1. A computer-implemented method comprising:
obtaining a request to retrieve transit path information corresponding to compute devices and network devices comprising a network enclave, the transit path information comprising proof of packet paths through nodes within the network enclave;
evaluating the compute devices, the network devices, and network connections among the compute devices and the network devices within the network enclave to obtain the transit path information;
determining, based on the transit path information verifying the packet paths, that the compute devices and the network devices comprising the network enclave are trustworthy;
generating, based on the determination that the compute devices and the network devices comprising the network enclave are trustworthy, a response to the request; and
providing the response to fulfill the request.
