filter by Browser: This section defines what is considered an Old Browser. This can be changed by the user by entering the minimum Browser Version that is still considered to be up to date.
