Leading performance marketers use Lunio to stop Ad Fraud in it's tracks!



Built by marketers, for marketers
Lunio tackles ad fraud as a marketing problem, not a security one.
Lunio has developed a sophisticated machine learning algorithm which analyzes ad click behaviors in real time to determine if a user is legitimate, suspicious, or invalid.
Lunio helps you understand the sources of your IVT and track changes in traffic quality over time. Easily spot spikes and take action to reduce wasted spend.
Lunio integrates with your ad platforms to automatically stop invalid users from seeing your ads. A fake user detected on one platform is automatically excluded from others.
Real people, real results
