A growing challenger in the ad fraud prevention space, focused on protecting paid media budgets for performance marketers and agencies across multiple ad platforms
Lunio (formerly PPC Shield) is a UK-based AdTech company specializing in invalid traffic detection and prevention. The platform uses machine learning and behavioral analysis to identify and block fraudulent clicks, bot traffic, and other forms of invalid traffic across paid search, paid social, programmatic, and other digital advertising channels. By automatically excluding invalid traffic sources, Lunio helps advertisers protect their media budgets and improve campaign performance metrics. Founded in 2019 and rebranded from PPC Shield to Lunio in 2021, the company has positioned itself as a comprehensive ad fraud prevention solution for performance marketers and agencies. Lunio integrates directly with major advertising platforms including Google Ads, Meta, LinkedIn, and others, enabling real-time traffic analysis and automatic exclusion of fraudulent sources without requiring manual intervention. In the broader AdTech ecosystem, Lunio competes in the growing ad fraud prevention market alongside players like CHEQ, DoubleVerify, and Integral Ad Science. The company differentiates itself through its focus on paid media budget protection and its ability to work across multiple advertising platforms simultaneously, making it particularly appealing to performance-focused advertisers and agencies managing large paid media portfolios.
