CPU cache
The PrivateCore vCage product portfolio comprises vCage Manager and vCage Host. vCage Manager validates the integrity of x86 servers running Linux as well as the vCage Host. vCage Host installs on bare-metal servers and provides a hardened hypervisor based on KVM that can secure server random access memory (RAM) with AES encryption. vCage Host does this by loading a secure hypervisor into CPU cache and acting as a gateway to encrypt memory paging in and out between the CPU cache and RAM. vCage memory encryption leverages the KVM hypervisor but also has the potential to support other hypervisors. vCage Host supports existing KVM management tools.
