Device farms perpetrating mobile fraud are one of the most expensive and pervasive classes of mobile fraud. DeviceRankTM is the first, and only real-time solution to this challenge.

Device Farms

They are a marketer’s worst nightmare.

Criminals with warehouses full of real mobile devices, clicking on real ads, installing real apps and even generating real engagement. The devices and installs are as real as the budgets they are draining. To further hide their activities, criminals regularly reset their DeviceIDs (gaid or idfa).

Toute cette opération est quasiment indétectable.



DeviceRank builds on AppsFlyer’s mobile database — the largest anti-fraud database in the world. With over 5.7 billion mobile devices and over 1 trillion mobile events measured every month, DeviceRank has anonymously rated virtually all of the world’s smartphones, accurately identifying and blocking device farms in real-time.

Similar to the ‘bond ratings’ assigned by credit agencies, DeviceRank analyzes cross-publisher activity and rates device legitimacy based on a multi-point, anonymous profile. From legitimate, clean devices to fraudulent devices, DeviceRank’s unique combination of big data and machine learning continuously update device ratings, providing unparalleled protection.

Appareils frauduleux

The engagement profile of a fraudster is very different than that of a real user. For example, even the most active app users do not download dozens of apps, from geographically diverse locations, all from paid media, every day.

Appareils suspects

Certains profils d’engagement ont l'air très suspects, mais ne peuvent pas (encore) être formellement considérés comme frauduleux. Ces appareils reçoivent un classement « suspect ».

Nouveaux appareils

New Devices are DeviceIDs not yet rated by AppsFlyer due to a lack of engagement history. With nearly every device in the world (over 5.7 billion and counting) already rated, DeviceRank is the only anti-fraud platform that actively identifies and blocks device farms hiding behind DeviceID Reset Fraud.

Appareils LAT

Some mobile users prefer to maintain an extra degree of privacy by enabling “Limit Ad Tracking” on their devices. On average, about 15% of iOS users and fewer than 4% of Android users enable this feature and are subsequently rated as LAT devices. High concentrations of LAT devices usually originate from device farms.

Appareils sains

Real devices with healthy engagement profiles are rated as "Clean Devices". Ad networks, publishers or sub-publishers with high Clean Device rates serve as a useful benchmark in the Protect360 dashboard.
