CYSEC ARCA Trusted OS for Clouds vs Plexicus Container Security: Side-by-Side Comparison (2026)

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.

Plexicus Container Security

Teams building containerized applications on tight budgets should evaluate Plexicus Container Security for its runtime threat detection and automated response capabilities, which catch post-deployment attacks that image scanning alone misses. The platform covers the full shift-left-to-runtime arc with hardcoded secrets detection, CVE scanning, Kubernetes policy enforcement, and continuous monitoring, mapping to NIST ID.RA and DE.CM functions most buyers actually need. Skip this if you're looking for a broader CNAPP that handles cloud infrastructure or VMs; Plexicus stays focused on containers and Kubernetes, which is exactly why smaller teams without dedicated platform security engineers will move faster with it.
