DSA For Online Platforms and Marketplaces
In addition to the general obligations that apply to all intermediary services under the Digital Services Act (DSA), online platform operators must comply with specific additional due diligence obligations. These obligations are based on the requirements for hosting providers and are intended to ensure a higher level of transparency, accountability and user protection, among other things. This is intended to create a safer online environment and effectively mitigate systemic risks such as illegal content, manipulation and disinformation.
Online marketplaces that facilitate distance contracts between consumers and businesses play a special role. According to the DSA, they constitute a distinct ‘fourth level of regulation’. Operators of such marketplaces are subject to additional obligations, primarily to ensure the traceability of commercial providers and protect consumers from illegal or unsafe products.
These stricter obligations do not apply to micro and small enterprises. For the purposes of the DSA, service providers are considered to be small or medium-sized enterprises (SMEs) if they employ fewer than 50 people.
