Under the Cyber Resilience Act, does reliance on a cellular network or general internet connectivity require component-style due diligence toward the network provider?
Not necessarily.
The draft guidance's cellular-network example says such a network does not qualify as RDPS and should not be treated like a third-party component where no provider software is integrated into the product. The manufacturer still has to assess the network-related risks and address them through product-level controls.
