Dedicated servers eliminate the shared-hardware attack surface present in VPS environments. On a VPS, your hypervisor neighbors are other customers whose workloads could theoretically create side-channel risks (timing attacks, shared-memory exploits). On a dedicated server, you are the only customer on the physical machine. No hypervisor, no noisy neighbors, no cross-tenant visibility at any level.
For no-KYC operations handling sensitive data - journalism infrastructure, legal research, financial modeling - dedicated hardware provides a security foundation that VPS cannot match. The premium over VPS pricing reflects the physical hardware isolation you receive.
