We started with our Trustmark including Buyer Protection for more orientation and real security when shopping online. Today, our feedback system brings real transparency to all digital sectors, far beyond just e-commerce, and we offer online shops legal services, ranging from protections against Abmahnungen (German legal warnings) to data privacy solutions.
