Digital publishers are vulnerable to automated attacks, including insidious problems such as ad fraud, content scraping, skewed analytics, and form spam. Fraudsters deploy bots to scrape content, create false impressions, and generate illegitimate clicks on digital publishing websites and mobile apps. Invalid activity performed by bots also adversely affects user the experience, click-through rates, and tarnishes a publisher’s brand reputation. Radware Bot Manager applies a collection of supervised and unsupervised machine learning techniques to prevent invalid activity across digital media assets.
