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.
Organizations running AIaaS platforms or analytics services on shared infrastructure need Lorica Private Pursuit to process sensitive customer data without exposing it to the platform itself, solving the trust problem that blocks enterprise adoption. The tool maps to all three NIST Protect functions,data security, platform security, and infrastructure resilience,because it encrypts data end-to-end while keeping computation isolated, meaning your customers' models and datasets stay opaque to you and your cloud provider. Skip this if you're building internal AI tools; the overhead only pays off when your business model depends on handling other people's confidential workloads.
