Systems and methods for detecting the presence or absence of a component on a circuit board are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include: a processor; and a memory coupled to the processor, where the memory includes program instructions store thereon that, upon execution by the processor, cause the IHS to: obtain current data from a current monitor, wherein the current monitor monitors current drawn by one or more monitored components of the IHS; and determine based, at least in part, on the current data, a presence or an absence of a required component of the one or more monitored components, or a presence of an unexpected component of the one or more monitored components.

Presented herein are systems and methods for the orchestrated secure attestation and conditional enablement of a hot-plug peripheral device. In one or more embodiments, a newly added peripheral device is initially set to a hidden status so that it is not visible to the host operation system of the information handling system. In one or more embodiments, only after being successfully vetted is the peripheral device made visible to the host. In one or more embodiments, if the peripheral device is not supported, including failing one or more policies, the peripheral device remains in a hidden state to the host operating system of the information handling system.
