CYSEC ARCA Trusted OS for Clouds
Enterprise and mid-market teams running sensitive workloads on public clouds need CYSEC ARCA Trusted OS for Clouds if isolation from cloud provider administrators is a hard requirement, not a nice-to-have. Hardware root of trust attestation at each VM boot combined with AMD SEV support on EPYC instances means your encryption keys stay genuinely inaccessible to CSP staff, which addresses PR.DS and PR.PS gaps that standard hardening cannot close. This is not for buyers seeking a general-purpose container security layer; ARCA is purpose-built for confidential computing scenarios where the threat model includes your cloud vendor itself.
Enterprise and mid-market teams protecting cryptographic operations or sensitive computation in physically accessible environments should evaluate Private Machines ENFORCER for its FIPS 140-2 Level 4 certification and hardware-enforced runtime integrity; the integrated HSM per compute blade and remote attestation cover both PR.DS and PR.PS in ways software-only key management cannot match. Skip this if you need edge deployment flexibility or support for non-x86 workloads, where the compact form factor advantage evaporates and operational complexity rises sharply.
