Systems and methods are provided for agentless attestation. Agentless attestation can measure the integrity of customer servers without requiring an agent software program to be downloaded to each of the enterprise computer devices. In particular, the system can integrate several standalone components to measure the integrity of monitored devices. This also allows the data center to authenticate, verify, audit, and update any hardware change, including a Platform Certificate.

Agentless attestation as a service

An example device may include processing circuitry and a management controller. The processing circuitry may include a communications interface that includes a first register and a second register. The first register may include a freshness bit and a number of first data bits. The second register may include a number of second data bits that correspond, respectively, to the first data bits. The processing circuitry may write variously to the first data bits in response to detected events, set the freshness bit in response to the management controller reading the first data bits, and reset the freshness bit if any of the first data bits are written to. The management controller may read the first data bits, perform predetermined processing based thereon, write to the second data bits based on the predetermined processing, and request a register transfer. The processing circuitry may, in response to the management controller requesting the register transfer, transfer values of the second data bits to their respectively corresponding first data bits if and only if the freshness bit is currently asserted.
