Njuskalo, Croatia's largest and most popular marketplace, has been a prime target for its competitors. Competitors scraped advertisements and user information from the portal. Advertisers also complained about transfer of ads without their consent. ShieldSquare helped Njuskalo strengthen its market position and create a safer platform for its buyers and sellers by securing their data. Now, content scraping and spam leads are completely stopped at Njuskalo. This talk was presented at Global Online Classifieds Summit 2018, Miami by Njuskalo.
