About company
Trusted Shops

For more than 25 years, Trusted Shops has been strengthening trust in online shopping. With our Trustmark, Buyer Protection and authentic reviews, we help millions of people make confident purchase decisions. More than 32,000 online shops across Europe rely on our trust solutions to build confidence, highlight reputable retailers, and grow sustainably.

Digital commerce continues to change rapidly. Fake shops, manipulated reviews and deceptively realistic online identities are on the rise – not least due to the growing capabilities of artificial intelligence in online retail. This makes it more important than ever to create reliable signals that make genuine quality clearly visible and give consumers peace of mind.

That is why we continuously develop and improve our solutions. Our goal remains clear: to make online shopping safer, more transparent and more trustworthy – for shoppers and online retailers alike. Today, Trusted Shops is one of the leading trust brands in European e‑commerce.
