Techniques are disclosed for public key infrastructure (PKI) based session authentication. An example network device includes one or more processors and memory coupled to the one or more processors. The memory stores instructions that, upon execution, cause one or more processors to: receive, from a source client device, a packet including a header for routing the packet to a destination client device specified within the header and metadata distinct from the header, the metadata specifying public key infrastructure (PKI) information and identity context information identifying a user or device participating in a session between the source client device and the destination client device; verify, based on the PKI information within the metadata, the metadata; and in response to verifying the metadata, apply, based on the identity context information, one or more policy rules for the session associated with the packet.
