Dell, one of the top three PC makers, will not be using Microsoft’s Pluton chip in “most” commercial PCs, The Register reported on Wednesday. A Dell representative told the publication that the security processor “does not align with Dell’s approach to hardware security and our most secure commercial PC requirements.”

Microsoft first announced the Pluton security processor in 2020. At that point, the chip had already been used in microcontrollers in the Xbox One and Azure Sphere to prevent hardware hacks.

In PCs, Pluton is meant to prevent hacks that could result from an attacker having physical access to the PC. Such physical hacks could result in malware installation or stolen data. By living on the main CPU’s die, Pluton can store protected data in an area that is isolated from the PC’s other components. According to Microsoft, that data can’t be removed no matter what.
