GPU rental security review must separate tenant isolation, network protection

GPU rental security review must separate tenant isolation, network protection, and trust in the underlying host operator. A verified or reliable marketplace host is not automatically a trusted datacenter. SSH/TLS protects data in transit but does not prevent an administrator of an ordinary container host from accessing plaintext processed there. For sensitive workloads, verify the host tier and contractual controls before transfer; treat missing tier metadata as unconfirmed rather than proof of either classification. This applies to ordinary marketplace container rentals; it does not assess attested confidential-computing deployments.
