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.
A setuid implementation of user namespaces that enables running unprivileged containers without root privileges as a secure alternative to traditional container runtimes.
